%X 采用原子吸收分光光度法测定分析对比空气质量良好和重污染天气情况下的空气中7种重金属元素含量&#65292;并对比四种不同条件下两种空气样本中的重金属含量。本研究以天津市某地区环境空气为研究对象&#65292;选取空气质量良好和重污染天气两种样本&#65292;测定了环境空气中铜、锌、铅、镉、铬镍和锰7种重金属的含量&#65292;结果表明&#65292;重污染天气情况下环境空气中重金属含量比天气良好状态下含量高&#65292;且秋季重污染天气最为严重&#65307;由于特殊的产业结构和机动车尾气排放&#65292;元素Pb的含量增加尤为明显&#65292;Cd和Cr具有潜在的致癌风险&#65292;政府和相关部门应更关注重金属污染物的排放与监测。<br>Using atomic absorption spectrophotometry to determine and compare the content of seven heavy metal elements in the air under good air quality and heavy pollution weather conditions, and comparing the content of heavy metals in two air samples under four different conditions. This study takes the ambient air in a certain area of Tianjin City as the research object, selects two samples of good air quality and heavy pollution weather, and measures the content of seven heavy metals including copper, zinc, lead, and chromium in the ambient air. The results show that the content of heavy metals in the ambient air is higher under heavy pollution weather conditions than under good weather conditions, and heavy pollution weather is most severe in autumn; Due to the special industrial structure and vehicle exhaust emissions, the content of element Pb has increased significantly, while Cd and Cr have potential carcinogenic risks. The government and relevant departments should pay more attention to the emission and monitoring of heavy metal pollutants.
