Abstract:
A cross-sectio nal study was carried in order to investigate the relat inonship between carbon disulfide(CS
2)and the complatints and signs of nerv ous system in rayon wor kers.326 subjects exposed to CS
2 in a viscose rayon factory as a exposure group,105 workers from the same factory,not exposed to CS
2 or to any other neurotoxic agent,served as referents.The average CS
2 exposures of the low-level study group is below 10mg/m
3,and 31mg/m
3 in high-level group.Non-conditional multiple logistic regression analysis was used to check for statistical differences in SAS sof-tware.During the analysis,age,sex,worktime,body mass index,smoking,drinking,schooling and marriage state was adjusted.The odds ratio has significantly increaased of some complaints in workers exposed to CS
2 at levels below the present threshold limit value (10mg/m
3),as compared to controls.The dose-response relationship between the exopsure to carbon disulfide and the come;paints of nervous system was demonstrated.The pathological findings in clinical-neurological could not be detected except the sensitivity of temperature in person exposed to CS
2.The influence of low-level CS
2 on nervous sytem in workers could not be ingnored.
