为了解舟山市嵊泗县某体温计制造厂的汞污染情况。收集该企业2007—2011年职业病危害因素监测及作业人员职业健康检查结果,分析汞污染浓度、作业人员尿汞含量。结果显示,该厂汞浓度明显超标,且超标的监测点数较多,超标率77.3%,车间治理前后分别超标80.8%、73.3%,治理后车间总体平均浓度有所下降(t=2.81,P<0.01);员工尿汞超标率分别为95.2%、89.3%,治理前后无明显差异(P>0.05);一线作业工人的尿汞平均值高于二线作业区(P<0.01)。提示,该厂作业环境经治理后汞浓度有明显降低,但仍对作业工人健康有很大的影响,应需要进一步加大治理措施,加强职业卫生防护,保护作业人员的身体健康。
To understand the mercury pollution in a thermometer manufacturing plant in Shengsi County, Zhoushan City. Collecting the monitoring of occupational hazards and occupational health examination results of the enterprise from 2007 to 2011, analyzing the concentration of mercury pollution and urinary mercury content of workers. The results showed that the mercury concentration in the plant exceeded the standard obviously and exceeded the standard by 77.3%. The plant average exceeded the standard by 80.8% and 73.3% before and after the plant management, respectively. The average concentration of the plant decreased after treatment (t = 2.81, P < 0.01). The over standard rate of urinary mercury in staff was 95.2% and 89.3% respectively, there was no significant difference before and after treatment (P> 0.05). The average urinary mercury in front line workers was higher than that in second line work area (P <0.01). It is suggested that the mercury concentration in the operating environment of the plant has been significantly reduced after its treatment, but it still has a great impact on the health of workers. It is necessary to further increase the control measures, strengthen occupational health protection and protect the health of workers.
