Abstract
In this thesis the concentration of diisocyanates namely hexamethylene
diisocyanate (HDI), methylene diphenyl diisocyanate (MDI) and toluene
diisocyanate (TDI) in indoor air samples and their respective metabolites
hexamethylene diamine (HDA), methylene dianiline (MDA) and toluene diamine
(TDA) found in workers’ urine were measured in fifteen polyurethane factories
located in the Tehran province, Karaj city and Mazandaran province in Iran.
Measurement of isocyanate concentration was performed using the NIOSH 5522
method. Measurement was conducted over three daily working shifts in fifteen
factories with a total of three hundred air samples.
