New Review Article Supports Findings Regarding Previous Occupational Exposure Limits for Toluene Diisocyanate

A new review article from Gradient, an environmental risk sciences consulting firm, evaluated the basis of the American Conference of Governmental Industrial Hygienists' (ACGIH) decision to lower the occupational exposure limits, known as threshold limit values (TLVs) for tolune diisocyanate  (TDI). The review concluded ACGIH’s decision to lower the TLVs for TDI is “unlikely to result in fewer cases of occupational asthma” and “not adequately supported.”

The review, titled, “Critique of the ACGIH 2016 derivation of toluene diisocyanate Threshold Limit Values,” is available online now as open access in the journal Regulatory Toxicology and Pharmacology.
