    摘要:

    通过对杭州周边某设施蔬菜大棚基地的土壤采集分析和农田残留农膜的提取分析,结果表明该地区土壤存在一定程度的酞酸酯污染,污染程度与国内大部分农田土壤相当。农膜中酞酸酯含量和农膜类型对土壤酞酸酯含量均有一定得影响。农膜中酞酸酯含量和土壤中酞酸酯含量具有显著正相关性,长期覆盖的农膜与黑色农膜覆盖土壤的酞酸酯含量相对较高,因此减少残旧农膜在土壤中的残留是减少土壤酞酸酯污染的有效途径之一。大棚覆盖或地膜覆盖等不同农膜覆盖方式对土壤酞酸酯含量在本研究中没有发现有显著差异。土壤酞酸酯含量与土壤有机质极显著正相关,表明土壤有机质对酞酸酯特别是高分子量酞酸酯化合物在土壤中的环境行为有重要的作用。

    Abstract:

    The ubiquity of phthalate esters has been frequently reported in agricultural soils in China. Samples of soil and plastic film were collected in a plastic greenhouse field cultured with vegetables from suburb of Hangzhou city, Zhejiang Province. The results indicated that contamination of PAEs was occurred in the soil of local vegetable field and the degree of PAEs contamination was comparable to that found in most of other study areas in China. Content of PAEs in the plastic film have a positive impact on the content of PAEs in soil. Soil covered with aged plastic film or with the black film was observed containing high content of PAEs. Therefore, reduction of the aged plastic film residue in soil is a feasible way to decrease PAEs contamination in soil. No significantly difference was found among the different covering types (shed or mantled) of plastic film in present study. Significant positive correlation has been obtained between the content of PAEs and that of organic matter in soil, which is presumed that soil organic matter would be an important effects on the environmental fate of PAEs, in particular for the higher molecular PAEs such as DEHP.
