Relation between colour vision loss and occupational styrene exposure.
Apart from uncertainties on study design adequacy and possible selection bias inherent to cross sectional studies, other issues often emerge from such studies in the industrial setting when trying to link rather subtle subclinical effects with neurotoxicant exposure. This is also the case in the study by Gong and colleagues, dealing with increased colour confusion index (CCI) in occupational st...
متن کاملRelation between colour vision loss and occupational styrene exposure level.
AIMS To investigate the relation between colour vision loss and the exposure level of styrene. Exposure level included the current exposure concentration, past cumulative exposure, and the maximum exposure level in the past. METHODS Colour vision was examined by the Lanthony desaturated panel D-15 test for 76 subjects exposed to styrene in a fibreglass reinforced plastics boat plant (as an ex...
متن کاملAntipyrine clearance during occupational exposure to styrene.
Animal experiments have indicated that styrene, which is a widely used organic solvent, may induce the microsomal enzyme function of the liver. Thirteen workers with long-term exposure to styrene in a polyester plant were investigated. They worked at air concentrations about the maximal allowed time-weighted average concentration of styrene in most Western countries (50 ppm). The clearance of a...
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 کاملOccupational Exposure to Styrene Vapor and Determining Risks of Health Consequences in Petrochemical Industry Workers
Introduction: Styrene (C₆H₅CH=CH₂) is known as one of the volatile organic substances produced or used in petrochemical industries. Exposure to this chemical compound can thus lead to respiratory diseases. Therefore, this study aimed to evaluate occupational exposure to styrene vapor and to determine the risks of its health consequences in petrochemical industry workers through a quantitative m...
