英文摘要: Environmental activity and health risk of heavy metals and PAHs in soil and dust will be studied in a typical smelting-coal power plant-coking plant industrial area. The concentrations of heavy metals and PAHs in the soil and dust samples will be analyzed by ICP-MS, AFS and GC-MS methods. The spatial distribution and spatial composition characteristics of heavy metals and PAHs in soil and dust will be analyzed by using RS and GIS methods on base of geostatistic results for announcing the relationship between soil and dust and the spatial varaition pattern. The environmental activity and interaction of heavy metals and PAHs in soil will be studied by BCR continous extraction and leaching experiments. The sources of heavy metals and PAHs in soil and dust will checked by the comprehensive analyzing of the results of isotope technology, multistatistic and spatial analyse. The health risk of heavy metals and PAHs in soil and dust to local residents will assessed using USEAP health risk assessment model on the study of expose parameters and expose ways. All the research results will provide scientific evidence for risk management and the environmental remediation of heavy metals and PAHs.
