目的了解加油站空气中铅尘水平,为加油站工人健康监护提供科学依据。方法选择张家港市10家加油站,设30个采样点采集空气样品进行铅尘测定,并与非加油站区域进行对比。结果加油站空气中铅尘含量均值为(4.2±0.8)μg/m3,对照组为(2.1±0.4)μg/m3,差异有统计学意义(t=0.138,P<0.01),铅含量均未超过国标,但个别加油站监测铅尘含量已接近国标。结论应加强加油站铅尘含量监测及工人健康监护。
Objective To understand the level of lead and dust in the air of gas stations and provide a scientific basis for the health monitoring of workers in gas stations. Methods Ten gas stations in Zhangjiagang City were selected. Air samples were collected from 30 sampling points for lead dust determination and compared with non-gas station areas. Results The average leaded dust content in the air at the gas station was (4.2 ± 0.8) μg / m3 and in the control group was (2.1 ± 0.4) μg / m3, the difference was statistically significant (t = 0.138, P <0.01) More than the national standard, but individual gas stations to monitor lead dust content is close to the national standard. Conclusion Monitoring of lead dust at gas stations and worker health monitoring should be strengthened.
