摘要：Diisocyanates are used as a initial chemical material in different factories such as surface coatings, polyurethane foams, adhesives, resins, elastomers, binders and sealants. In the polyurethane workplace there are aerosols of diisocyanates which has important to effect on workers. They can also be exposed to partial reaction of isocyanate-containing intermediates formed during polyurethane production. The main objective of this study pointed on assessment of exposure risk factors with MDI in the workplace, determination of MDI concentration and biomonitoring of MDA in polyurethane industries. NISOH (National Institute for Occupational Safety and Health) 5522 sampling and analysis method was used by midget impinger contained dimethyl sulfoxide with tryptamine. HPLC (High Performance Liquid Chromatography) was employed for air sampling analysis and GC (Gas Chromatography) for urine analysis. Getting personality data was carried out by Health Surveillance Questionnaire and multiple linear regression models with ANOVA test was used for the statistical analysis. The result of study showed that there was a diisocyanate pollution (MDI > 96.6μg/m³) and it have seen in the workers' urine. A new approach to assess isocyanate pollution in the workplace is risk factor assessment simultaneously with indoor air pollution and biological monitoring.
