Antibodies to toluene diisocyanate in an environmentally exposed population.
Residents living near a polyurethane foam manufacturing facility expressed concern to health officials over chemical emissions from the plant. Environmental monitoring of ambient air near the plant indicated the presence of toluene diisocyanate (TDI), which was used in foam production. Health officials collected blood samples from 113 residents and analyzed the blood sera for antibodies to TDI and related diisocyanates. Ten of the 113 residents (9%) had elevated levels of IgG or IgE antibodies specific for one or more diisocyanates. Exposure histories were taken from antibody-positive individuals to identify possible occupational exposure to TDI or the use of diisocyanate-containing consumer products. Exposure to TDI in ambient air may be responsible for the positive antibody responses detected in some residents of the community.
