通过监测湖南某典型铅锌锰冶炼区大气总悬浮颗粒物(TSP)和铅锌冶炼企业外排废气中Cd、Cr、As、Ni、Pb、Zn、Cu和Mn的浓度水平,应用富集因子、相关性及主成分分析研究了铅锌冶炼企业外排废气中重金属含量与大气TSP中重金属含量的关系,采用美国环境保护署(USEPA)的人体暴露风险评价模型进行了健康风险评价.结果 表明:废气中重金属平均浓度表现为Zn＞Cr＞Mn＞Cu＞Ni＞Pb＞Cd＞As.其中,致癌物质Cd、Cr、As、Ni的平均质量浓度分别为4.87、27.06、0.09、12.54 μg/m3,非致癌物质Pb、Cu、Zn、Mn的平均质量浓度分别为5.87、17.98、10 426.87、23.52 μg/m3.大气TSP中重金属平均浓度表现为Zn＞C u＞ Pb＞...

Concentration levels of Cd,Cr,As,Ni,Pb,Zn,Cu and Mn in the atomspheric TSP and exhaust gas of a Pb-Zn smelting enterprise were monitored in a typical Pb-Zn-Mn smelting area in Hunan. Enrichment factor,correlation and principal component analysis were used to study the relationship between the content of heavy metal in the exhaust gas and that in the atmospheric TSP. The US Environmental Protection Agency (USEPA) human exposure risk assessment model was adopted to conduct the health risk assessment. Results showed that mean mass concentrations i...
