Are There Nano- and Microplastics in the Workplace?

The growing problem of plastic pollution in the environment is receiving an increasing amount of attention (see article in Nature). Small particles of plastics are often referred to as microplastics (plastic particles smaller than 5 mm [1]) and nanoplastics (the nanoscale fraction of plastic particles). Nano- and microplastic particles (NMPPs) can be formed through environmental Read More >

Nanotechnology Research at NIOSH

Engineered nanomaterials (ENMs) are materials that are intentionally produced to have at least one primary dimension less than 100 nanometers. These materials have new or unique properties different from those of larger forms of the same material, making them desirable for specific product applications. These properties can contribute to increased elasticity, tensile strength, electrical conduction, and reactivity. Consumer products using nanomaterials include Read More >

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 >

The Art and Science of OELs for Nanomaterials

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 >

Never fear! NEAT 2.0 is here! – How to perform nanomaterial exposure assessment in the workplace

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 >

Nickel Nanoparticles: A Case of Sensitization Associated with Occupational Exposure

  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 2014

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. Read More >
