    <dc:creator>dchas</dc:creator><description><![CDATA[An electronic nose has been developed that uses colourful carbon dot films to detect and quantify nanoplastics in the air. The work, led by chemist and nanotechnology researcher Raz Jelinek from Ben-Gurion University, Israel, was presented at the autumn meeting of the American Chemical Society (ACS).

The new research builds on earlier work that Jelinek was involved with creating a sensor capable of detecting bacteria by the gases that they release. Jelinek’s team wondered if this simple and inexpensive carbon-dot-based technology would be able to detect nanoplastics – plastic particles less than 1µm wide – in the air.

Carbon dots don’t generate a signal on their own. But when a chemical from the air adsorbs to the dot their electrical capacitance changes, and that change is detected by the electronic nose.

The researchers made the carbon dots by heating a carbon source at relatively low temperatures for several hours. The heating process turned the carbon-containing material into colourful, and often fluorescent, nanometre-size particles. They then used the dots to create a film that formed the basis of their sensor. Changing the starting material gives the resultant carbon dots different surface properties meaning their affinity for different chemicals varies.

    <dc:creator>dchas</dc:creator><description><![CDATA[Scientists should be aware of the impact social media could have on their work. A new study shows that to reduce the chance of disruption due to legislative, regulatory or funding changes linked to public opinion, it is important to include social media when considering risk.

Finbarr Murphy, from the University of Limerick in Ireland, and colleagues performed a sentiment analysis of tweets between 2006 and 2020 relating to three areas of nanoscience – silver, carbon and titanium – to examine the public perception of nanotechnology. They found that overall public perception is slightly positive. But whilst positive events have little to no impact on tweet volume or perception, adverse events caused an increase in the volume of tweets presenting a negative opinion.

If an event is perceived badly enough to generate a twitterstorm, this decrease in public confidence could have far reaching impacts, with legislation, research funding and insurance coverage all susceptible to public opinion. As many research grants are through public funds, a large negative shift in public opinion towards nanotechnology could result in a decrease in funding available for research in that area.

A general statement on the effect of nanomaterials on people and the environment however is not yet possible. As part of the Leibniz Research Alliance „Nanosafety“, this project focuses on how laypersons and experts deal with conflicting scientific information on this topic and how they make decisions based on this information. We look at this research question with special regard to the internet as a source of knowledge.

Especially on the internet there is much (partially conflicting) information on the topic of nanosafety with different sources and varying quality. Using controlled as well as actual information environments, we are researching the handling of such fragile information by laypersons to see which strategies they use to resolve or explain possible contradictions. In another step we want to research how these strategies differ from strategies used by domain experts. To look into these processes we use methods such as eye-tracking and log file analysis.]]></description>

    <dc:creator>dchas</dc:creator><description><![CDATA[Nanotechnology underpins many emerging industries and technological innovations, such as artificial intelligence, quantum information science, and advanced manufacturing. Nanotechnology is a collection of sciences that encompasses chemistry, biology, physics, engineering, and advanced computing technology to create or manipulate materials or processes at the nanoscale. The nanoscale is the range from 1 to 100 nanometers. A nanometer is one-billionth of a meter. For reference, a sheet of paper is about 100,000 nanometers thick. Nanoscale matter can behave differently from the same material in a larger bulk form. For example, a material’s melting point, color, strength, chemical reactivity, and more may change at the nanoscale.1   

The small size and the corresponding large ratio of surface area to mass lead to a predicted greater biological activity per given mass for nanomaterials, relative to their bulk counterparts.2 Therefore, the properties and behavior of nanoscale forms of a compound cannot simply be extrapolated from those of their larger bulk forms.3 The nanostructure-dependent physical and chemical properties of many engineered nanoparticles may place them in the category of potential hazards. The direct risk that nanoparticles present to human health and to the environment will depend on the physicochemical characteristics of the surface and core of nanoparticles, on the probability of exposure occurring during each stage of their life cycle, and on the extent to which particulate materials exhibit interactions with biological systems associated with their nanostructure.

    <dc:creator>dchas</dc:creator><description><![CDATA[It may sound like something out of a futuristic science fiction film, but scientists have managed to engineer spinach plants which are capable of sending emails.

