Biomonitoring exposure to styrene and styrene-(7,8)-oxide by repeated measurements

Aims: To investigat the use of urinary analytes and protein adducts as biomarkers of occupational exposure to airborne styrene (Sty) and styrene-(7,8)-oxide (StyOX) adopting a repeated measurements sampling design. Methods: Using this protocol (1 to 4 samplings), we sampled reinforced plastics workers (n=8), varnish workers (n=13), and control workers (n=22). Results: Median levels of personal exposure in these groups were 18.2, 3.4 and <0.3 mg/m3 for Sty and 133, 12 and
