污染场地不同深度土壤有机-矿质复合体中有机氯农药的分布
Organochlorine pesticides distribution in organo-mineral aggregates in different soil layers from a contaminated site
摘要
Abstract
Four different soil particle-size fractions, clay, silt, fine sand and coarse sand from the soils in an organochlorine pesticide (OCP) field, were separated by physical method to characterize the OCPs distribu- tion in soils and to study the effect of organic matter content in different organo-mineral aggregates on pollutants distribution. The results suggested that the concentration of HCHs in silt and DDTs in clay was higher than that in other organo-mineral aggregates. There was a significant correlationship between the contents of HCHs and DDTs and the organic matter in the clay and silt. However, the relationship was not significant in the fine and coarse sand. The results were in accordance with the analysis results between the values of lgKocand the content of the pollutants. The experimental data also showed that organic carbon may be one of the important factors for the distribution of OCPs in the soils of the studying field. The results of this study could provide the foundation for environmental remediation and the risk controlling of contaminated sites.关键词