Through nanotechnology, engineers at MIT in the US have transformed spinach into sensors capable of detecting explosive materials. These plants are then able to wirelessly relay this information back to the scientists.

When the spinach roots detect the presence of nitroaromatics in groundwater, a compound often found in explosives like landmines, the carbon nanotubes within the plant leaves emit a signal. This signal is then read by an infrared camera, sending an email alert to the scientists.

This experiment is part of a wider field of research which involves engineering electronic components and systems into plants. The technology is known as “plant nanobionics”, and is effectively the process of giving plants new abilities.]]></description>

    <dc:creator>dchas</dc:creator><description><![CDATA[Kristen Kulinowski will head the Chemical Safety Board as its “interim executive authority” following the resignation of chair Vanessa Allen Sutherland, according to a CSB statement. The board will now be down to three members, two short of the number set by law. “I am committed to ensuring that the CSB’s current investigations are completed in a timely and efficient manner and that the lessons learned are available to industry, workers, and members of the public,” Kulinowski said. The board currently has 10 investigations under way. A longtime American Chemical Society member, Kulinowski was a research staff member in the Science & Technology Policy Institute of the Institute for Defense Analyses before being appointed to CSB in 2015. Earlier, she spent 13 years at Rice University as executive director of the Center for Biological & Environmental Nanotechnology and director of the International Council on Nanotechnology. At CSB, she has focused her outreach efforts on laboratory safety and safe practices for welding and other “hot work” in the chemical industry. The U.S. president nominates and the Senate confirms CSB members and the chair. President Donald J. Trump has twice proposed eliminating CSB.

    <dc:creator>dchas</dc:creator><description><![CDATA[For Gary Moore, the safety of the world outside his lab matters just as much as the people inside. An assistant professor in Arizona State University's School of Molecular Sciences, Moore develops chemicals and nanoscale materials using solar energy and other novel, green methods. For these artificial processes, he draws inspiration from the biological mechanisms that convert and store energy in nature.

But why research sustainable production if the research itself will damage the environment? By installing water-efficient equipment in his laboratory, Moore aims to make his research practices as green as the materials he makes. Assistant Professor Gary Moore (right) accepts the Laboratory Safety Innovation Award from Professor Jingyue Liu, chair of the safety and outreach subcommittee of the University Laboratory Safety Committee. Moore’s work to both conserve water and increase safety earned him the inaugural award. Photo by Darren Bowens Download Full Image

On April 10, Moore was awarded the 2018 Laboratory Safety Innovation Award to honor his innovations in safe science at the Tempe campus’ University Club. This was the inaugural year for the award, sponsored by ASU’s Laboratory Safety Committee in partnership with the office of Knowledge Enterprise Development and Environmental Health and Safety. The award was designed to highlight ASU’s dedication to safe science, recognizing a principal investigator for implementing an innovative safety program in an ASU research lab.

Moore’s lab was chosen for rising above and beyond green certification standards, incorporating technologies that both conserve resources and reduce flood and fire hazards.

“The consequences of destructive environmental practices reach beyond the local community, threatening the health and well-being of all those outside ASU,” Moore said.

    <dc:creator>dchas</dc:creator><description><![CDATA[Rapid growth in nanoscience and nanotechnology in recent years has been accompanied by studies of the toxicity and potential impacts of nanomaterials on human health and the environment, but less has been done concerning education in this area. There is therefore a need for courses that address this theme at universities worldwide, in order to improve the training of students, stimulate research in this area, and make information available to the wider population. The present work proposes a model for a theoretical and practical course for graduate students, introducing basic concepts of nanotechnology, methods for the characterization of nanomaterials, environmental applications, and potential toxic effects of nanomaterials in the environment. The course includes five theoretical and practical topics: (i) nanomaterials characterization, (ii) practical approaches, (iii) environmental applications, (iv) nanomaterials toxicity, and (v) integrated studies. These are designed to provide the students with a clear understanding of nanoscience and nanotechnology, addressing the main aspects of toxicity of nanomaterials, their correlations with physicochemical properties, and potential solutions for environmental problems. The teaching model was delivered to Master’s and Ph.D. students in a graduate program in Brazil, with highly satisfactory results.]]></description>

As a collaborator in that study, I was at the time heavily involved in exploring the risks and benefits of novel nanoscale materials. Back then, there was intense interest in understanding how materials like this could be dangerous, and how they might be made safer.

