Characterization of exposure to carbon nanotubes in an industrial setting
While production and use of carbon nanotubes (CNTs) is increasing, workers exposure to CNTs is expected to increase as well, with inhalation being potentially the main pathway for uptake. However, there have been few studies reporting results about workers' personal exposure to CNTs. In this study, worker exposure to single-walled CNTs (SWCNTs) during the production of conductive films in a modern up-scaling factory was assessed. Particulate matter concentrations (2.5–10 μm) and concentrations of CO and CO2 were monitored by using real-time instruments. Workers' exposure levels...
Les nanomatériaux manufacturés à l'horizon 2030
Conséquences en santé et sécurité au travail dans les petites entreprises en France Depuis le début des années 90, les nanomatériaux ont connu un développement fulgurant. Ils trouvent aujourd'hui des applications dans des secteurs aussi divers que le bâtiment, l'agroalimentaire, la cosmétique, la santé ou l'informatique... En matière de santé et de sécurité au travail, le principal défi est à présent d'anticiper les usages de demain pour imaginer et développer...
Safe use of nanomaterials
Commission publishes guidance for employers and workers This Guidance document offers an overview of the issues surrounding the safe use of MNMs in the workplace, sets out the broad outlines of preventive action and provides a practical tool for complying with specific aspects of ensuring workers' safety, such as risk assessment and risk management. This may be of particular value to those who may not have an in-depth technical understanding of the issues involved, and may assist in ensuring compliance with the Occupational Safety and Health (OSH) legislation when dealing with MNMs. Source...
Nanomatériaux - Ventilation et filtration de l'air des lieux de travail
Les situations d'exposition professionnelle aux nanomatériaux sont multiples et variées, que ce soit dans les entreprises ou les laboratoires de recherche. Compte tenu des inconnues qui demeurent quant aux effets potentiels des nanomatériaux sur la santé, il convient de prendre des mesures afin de réduire l'exposition des salariés au niveau le plus bas possible. La ventilation et la filtration de l'air des lieux de travail se révèlent être des moyens de prévention efficaces. Cette brochure fait un point sur le comportement...
Report of the questionnaire on regulatory regimes for manufactured nanomaterials 2010-2011
One of the objectives of the WPMN project on Co-operation on Voluntary Schemes and Regulatory Programmes is to gather information on the nanomaterials notified under the various regulatory regimes in OECD jurisdictions to provide an indication of regulatory activity and trends over time.

Le brochure est consitutée en 2 parties. La...
Avis et rapport de l’Anses relatifs à l’évaluation des risques liés aux nanomatériaux
Enjeux et mise à jour des connaissances Face à la diversité des nanomatériaux présents au quotidien et aux nombreux questionnements qui les entourent, l'Anses publie ce jour un état des lieux des connaissances sur les enjeux sanitaires et environnementaux des nanomatériaux manufacturés. Celui-ci permet de préciser les connaissances scientifiques et met en évidence des effets toxiques de certains nanomatériaux sur des organismes vivants et sur l'environnement. Il souligne aussi la complexité à appréhender...
Promotion of lung adenocarcinoma following inhalation exposure to multi-walled carbon nanotubes
Engineered carbon nanotubes are currently used in many consumer and industrial products such as paints, sunscreens, cosmetics, toiletries, electronic processes and industrial lubricants. Carbon nanotubes are among the more widely used nanoparticles and come in two major commercial forms, single-walled carbon nanotubes (SWCNT) and the more rigid, multiwalled carbon nanotubes (MWCNT). The low density and small size of these particles makes respiratory exposures likely. Many of the potential health hazards have not been investigated, including their potential for carcinogenicity. We, therefore, utilized...
Nanomanufacturing
Emergence and Implications for U.S. Competitiveness, the Environment, and Human Health Nanotechnology has been defined as the control or restructuring of matter at the atomic and molecular levels in the size range of about 1-100 nanometers (nm); 100 nm is about 1/1000th the width of a hair. The U.S. National Nanotechnology Initiative (NNI), begun in 2001 and focusing primarily on R&D, represents a cumulative investment of almost $20 billion, including the request for fiscal year 2014. As research continues and other nations increasingly invest in R&D, nanotechnology is moving from the laboratory...
Protecting the Nanotechnology Workforce
NIOSH Nanotechnology Research and Guidance - Strategic Plan, 2013–2016 Nanotechnology—the manipulation of matter on a near-atomic scale to produce new materials and devices—has the ability to transform many industries, from medicine to manufacturing, and the products they produce. By 2020, the National Science Foundation estimates, nanotechnology will have a $3 trillion impact on the global economy and employ 6 million workers in the manufacture of nanomaterial-based products, of which 2 million may be manufactured in the United States [NSF 2011]. Nanomaterials may present new...
Nanoparticules synthétiques
Gestion adaptative des risques à la santé et à la sécurité des travailleurs De plus en plus les nanotechnologies suscitent un grand intérêt autant sur le plan industriel que médical. Cependant, la production de nanoparticules synthétiques (NPS) continue de croître alors que les impacts sanitaires et environnementaux n'ont pas tous été évalués, amenant ainsi de nouveaux problèmes. Consécutivement à l'expansion du marché des nanotechnologies, le nombre de travailleurs...
Government backed nanotechnology products specification is published
Organizations designing, manufacturing, processing, importing and trading nanomaterials and nanotechnology-based products in the UK can now benefit from using PAS 137 Nanomaterials and nanotechnology based products – Guide to regulationand standards. The specification was developed by BSI, the business standards company and was sponsored by BIS (The Department for Business, Innovation & Skills). The use of nanomaterials and nanotechnology-based products for applications relating to certain sectors, such as food and pharmaceuticals, is subject to existing regulations that apply to these...
Current Strategies for Engineering Controls in Nanomaterial Production and Downstream Handling Processes
The focus of this document is to identify and describe strategies for the engineering control of worker exposure during the production or use of engineered nanomaterials. Engineered nanomaterials are materials that are intentionally produced and have at least one primary dimension less than 100 nanometers (nm). Nanomaterials may 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...
Nanotechnology and human health
Scientific evidence and risk governance Nanotechnology, the science and application of objects smaller that 100 nanometres, is evolving rapidly in many fields. Besides the countless beneficial applications, including in health and medicine, concerns exist on adverse health consequences of unintended human exposure to nanomaterials. In the 2010 Parma Declaration on Environment and Health, ministers of health and of environment of the 53 Member States of the WHO Regional Office for Europe listed the health implications of nanotechnology and nanoparticles among the key environment and health challenges...
