Biological monitoring of isocyanates and related amines. III. Test chamber exposure of humans to toluene diisocyanate.


Five men were exposed to toluene diisocyanate (TDI) atmospheres for 7.5 h. The TDI atmospheres were generated by a gas-phase permeation method, and the exposures were performed in an 8-m3 stainless-steel test chamber. The mean air concentration of TDI was ca. 40 micrograms/m3, which corresponds to the threshold limit value (TLV) of Sweden. The inhaled doses… (More)