Fast forward to a few weeks ago, when carbon nanotubes were in the news again, but for a very different reason. This time, there was outrage not over potential risks, but because the artist Anish Kapoor had been given exclusive rights to a carbon nanotube-based pigment – claimed to be one of the blackest pigments ever made.

The worries that even nanotech proponents had in the early 2000s about possible health and environmental risks – and their impact on investor and consumer confidence – seem to have evaporated.

The microbiome also poses tremendous challenges for mapping and manipulating the entangled networks of interactions among myriad diverse organisms. Here, we describe the opportunities, technical needs, and potential approaches to address these challenges, based on recent and upcoming advances in measurement and control at the nanoscale and beyond. These technical needs will provide the basis for advancing the largely descriptive studies of the microbiome to the theoretical and mechanistic understandings that will underpin the discipline of microbiome engineering. We anticipate that the new tools and methods developed will also be more broadly useful in environmental monitoring, medicine, forensics, and other areas.

First, the agency will require registration under the federal pesticides law of products containing nanoscale silver that are designed to control microbes. EPA will not, however, classify all nanosilver products as pesticides, the agency says in a response to a 2008 petition from activist groups that are seeking stronger regulation of nanomaterials. The agency indicated it would not immediately act against unregistered antimicrobial nanosilver products, such as socks, now sold in the U.S.
Second, EPA separately proposed a one-time requirement for makers of nanoscale commercial chemicals currently on the market to notify the agency about all available health and safety data for their products. Under this Toxic Substances Control Act proposal, these manufacturers would also have to submit production volume and processing, use, exposure, and release information to EPA.]]></description>

    <dc:creator>dchas</dc:creator><description><![CDATA[President Barack Obama has nominated chemist Kristen Kulinowski to the Chemical Safety & Hazard Investigation Board (CSB), the White House announced Thursday.
Kulinowski, a science policy and nanotechnology safety expert, is a researcher at the Science & Technology Policy Institute, a think tank that provides analysis for federal agencies. Until 2011, she was a professor at Rice University, where she ran the International Council on Nanotechnology and a National Science Foundation Center for Biological & Environmental Nanotechnology.
“I’m honored to have been selected by the President for this important position,” she tells C&EN.
Kulinowski was a congressional science policy fellow from 2001–02 in the office of Edward J. Markey (D-Mass.), who was then in the House of Representatives but is now a senator. She holds a Ph.D. in chemistry
from the University of Rochester and is a member of the American Chemical Society, C&EN’s publisher.
If confirmed by the Senate, Kulinowski would fill the last open seat on CSB, which for years has operated with less than its full complement of five members.
From last June to December, CSB was down to two members. But in a last-minute push before adjourning in December 2014, the Senate confirmed Richard J. Engler and Manuel H. Ehrlich Jr. to the board. Engler, who was nominated in 2012, is a worker safety and environmental advocate. Ehrlich, who was nominated in January 2014, is a chemical industry emergency response and safety expert.]]></description>

    <dc:creator>dchas</dc:creator><description><![CDATA[Nanoparticles designed to adhere to and light up cancer cells have reached a major milestone in their bench-to-bedside journey. A first clinical trial of these ultrasmall, multifunctional particles has deemed them safe for humans and cleared easily by the body.

The particles, called “C dots” (Cornell dots), were invented more than a decade ago by Uli Wiesner, the Spencer T. Olin Professor of Materials Science and Engineering. They have been undergoing a U.S. Food and Drug Administration (FDA) Investigational New Drug (IND) human clinical trial since 2010. The results of that study, which involved five patients with melanoma, were published Oct. 29 in Science Translational Medicine and featured on the journal’s cover.

For the trial, which has been conducted at Memorial Sloan Kettering Cancer Center (MSKCC) in New York City, the 7-nanometer particles were labeled with radioactive iodine and injected into patients with metastatic melanoma. The iodine allowed the particles to be tracked with positron emission tomography (PET). Administered under the FDA’s IND guidelines, the study showed that the particles are safe for human use and leave no trace after renal excretion – an important benchmark for any substance undergoing IND approval. The trial has been amended to include patients with brain tumors, and those patients are being recruited now.

