【摘要】：目的观察高水平接触煤焦油沥青(CTP)对职业人群的早期健康危害。方法采用判断抽样方法,以2家炭素厂294名CTP作业工人为调查对象。采用个体采样法检测调查对象CTP接触水平,并对其进行在岗期间职业健康检查。结果 2家炭素厂11个岗位的CTP作业工人接触CTP的周时间加权平均浓度中位数(第0~100百分位数)为33.7(13.2~41.6)mg/m3,超过国家职业卫生限值67~205倍。294名CTP作业工人中,呼吸系统不适症状、皮肤症状、眼部刺激症状和其他症状检出率分别为11.6%、8.2%、6.1%和3.7%。女性CTP作业工人呼吸系统不适和皮肤症状检出率均高于男性(17.2%vs 7.6%,20.7%vs 5.1%,P0.05),饮酒CTP作业工人眼部刺激症状检出率高于不饮酒者(13.2%vs 3.7%,P0.05)。结论高水平CTP接触对作业工人健康危害的早期症状包括呼吸系统、皮肤和眼睛的损害,性别和饮酒可能是其影响因素。
[Abstract]:Objective to observe the early health hazard of high level exposure to coal tar tar pitch (CTP) to the occupational population. Methods 294 workers exposed to CTP in 2 carbon plants were investigated by the method of judging sampling. The CTP exposure level of the investigated subjects was detected by individual sampling method. Results the weighted mean weekly average concentration of exposure to CTP of CTP workers in 11 positions in 2 carbon plants was 33.7 / 13.2 / 41.6 mg / m ~ (3), which exceeded the national occupational health limit. Of the 67-205-fold. 294 CTP workers, Respiratory symptoms, skin symptoms, The detection rates of ocular irritation symptoms and other symptoms were 11. 6% and 3. 7% respectively. The detection rates of respiratory discomfort and skin symptoms in female workers exposed to CTP were higher than those in men (17. 2 vs 7. 6 and 20. 7 vs 5. 1%). The detection rate of ocular irritation symptoms in CTP workers was higher than that in non-drinking workers. Conclusion the early symptoms of health hazards to workers exposed to high levels of CTP include respiratory system. Skin and eye damage, gender and alcohol consumption may be factors.
