Sažetak The paper brings the preliminary results of ambient and biological monitoring of exposure to xylene, toluene, and styrene in paint industry. Air samples were collected at seven stationary locations at work places of 31 male workers. Samples of venous blood were taken from all workers for styrene, toluene, and xylene analysis, and of urine for metabolic derivatives, mandelic, phenylglyoxylic, and o- and m-methylhippuric acids analysis. Blood was collected on Wednesday before and after work, and urine on Monday, Wednesday and Thursday before work and on Wednesday after work. Workers were exposed to moderate concentrations of xylene and low concentrations of toluene and styrene. During periodic medical surveillance Questionnaire 16 was applied as a screening test for early central nervous disturbances. Seven workers had positive findings and required further psychological tests as recommended by WHO. Risk assessment of combined long-term exposure to organic solvents in occupational environment requires a prospective epidemiological study with matched control group.
