First U.S. Case of Illness Arising From Occupational Exposure to Nanomaterials
Gen Re has published past articles about the potential for occupational exposure to nanomaterials to cause latent illness. Recently, a study reported the first case in North America of a worker handling nanoparticles in a U.S. laboratory setting where she developed a serious health issue:
“The study is the first reported or published case ever in North America of a worker handling nanoparticles in a U.S. manufacturing facility and developing serious health effects...A 26-year-old female chemist formulated polymers and coatings usually using silver ink particles. When she later began working with nickel nanoparticle powder weighed out and handled [in a laboratory setting she]...developed nickel sensitization when working with nanoparticle nickel powder in a setting without any special respiratory protection or control measures."1
This would seem to be a case of acute illness as the lab worker had only been working with nickel nanoparticles for one week. The worker periodically weighed out 1 to 2 grams of nickel nanoparticles without using protective measures. This is a very small amount (1 - 2 grams equals 0.035 - 0.070 ounces).
Keep in mind that laboratory workers were believed to have less exposure to powdered nanomaterials due to better controls than may be typically found in a manufacturing setting…As the Chicago song goes, “This may be only the beginning.”
On May 13, 2014 Nanotoxicology Inc. in the Magic City Morning Star described the report as “game changing.”
