NIOSH Sees Data Gaps Making Analogues Key To Nanomaterial Reviews

A top official at the National Institute for Occupational Safety and Health (NIOSH) says the sheer number of engineered nanomaterials in use has made targeted toxicity testing impractical despite a reporting mandate forcing agencies to focus on identifying analogues they can use as the basis for risk assessments. “There are hundreds of thousands of engineered nanomaterials that exist or are going to be formulated in the near future. You can’t test all of them,” Chuck Geraci, NIOSH’s associate director for...
