目的了解某化纤企业二硫化碳(CS2)的污染水平.方法选择该企业有代表性的车间和工种,对作业工人接触CS2的浓度进行检测,同时,收集该企业历年来CS2浓度检测资料进行综合分析.结果 79.6％的工种接触CS2的短时间接触浓度≤10 mg/m3,92％的工种接触CS2的短时间接触浓度≤20 mg/m3;约70％的工种接触CS2的时间加权平均浓度≤5 mg/m3,约90％的工种接触CS2的时间加权平均浓度≤10 mg/m3,仅有个别工种作业工人接触CS2的时间加权平均浓度＞15 mg/m3或短时间接触浓度＞30 mg/m3.结论该化纤企业大部分工种作业工人接触CS2的浓度相对稳定在较低水平,但仍有相当一部分工种作业工人接触CS2浓度超过国家职业接触限值,今后仍需加强对CS2污染的治理.

Objective To investigate the exposure levels of carbon disulfide (CS2) for a chemical fiber industry.Methods The concentration of CS2 was monitored in representative workshops and types of work,and the datas of that over the years were collected.Results The short-term exposure concentration of CS2 about 80% of the type of work was less than or equal to 10 mg/m3,which of more than 90% was less than or equal to 20 mg/m3.The time weighted average concentration of CS2 about 70% of the type of work was less than or equal to 5 mg/m3,which of more than 90% was less than or equal to 10 mg/m3.The short-term exposure concentration of CS2 which was more than 15 mg/m3 or the time weighted average concentration of CS2 which was more than 30mg/m3 was only for little type of work.Conclusion The concentration of CS2 for the most type of work was lower,but there were still a number of types of work exposuring the higher concentration,which exceed the national occupational exposure limits.
