为调查养路工铅危害现状并采取相应对策,采用现场调查、养路工健康体检和综合分析法等进行评价。结果表明,宝鸡市路边的铅浓度由高至低依次为山区公路(秦岭)、市区城镇道路及平原公路,平均浓度分别为1.8、1.5和1.3μg/m3,远离公路的乡村(对照)铅浓度仅0.3μg/m3。392名养路工血铅检测结果均值为76.56μg/L。山区凤县、太白县公路段养路工血铅平均值明显高于其他县区,最高达150.38μg/L。最低为麟游县公路段养路工(血铅平均值为39.06μg/L)。提示,养路工体内血铅水平与接触汽车尾气密切相关。铅是养路工职业病危害因素之一,要重视防治工作。
In order to investigate the status quo of road maintenance workers’ lead hazards and to take appropriate countermeasures, field surveys, road health check-ups and comprehensive analysis methods were used to evaluate them. The results showed that the lead concentrations in the roadsides of Baoji City from high to low were mountain road (Qinling), urban road and plains highway in urban areas with average concentrations of 1.8, 1.5 and 1.3μg / m3 respectively, Lead concentration of only 0.3μg / m3.392 road maintenance work blood lead test results were 76.56μg / L. The average blood lead level of road maintenance workers in Feng County and Taibai County was significantly higher than those in other counties, up to 150.38 μg / L. The lowest for Linyou highway maintenance workers (average blood lead 39.06μg / L). Tip, road maintenance workers in the body of lead levels in contact with vehicle exhaust are closely related. Lead is one of the hazards of road maintenance workers occupational diseases, should pay attention to prevention and control work.
