摘要 目的探讨聚氯乙烯(PVC)贴胶厂接触职业病危害因素对作业工人健康的影响程度。方法选择佛山市三水区某PVC贴胶厂的接触职业病危害因素的76名工人为接触组,以非接触职业病危害因素的25名工人为对照组,进行职业健康检查,并对工作场所1—2二氯乙烷浓度进行测定。结果1-2二氯乙烷短时间接触容许浓度(PC—STEL)超标率41.67%,超标最高的达24.1倍;噪声强度超标率41.67%,最高超过国家职业接触限值15.5dB(A);甲苯PC—STEL均在职业接触限值范围内。1-2二氯乙烷中毒检出率2.63%(1/38),禁忌证检出率5.26%(2/38)。噪声组听力损失检出率(57.41%)明显高于对照组(12.50%),差异有统计学意义(P〈0.001);听力损失检出率随接触噪声工龄的增加而升高(P〈0.05)。噪声作业禁忌证检出率3.70%(1/27)。甲苯作业工人血常规异常率10.53%(4/38)。结论PVC贴胶厂1—2二氯乙烷、甲苯、噪声对作业工人健康危害较大,应加强预防控制工作。 Objective To study the effect of exposure to occupation hazards on health in workers at a polyvinyl chloride ( PVC ) paste glue plant. Methods 76 workers exposing to occupation hazards at a PVC paste glue plant in Sanshui area were assigned to exposure groul 25 workers who did not expose to the hazards were assigned to control group. A survey on occupational health was conducted. The concentration of 1, 2-dichloroethane in the workplace was detected. Results The occupational exposure limits ( OELs ) rate of permissible concentration-short term exposure limit ( PC-STEL ) for 1, 2-dicholorethane was 41.67%. The OELs rate for noise intensity was 41.67%. The PC-STEL of toluene ranged in the OELs. The detection rate of 1, 2-dicholorethane poisoning was 2.63% ( 1/38 ), and the incidence of occupational contraindication exposed to 1, 2-dicholorethane was 5.26% ( 2/38 ). The incidence rate of hearing loss was significantly higher in the noise-exposure group than in control group ( 57.41% vs. 12.50%, P〈 0.001 ). The detection rate of hearing loss increased as the length of service prolonged ( P〈 0.05 ). The detection rate of occupational contraindication exposed to noise was 3.70% ( 1/27 ). The rate of abnormal routine blood test was 10.53% ( 4/38 ). Conclusions Prevention measures should be strengthened to control the levels of 1-2 dicholorethane, toluene, and noise, which are harmful to workers at PVC paste glue plants.