    <link>http://blogs.cdc.gov/niosh-science-blog/2014/05/28/nickel-nano/</link>
    <dc:creator>dchas</dc:creator><description><![CDATA[In an article published online May 8, 2014 by the American Journal of Industrial Medicine, researchers W. Shane Journeay, Ph.D., M.D., and Rose H. Goldman, M.D., MPH, report the case of a worker who developed sensitization to nickel when working with nickel nanoparticle powder.
According to the details of the case presented by Journeay and Goldman: “A 26-year-old female chemist formulated polymers and coatings usually using silver ink particles.  When she later began working with nickel nanoparticle powder weighed out and handled on a lab bench with no protective measures, she developed throat irritation, nasal congestion, ‘post nasal drip,’ facial flushing, and new skin reactions to her earrings and belt buckle which were temporally related to working with the nanoparticles.”The abstract continues, “Subsequently she was found to have a positive reaction to nickel on the T.R.U.E. patch test, and a normal range FEV1 that increased by 16% post bronchodilator.”1 
Journeay and Goldman add valuable new scientific evidence to the ongoing base of knowledge about the need for a proactive approach to addressing potential occupational health and safety implications of nanomaterials in the burgeoning global nanotechnology industry.   Case studies by alert clinicians are important to NIOSH and its partners in assessing risks posed by occupational exposure to nanomaterials, and in making recommendations for appropriate risk-management practices.

    <dc:creator>dchas</dc:creator><description><![CDATA[A 26-year-old chemist creating polymers and coatings with ingredients that included nanoparticles of nickel developed nasal congestion and facial flushing as well as temporary allergies to her earrings and belt buckle, a new report has found. She had to leave her job and could not even return to the building because her symptoms would start again, according to a May 12 article in the American Journal of Industrial Medicine.

This is the first reported case of illness from exposure to nanoparticles -- and it may not be the last. According to a co-author of the paper, the widely popular technology could prove to be a new health hazard, with unknown risks and uncertainty about how to protect workers -- and possibly consumers.

"This is case one in our modern economy," said Dr. W. Shane Journeay, a nanotoxicology expert and co-author of the study, in an interview with CBS MoneyWatch.

Nanotechnology -- the creation and use of substances whose ultra-small size makes the word microscopic seem huge by comparison -- has transformed a wide variety of industries. Nanoparticles are tiny pieces of often common materials whose chemical natures and reactions change because of the small size. The altered properties can lead to new applications in such industries as solar energy, paint, and cosmetics.

    <dc:creator>dchas</dc:creator><description><![CDATA[Engineered nanomaterials are materials that are intentionally produced and have at least one primary dimension less than 100 nanometers (nm). Nanomaterials have properties different from those of larger particles of the same material, making them unique and desirable for specific product applications.  The consumer products market currently has more than 1,000 nanomaterial-containing products including makeup, sunscreen, food storage products, appliances, clothing, electronics, computers, sporting goods, and coatings [WWICS 2011].
It is difficult to estimate how many workers are involved in this field. By one estimate, there are 400,000 workers worldwide in the field of nanotechnology, with an estimated 150,000 of those in the United States [Roco et al. 2010]. The National Science Foundation has estimated that approximately 6 million workers will be employed in nanotechnology industries worldwide by 2020.

    <dc:creator>dchas</dc:creator><description><![CDATA[Despite the increase in funding for research and the rising numbers of peer-reviewed publications over the past decade that address the environmental, health, and safety aspects of engineered nanomaterials (ENMs), uncertainty about the implications of potential exposures of consumers, workers, and ecosystems to these materials persists. Consumers and workers want to know which of these materials they are exposed to and whether the materials can harm them. Industry is concerned about being able to predict with sufficient certainty whether products that it makes and markets will pose any environmental, health or safety issues and what measures should be taken regarding manufacturing practices and worldwide distribution to minimize any potential risk. However, there remains a disconnect between the research that is being carried out and its relevance to and use by decision-makers and regulators to make informed public health and environmental policy and regulatory decisions.

