||Air and biological monitoring of toluene diisocyanate in a flexible foam plant
||Mar. 1997, Vol.58, No.3, p.229-235. 20 ref.
||Comparative air measurements of toluene diisocyanate (TDI) were performed at a TDI flexible foam plant. Urine and plasma samples were also analyzed. Sampling of isocyanates on glass-fibre filters impregnated with 9-(N-methyl-amino-methyl)-anthracene and glycerol followed by liquid chromatography-ultraviolet determination proved to be a robust and reproducible method for the determination of concentrations well below the threshold limit value. Sampling during several hours was possible. Filter-tape measurements enabled the estimation of isocyanate exposure during a whole workday. Levels of 2,4- and 2,6-toluene diamine in urine reflected exposure during the past few hours, and plasma levels reflected exposure during the past several days.
