山东寿光设施菜地土壤-农产品邻苯二甲酸酯（PAEs）污染特征调查
Phthalate acid esters(PAEs)pollution in soils and agricultural products of vegetable greenhouses in Shouguang City, Shandong Province
摘要
Abstract
Phthalate acid esters(PAEs)are extensively used as plasticizers of plastic products. Therefore, these PAEs have accumulated in greenhouse soils. This study was conducted to understand PAEs pollution in soils and their enrichment in agricultural products from veg-etable greenhouses in Shouguang City, Shandong Province. Soil and agricultural product(cucumber)samples from 17 vegetable greenhouses were collected, and content of 6 PAE compounds as priority pollutants were determined by LC- MS/MS. The total content of these 6 PAEs (ΣPAEs)in soils ranged from 0.453 to 1.615 mg·kg-1, and the mean value was 1.197±0.361 mg·kg-1. DEHP and DBP were the main com-ponents of PAEs in the soils. DEHP accounted for 45%~77%ofΣPAEs, and DBP for 17%~44%. Based on the control standards of priority pollutants of PAEs(U. S. EPA), DBP content in all soil samples and DMP in 52%soil samples exceeded the control standards, implying that these soils had certain pollution risks.ΣPAEs content in soils did not show significant correlation with age of vegetable greenhouses.The ΣPAEs content was the highest in the fifth year of planting, and changed little after that.ΣPAEs had a significant positive correlation with DBP, DEHP, organic matter and CEC content, but significantly negatively correlated with pH. ΣPAEs content in cucumbers ranged from 0.42 to 1.62 mg·kg-1, averaging 1.09 mg·kg-1. The mean enrichment coefficient was 1.02. DEHP and DBP were the main components in cucumbers, accounting for 53%~97%of ΣPAEs. Generally, the levels of PAEs in agricultural products were lower than the suggested standards in USA and Europe, implying a comparatively low health risk.关键词
