目的了解洗煤厂作业工人的健康状况。方法选择某洗煤厂粉尘及噪声作业工人592名作为接触组,另选择某甲醇厂作业工人362名作为对照组,对高千伏X射线胸片、电测听、心电图及血压检查结果进行对照分析。结果接触组胸片异常率为13.2%,听力损失率为41.4%,心电图异常率为32.3%,血压升高率为30.1%,均明显高于对照组,2组资料经统计学检验,差异均有统计学意义(P<0.01) 洗煤厂粉尘及噪声对作业工人健康有明显损害,且噪声危害程度随工龄的升高有加重的趋势。
Objective To understand the health status of workers in coal washing plants. Methods 592 dust and noise workers in a coal washing plant were selected as the contact group, and 362 workers in a methanol plant were selected as the control group. The results of high kV X-ray, electric audiometry, electrocardiogram and blood pressure examination were compared . Results The abnormal rate of chest radiograph in contact group was 13.2%, hearing loss rate was 41.4%, electrocardiogram abnormality rate was 32.3% and blood pressure increased rate was 30.1%, which were significantly higher than those in control group. The two groups of data were statistically tested, the differences were There was statistical significance (P <0.01). The dust and noise of coal washing plant had a significant damage to the health of workers, and the degree of noise hazard tended to increase with the increase of seniority.
