A new sampling system is presented that uses solid sorbent media contained in a tube for the determination of airborne isocyanates (2.4-2.6 toluene diisocyanate, hexamethylene diisocyanate, and 4.4' diaminodiphenylmethane diisocyanate). The method is compared with the National Institute for Occupational

In recent years, epidemiological evidence that exposure to toluene diisocyanate (TDI) is associated with adverse health effects has led to the development of useful analytical methods for the biological monitoring of TDI. In this paper, an HPLC method is presented

To assess the nature and the time-course of the cellular component of airway inflammation induced by isocyanates, we examined nine subjects with occupational asthma induced by toluene- or methylene diphenyl-diisocyanate (TDI, MDI) and four control subjects never exposed to isocyanates.

Guinea pig hemoglobin (Hb) adducts of 2,4- and 2,6-toluene diisocyanate (2,4- and 2,6-TDI) were individually prepared, each at a Hb tetramer to diisocyanate ratio of 1:1, and compared with adducts of Hb from animals exposed to 1 ppm 2,4-TDI vapor.

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