    <dc:date>2013-11-12T15:57:36+00:00</dc:date>
    <link>http://ohsonline.com/articles/2013/11/11/niosh-releases-new-nanomaterial-control-recommendations.aspx?admgarea=news</link>
    <dc:creator>dchas</dc:creator><description><![CDATA[NIOSH has published new recommendations for controlling workers' exposures to engineered nanomaterials when such materials are used industrially. The agency's new document, "Current Strategies for Engineering Controls in Nanomaterial Production and Downstream Handling Processes," DHHS (NIOSH) Publication No. 2014-102, is available at www.cdc.gov/niosh/docs/2014-102/ and was posted Nov. 8.

The recommendations follow the standard hierarchy of controls, and the document is well illustrated with photos and diagrams of ventilation equipment, fume hoods, PPE, and other protective equipment. More than a thousand consumer products already on the market contain nanomaterials, including makeup, sunscreen, food storage products, appliances, clothing, electronics, computers, sporting goods, and coatings, according to the agency’s news release.

"As we continue to work with diverse partners to study the health effects produced by exposure to nanomaterials, particularly as new materials and products continue to be introduced, it is prudent to protect workers now from potential adverse health outcomes," NIOSH Director Dr. John Howard said. "These recommendations represent the kind of science-based guidance that our partners have requested, as a vital component for supporting the safe growth of nanotechnology and U.S. leadership in the global market."

The section on engineering controls – local exhaust ventilation, isolation, and dust suppression methods -- are likely to be the most effective control strategy for nanomaterials, but it also advises using elimination and substitution first if they are feasible. Administrative controls and PPE "may be less expensive [than engineering controls] to establish but, over the long term, can be very costly to sustain" and are less effective, the document states.

    <dc:creator>dchas</dc:creator><description><![CDATA[Silver nanoparticles (AgNPs), an effective antibacterial agent, are a significant and fast-growing application of nanotechnology in consumer goods. The toxicity of AgNPs released to surface waters during the use or disposal of AgNP-containing products will depend on the chemical transformations the nanoparticles undergo in the environment. We present a simple one-dimensional diagenetic model for predicting AgNP distribution and silver speciation in freshwater sediments. The model is calibrated to data collected from AgNP-dosed large-scale freshwater wetland mesocosms. The model predicts that AgNP sulfidation will retard nanoparticle oxidation and ion release. The resultant Ag2S-coated AgNPs are expected to persist and accumulate in sediment downstream from sources of AgNPs. Silver speciation and persistence in the sediment depend on the seasonally variable availability of organic carbon and dissolved oxygen. The half-life of typical sulfidized (85% Ag2S) AgNPs may vary from less than 10 years to over a century depending on redox conditions. No significant difference in silver speciation and distribution is observed between ≥50% Ag2S and 100% Ag2S AgNPs. Formation and efflux of toxic silver ion is reduced in eutrophic systems and maximized in oligotrophic systems.

    <dc:creator>dchas</dc:creator><description><![CDATA[One of the most cited inventories of nanotechnology-based consumer products is getting an overhaul. The database is the Consumer Product Inventory hosted by the Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars. Containing information about more than 1,000 manufacturer-identified nanotech products, it has not been updated since 2011, when funding for the project lapsed. “It will have a completely new look and a lot more features,” says Todd Kuiken, senior program associate with the Wilson Center’s Science & Technology Innovation Program. Researchers at Virginia Tech’s Institute for Critical Technology & Applied Science (ICTAS) are providing funding and some of the data for the upgrade, Kuiken says. The team of researchers, led by Matthew Hull, a program manager of research for the nano-bio interface and nanoscale science and engineering at ICTAS, is generating scientific information related to the environmental impacts of nanotech-based products throughout their life cycle. Data from that research, including potential exposure pathways, will be incorporated into the product inventory. Other experts will also be able to submit data to the inventory via an online log-in feature.

    <dc:creator>dchas</dc:creator><description><![CDATA[Little has been done across the federal government to integrate research on understanding the potential environmental, health, and safety (EHS) risks of nanotechnology, concludes a report from the National Research Council. The report calls for oversight of nanotechnology EHS research by a single agency at the federal level, with “sustained funding for this research and for the infrastructure needed to support data sharing.” The market for nanotechnology-enabled products is expected to surpass $3 trillion by 2015. Nanotech-based products on the market today include cosmetics, medical treatments, and electronics, but the uses of nanomaterials are changing rapidly, the report notes. “EHS research efforts are not keeping pace with the evolving applications of nanotechnology,” says Jonathan M. Samet, chair of the committee that wrote the report. The report highlights advances in characterizing nanomaterials but cautions that the potential effects of nanomaterials on human health and the environment are not fully understood, particularly with regard to future risk.

