title: Allergologic evaluation for workers exposed to toluene diisocyanate.
abstract: A cross-sectional investigation for allergology was performed of 15 painters exposed to high concentrations of toluene diisocyanate (TDI) (0.07-0.17 ppm) during the process of handling polyurethane varnish in a furniture manufacturing factory. Asthmatic reactions such as dyspnea, wheezing related to workshifts and contact dermatitis were observed in four and three cases respectively by questionnaire survey. Lung function tests on the painters showed significant decline in FEV1, %FEV1 and MMF compared to the referents. An increment in mast cell degranulation percentage could be seen in the painters. And also, patch testing with TDI were positive in five cases. From the results, it was suggested that both allergic pulmonary effects and contact sensitization had occurred in TDI-exposed painters in this factory.
