我国规定车间空气中二硫化碳(CS_2)最高容许浓度为10毫克/米~3,现上海提出修订值为5毫克/米~3,苏联已降至1毫克/米~3。我们对吉林化纤厂历年的车间空气中二硫化碳测定资料和1981年工人体检资料,做以分析讨论,供修订时参考。观察对象和方法我们对化纤厂纺练、原液、二硫化碳、酸站等车间接触二硫化碳作业工人171人做了体格检查,其中女工42人,年龄在19至52岁。体检着重做神经系统检查,对部分工人做了心电图、胆固醇、β-脂蛋白等检查。该厂自1973年以来,每半个月测定一次车间空气中二硫化碳浓度,应用二乙胺醋酸铜比色法。结果一、车间空气中二硫化碳浓度现将1973-1981年各有关生产工序的空气中CS_2浓度测定结果列于表1。
China has stipulated that the maximum allowable concentration of carbon disulfide (CS_2) in workshop air should be 10 mg / m 3. Now Shanghai proposes a revised value of 5 mg / m 3 and the Soviet Union has reduced it to 1 mg / m 3. We have Jilin factory chemical fiber factory in the air over the years carbon disulfide determination of data and 1981 workers physical examination data, to analyze and discuss for reference when revising. Observation objects and methods We conducted a physical examination of 171 workers exposed to carbon disulfide in chemical fiber plant spinning and weaving, liquid, carbon disulfide, acid station and other workshops, of which 42 were female workers, aged 19 to 52 years old. Physical examination re-examination of the nervous system, some workers did ECG, cholesterol, β-lipoprotein and other tests. The plant since 1973, measured once every two months, workshop carbon disulfide concentration, the use of diethylamine copper acetate colorimetric method. Results 1. The concentration of carbon disulfide in the air of the workshop The results of determination of the concentration of CS_2 in air at various relevant production processes from 1973 to 1981 are shown in Table 1.