    <dc:creator>dchas</dc:creator><description><![CDATA[In studying the potential health effects of nanoparticle exposure, scientists rely on cell death as a key indicator. But new research suggests that nanoparticles might require additional safety testing. Brian D. Thrall of Pacific Northwest National Laboratory and his colleagues treated immune cells with iron oxide nanoparticles and showed that although the cells appeared healthy in standard toxicology tests, they struggled to perform one of their key jobs: engulfing pathogenic bacteria (ACS Nano 2013, DOI: 10.1021/nn402145t). The researchers exposed macrophages from mouse bone marrow to superparamagnetic iron oxide nanoparticles. They then added a lipopolysaccharide to the culture, which the macrophages treat as bacteria, and measured the cells’ gene expression with a micro­array chip device. The nanoparticles altered the expression of 1,044 genes by at least 50%. The most troubling changes, Thrall says, took place in oxidative stress and inflammation pathways, which play significant roles in macrophages’ ability to detect and clear bacteria. Indeed, when the researchers mixed the macrophages with Streptococcus pneumoniae, macrophages exposed to nanoparticles struggled to take up the pathogen, ingesting just half as much as unexposed cells.

    <dc:creator>dchas</dc:creator><description><![CDATA[A new study by researchers at the Illinois Institute of Technology shows that commercially available desktop 3D printers can have substantial emissions of potentially harmful nanosized particles in indoor air. The study, which was recently published in the journal Atmospheric Environment, is the first to measure airborne particle emissions from commercially available desktop 3D printers. Desktop 3D printers are now widely accessible for rapid prototyping and small-scale manufacturing in home and office settings. Many desktop 3D printers rely on a process where a thermoplastic feedstock is heated, extruded through a small nozzle, and deposited onto a surface to build 3D objects. Similar processes have been shown to have significant aerosol emissions in other studies using a range of plastic feedstocks, but mostly in industrial environments.

In this work, assistant professor Brent Stephens and graduate students in his Built Environment Research Group in the Department of Civil, Architectural and Environmental Engineering at Illinois Institute of Technology in Chicago, IL measured ultrafine particle concentrations resulting from the operation of a single type of popular commercially available desktop 3D printers inside an office space. Ultrafine particles (or UFPs) are small, nanosized particles less than 100 nanometers in diameter. The printers were used to print small plastic figures during normal operation. The resulting concentration measurements were then used to estimate UFP emission rates from these printers.

    <dc:creator>dchas</dc:creator><description><![CDATA[France is the first nation to take the bold step of requiring the mandatory registration of engineered nanomaterials (ENMs).(1) While the United States requires registration of new chemicals, some ENMs may not be deemed “new”. The French registry differs in specifically requiring the declaration of the use of all ENMs. Although the registry is somewhat limited in scope in that it involves no substantive evaluation or regulation of ENM use, it merits close attention in terms of the global nanotechnology enterprise. Observation of the impact in France and the European Union (EU) will provide important insights into the next steps that governments around the globe may take to obtain information about the commercial applications and safety of ENMs. This information is important for the assessment of nanotechnology environmental health and safety (nano EHS), as well as informing the public about the positive and negative impacts of this emerging new technology.

