WHO Guidelines to Protect Workers from Nanomaterials
Introduction from NIOSH Director, John Howard, MD The National Institute for Occupational Safety and Health (NIOSH) has been at the forefront of research on working safely with nanomaterials. NIOSH leads the U.S. federal government health and safety initiative for nanotechnology coordinating research and activities through the NIOSH Nanotechnology Research Center (NTRC) established in 2004. The Read More >

This guest blog post from our Finnish colleagues summarizes the challenges of identifying OELs for new nanomaterials as part of the development of a WHO guideline for working safely with nanomaterials. Engineered nanomaterials are fascinating. Just by making stuff smaller researchers have discovered forms of materials and even completely new materials that can be Read More >

Happy New Year. As we start afresh in 2017 I wanted to share my recent editorial in the British journal, Occupational Medicine, “Occupational health issues in the USA”. The article highlights some of the occupational safety and health issues identified as needing attention by the industry sector groups of the National Occupational Research Agenda (NORA). Read More >

Do you think you might have exposure to nanomaterials in your workplace? Never fear! NEAT 2.0 is here! Engineered nanoparticles are unique. They are generally smaller than both red blood cells and viruses, don’t weigh much, and have a great amount of surface area proportionate to their size. These particles are increasingly used in a Read More >

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 Read More >

Workers Memorial Day, April 28, reminds us that every death, injury, or illness on the job represents a human tragedy. Behind each statistic is the loss of a loved one’s life, the diminution or loss of a father’s or mother’s ability to provide for family needs, or a medical crisis that can have lifelong consequences.

Background 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 Read More >

Earlier today, at the annual meeting of the Society of Toxicology, NIOSH researchers reported preliminary findings from a new laboratory study in which mice were exposed by inhalation to multi-walled carbon nanotubes (MWCNT). The study was designed to investigate whether these tiny particles have potential to initiate or promote cancer. By “initiate,” we mean the Read More >
