Experimental study on respiratory sensitivity to inhaled toluene diisocyanate.

J Huang et al.

Archives of toxicology, 67(6), 373-378 (1993-01-01)

Groups of guinea pigs were exposed via inhalation to toluene diisocyanate (TDI) ranging from 0.02 to 1.0 ppm for 3 h/day on 5 consecutive days. Three weeks later, guinea pigs were challenged with TDI-GSA conjugates. Evaluations were based on TDI

Formation, solvolysis, and transcarbamoylation reactions of bis(S-glutathionyl) adducts of 2,4- and 2,6-diisocyanatotoluene.

B W Day et al.

Chemical research in toxicology, 10(4), 424-431 (1997-04-01)

During our ongoing studies of the reactions of toluene diisocyanate (2,4- and 2,6-diisocyanatotoluene, TDI) in vivo, it became apparent that reactive form(s) of these diisocyanates reach(es) the circulatory system after passage through the respiratory system. Based on recent work by

Development, validation and characterization of an analytical method for the quantification of hydrolysable urinary metabolites and plasma protein adducts of 2,4- and 2,6-toluene diisocyanate, 1,5-naphthalene diisocyanate and 4,4'-methylenediphenyl diisocyanate.

Carl Johan Sennbro et al.

Biomarkers : biochemical indicators of exposure, response, and susceptibility to chemicals, 8(3-4), 204-217 (2003-08-29)

Occupational exposure to diisocyanates within the plastic industry causes irritation and disorders in the airway. The aim of this study was to develop, validate and characterize a method for the determination of 2,4-toluenediamine (2,4-TDA), 2,6-toluenediamine (2,6-TDA), 1,5-diaminonaphthalene (1,5-NDA) and 4,4'-methylenedianiline