    <dc:creator>dchas</dc:creator><description><![CDATA[The majority of pure silver nanoparticles in consumer products are likely released into sewer systems and usually end up in wastewater treatment plants (WWTPs). Research investigating the reduction in nanoscale silver particles (n-Ag-Ps) has focused on the biological treatment process, generally in controlled laboratory experiments. This study, analyzing the field-collected samples from nine municipal WWTPs in Germany, is the first to evaluate the reduction in n-Ag-Ps by mechanical and biological treatments in sequence in WWTPs. Additionally, the concentration of n-Ag-Ps in effluent was determined through two different methods that are presented here: novel ionic exchange resin (IER) and cloud point extraction (CPE) methods. The n-Ag-Ps concentrations in influent were all low (<1.5 μg/L) and decreased (average removal efficiency of 35%) significantly after mechanical treatment, indicating that the mechanical treatment contributes to the n-Ag-Ps removal. Afterward, more than 72% of the remaining n-Ag-Ps in the semi-treated wastewater (i.e., wastewater after mechanical treatment) were reduced by biological treatment. Together, these processes reduced 95% of the n-Ag-Ps that entered WWTPs, which resulted in low concentration of n-Ag-Ps in the effluents (<12 ng/L). For a WWTP with 520000 t/d treatment capacity, we estimated that the daily n-Ag-Ps load in effluent discharge equated to about 4.4 g/d. Obviously, WWTPs are not potential point sources for n-Ag-Ps in the aquatic environment.

    <dc:creator>dchas</dc:creator><description><![CDATA[Nanomaterials end up in a wide range of consumer products such as cosmetics, clothing, and medications. And just like any other chemical or material used in such products, engineered nanomaterials fall under the jurisdiction of U.S. federal environmental, health, and safety guidelines. However, existing rules may be inadequate to regulate the new technologies, concludes a new study (Environ. Sci. Technol. 2013, DOI: 10.1021/es303591x). By slipping through these gaps in regulations, some nanomaterials may not receive appropriate risk assessments, the researchers say.
“The same properties that make nanomaterials so promising, namely that they behave differently than their bulk chemical counterparts, also make them very difficult to assess and regulate,” says Christian E. H. Beaudrie of the University of British Columbia, in Canada. Scientists can’t fully predict a nanomaterial’s physical and chemical properties before it’s created, so they can’t always determine how it might interact with humans or the environment, he says. This uncertainty contributes to how some kinds of new materials might escape federal oversight and rigorous risk review.
In their study, Beaudrie and his coworkers looked at how nanomaterials would be handled by several U.S. government agencies, including the Environmental Protection Agency and Consumer Product Safety Commission (CPSC). They examined how these agencies would deal with a nanomaterial over its life cycle—from production, commercial use, to disposal.
For example, a new material meant to be a pesticide would receive scrutiny from the EPA, which assesses the risks of pesticides before they enter the market. Meanwhile, CPSC can review products like children’s toys already on the market if the agency receives information suggesting the products’ materials are unsafe.

    <dc:creator>dchas</dc:creator><description><![CDATA[(Nanowerk Spotlight) In a previous Nanowerk Spotlight from last year ("Questionable safety practices in nanotechnology labs around the world") we showed that the nanotechnology research community does not exactly appear to be at the forefront when it comes to following, not to mention setting, standards for safe practices for handling nanomaterials. One of the most surprising results was that nearly three quarters of respondents reported not having internal rules to follow regarding the handling nanomaterials – approximately half of them didn't have rules and over a quarter were not aware of any internal regulations.
Researchers at EPFL (Ecole Polytechnique Fédérale de Lausanne) in Switzerland have now taken the initiative and presented a practical, user-friendly procedure for a university-wide safety and health management of nanomaterials, developed as a multi-stakeholder effort (government, accident insurance, researchers and experts for occupational safety and health).

As nanotechnology marches from the boundaries of laboratories to the home of a consumer, safety concerns should not be overshadowed by the success of the technology. A recent review article by Joseph H. Lavoie, a chemical engineer at the U.S. Army’s Natick Soldier Research, Development, and Engineering Center, tackles the safety concerns of nanomaterials in manufacturing and consumer products (Proc. Saf. Prog., DOI: 10.1002/prs.10388).

    <dc:creator>dchas</dc:creator><description><![CDATA[Back in the mists of time, I was approached with a crazy proposition – would I help co-edit a book on nanotechnologies regulation!  In a moment of weakness I said yes, and a little more than two and a half years later, the book is finally about to hit the shelves.

I actually think the resulting International Handbook on Regulating Nanotechnologies rather a useful, coherent and engaging collection of chapters – my co-editors Di Bowman and Graeme Hodge did a wonderful job encouraging a bunch of top thinkers in the field to write under occasionally whimsical but always relevant titles.

To whet your appetite prior to the book’s release sometime in November, here’s a sneak peak at the contents:
