| 英文摘要 | Topsoil samples from 56 sites around the guanting reservoir, china, were measured for hch and ddt concentrations. the total soil hch content (including alpha-, ss-, gamma-, and delta-isomers) in these soil samples ranged from 0 to 7.33 ng.g - 1 , with a mean of 0.69 ng.g(-1) . these levels were considerably lower than those of the total ddt soil contents (including pp'-dde, pp'-ddd, op'-ddt, and pp'-ddt), which ranged from 0 to 76.01 ng.g(-1) , with a mean of 9.46 ng.g(-1) . ddt was also found to be the major pollutant in the soil samples, accounting for similar to 93% of the total organochlorine pesticide (ocp) contents. several environmental factors including land use, soil texture, soil taxonomy, and microbial biomass were considered to be responsible for the ocp levels observed. the data provide some insight into the effects of environmental conditions such as soil formation, agricultural cultivation, nutrient enrichment, and other anthropogenic activities on the degradation of ocps in soils. although the ocp residues currently are below the maximum limits set for use on agricultural land in china, and only rarely would such levels pose significant ecological concern, ocps are highly persistent in soil and bioaccumulative. the data provided in this study are considered crucial for reservoir remediation, especially since the guanting reservoir will serve as one of the main drinking water sources for beijing in the foreseeable future. |
