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...

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...

Guidance for manufactured nanomaterials from the Committee
The German Committee on Hazardous Substances (AGS) has issued Announcement 527 “Manufactured Nanomaterials”. The objective of the Announcement is to give recommendations for the protection of the safety and health of workers handling substances, mixtures, or articles consisting of, or containing, manufactured nanomaterials. The basis is the 2012 European Commission recommendation on the definition of the term ‘nanomaterial‘. Natural and incidental nanomaterials are not considered. Likewise, it does not address use by consumers. Though the announcement is indicative and complements...
