Cytogenetic and DNA damage on workers exposed to styrene.
Styrene is a commercially important chemical widely used in the manufacture of synthetic rubber, resins, polyesters and plastics. The highest levels of human exposure to styrene occur during the production of reinforced plastic products. The objective of this work was to evaluate both DNA and cytogenetic damage in styrene-exposed workers, analysing only non-smoker individuals. Environmental lev...
متن کاملDetermination of albumin and hemoglobin adducts in workers exposed to styrene and styrene oxide.
Hemoglobin and albumin adducts of the carcinogen styrene-7,8-oxide (SO) were measured in 48 workers exposed to both styrene and SO in a boat manufacturing plant. Personal exposures to both substances were measured repeatedly over the course of 1 year (styrene:0.9-235 mg/m3 with a mean of 64.3 mg/m3 for 48 subjects; S0: 13.4-525 mu g/m3 with a mean of 159 mu g/m3 for 20 subjects). Cysteine and c...
متن کاملAssessment of sperm DNA integrity in workers exposed to styrene.
BACKGROUND Occupational exposure to toxic agents may cause infertility, congenital anomalies or death in offspring, but few studies have evaluated DNA integrity in germ cells of male workers. We investigated sperm DNA integrity in individuals occupationally exposed to styrene. METHODS AND RESULTS Semen samples were obtained from 46 male workers exposed to styrene and 27 unexposed controls (ag...
متن کاملSubclinical impairment of colour vision among workers exposed to styrene.
The effects of exposure to styrene were studied among 60 men aged 20 to 56 (mean 29.5) employed in shipbuilding. Exposure was due to the handling of glass reinforced polyester materials. The study was cross sectional and the workers were compared with a control group matched for age, social and occupational state, and ethnic origin. During the study, the mean atmospheric exposure to styrene was...
متن کاملKinetics of styrene in workers from a plastics industry after controlled exposure: a comparison with subjects not previously exposed.
Eight male workers from a glass reinforced plastics industry were experimentally exposed for 2 hours to 2.84 mmol/m3 (296 mg/m3) styrene during light physical exercise (50 W). About 63% of the amount supplied (4.6 mmol styrene) was taken up in the body. The arterial blood concentration of styrene reached a relatively stable level of 15 mumol/l at the end of exposure which was about 70% of the b...
