目的了解长期接触低剂量汞蒸气对工人肾小管功能的影响。方法收集某光源生产企业接触汞作业工人尿液,检测其汞水平、尿中β2-微球蛋白(β2-MG)水平;并收集该厂2004—2009年汞作业工作场所空气中汞质量浓度资料。结果车间空气中汞时间加权平均浓度(TWA)为0.001~0.007 mg/m3,短时间接触浓度(STEL)为0.001~0.008mg/m3,将接触汞工人工龄(分为<5年和≥5年)与尿汞水平、尿β2-MG水平进行相关性分析,发现工龄与尿汞水平、尿β2-MG水平之间,尿汞水平和尿β2-MG之间均无明显相关性(P>0.05)。结论在工作场所汞蒸气质量浓度低于国家规定卫生标准的情况下,长期接触汞对工人的肾小管功能尚未发现明显影响。
Objective To understand the effect of long-term exposure to low-dose mercury vapor on renal tubular function in workers. Methods Urine was collected from workers exposed to mercury in a light source manufacturing enterprise to detect the level of mercury and the level of β2-microglobulin (β2-MG) in urine. The mercury concentration in the air of workplace mercury from 2004 to 2009 was collected . Results The weighted average concentration of mercury in workplace air was 0.001-0.007 mg / m3 and the STEL was 0.001-0.008 mg / m3. The average working hours of mercury workers (<5 years and ≥5 years ) And urinary mercury levels, urinary β2-MG levels were analyzed and found no correlation between length of service and urine mercury levels, urinary β2-MG levels, urinary mercury levels and urine β2-MG (P> 0.05 ). Conclusions Long-term exposure to mercury has not been found to have any significant effect on the renal tubular function of workers in the workplace where the mercury vapor concentration is below the nationally prescribed hygienic standard.
