The National Institute for Occupational Safety and Health (NIOSH) announced that laboratory studies, reported in a paper posted online by the journal Nature Nanotechnology on April 4, 2010, discovered that carbon nanotubes were biodegraded by an enzyme found in white blood cells, neutrophils.  According to NIOSH, the researchers demonstrated that, unlike carbon nanotubes that were not biodegraded in this way, the biodegraded nanotubes did not cause inflammation in the lungs of mice.  NIOSH...

On January 19, 2010, the National Institute for Occupational Safety and Health (NIOSH) announced three new peer-reviewed articles co-authored by NIOSH researchers. According to NIOSH, the articles report findings and conclusions from studies that examined issues related to potential occupational exposure to engineered nanomaterials. Two articles in the Journal of Occupational and Environmental Hygiene report on the design and application of the nanomaterial emission assessment technique,...

Last month, Bayer Material Science (BMS) announced that it derived an occupational exposure limit (OEL) of 0.05 milligrams per cubic meter (mg/m3) for Baytubes, BMS multi-wall carbon nanotubes. According to BMS, “[t]he latest results of sub-chronic inhalation studies support the conclusion that Baytubes act like poorly soluble particles.” BMS derived the OEL based on previous single and recent repeated inhalation studies. BMS states: “All relevant information...

The National Institute for Occupational Safety and Health (NIOSH) announced that it will hold a conference entitled “Nanomaterials and Worker Health:  Medical Surveillance, Exposure Registries, and Epidemiologic Research,” on July 21-23, 2010, at the Keystone Resort and Conference Center in Keystone, Colorado. According to NIOSH, the goal of the conference is to identify gaps in information and address questions focusing on occupational health surveillance, exposure registries, and...

The U.S. Environmental Protection Agency (EPA) has announced the Interagency Nanotechnology Implications Grantees Workshop, which will feature presentations on recent research by EPA, the National Science Foundation (NSF), National Institutes of Health, National Institute of Environmental Health Sciences (NIH/NIEHS), National Institute for Occupational Safety and Health (NIOSH), and Department of Energy (DOE) grant researchers.  According to EPA, the November 9-10, 2009, meeting “will...

The August 2009 issue of Nature Nanotechnology includes an article entitled “Essential Features for Proactive Risk Management,” written by Vladimir Murashov, Ph.D., Special Assistant to the Director of the National Institute for Occupational Safety and Health (NIOSH), and John Howard, M.D., former NIOSH Director. The authors “propose a proactive approach to the management of occupational health risks in emerging technologies based on six features:  qualitative risk assessment; the...

According to its website, the National Institute for Occupational Safety and Health (NIOSH) has joined the International Journal of Occupational and Environmental Health in inviting submission of scientific papers for a special issue of the Journal. The special edition is provisionally entitled “Human and Environmental Exposure Assessment for Nanomaterials,” and will be edited by Vladimir Murashov, Ph.D., a special assistant to the NIOSH Director. Submissions are due January 15,...

In a notice in the August 4, 2009, Federal Register, the Toxic Substances Control Act (TSCA) Interagency Testing Committee (ITC) released its latest report to the Administrator. Under TSCA Section 4(e), the ITC is required ‘‘to make recommendations to the Administrator respecting the chemical substances and mixtures to which the Administrator should give priority consideration for the promulgation of rules for testing.” According to the report, “the ITC has no...

The National Institute for Occupational Safety and Health (NIOSH) has posted a link to an article entitled “National Nanotechnology Partnership to Protect Workers,” which proposes the creation of a National Nanotechnology Partnership led by NIOSH. The article, posted online on July 7, 2009, by the Journal of Nanoparticle Research, suggests the partnership be a collaboration of government agencies, manufacturers, users, and others. The authors are John Howard, M.D. former NIOSH Director,...

On July 15, 2009, the National Institute for Occupational Safety and Health (NIOSH) announced plans to hold a conference entitled “Nanomaterials and Worker Health:  Occupational Health Surveillance, Exposure Registries, and Epidemiological Research.” The conference is intended to identify gaps in information about potential occupational health effects of nanomaterials, as well as address questions related to occupational health and safety. According to NIOSH’s website, the...
