桂林市农村土壤中酞酸酯类污染抽样分析

选择桂林市灵川县大圩镇吕岸村、阳朔县白沙镇凉水井村、兴安县溶江镇莲塘村3个村庄,进行土壤中6种酞酸酯邻苯二甲酸二（2-乙基已基）酯（DEHP）、邻苯二甲酸丁基苄酯（BBP）、邻苯二甲酸二正丁酯（DBP）、邻苯二甲酸二正辛酯（DOP）、邻苯二甲酸二乙酯（DEP）、邻苯二甲酸二甲酯（DMP）]的调查分析.结果显示,各类监测点DEHP含量的平均值比邻苯DBP高;酞酸酯浓度范围为0.001～1.168 mg/kg;总酞酸酯浓度平均值依次为凉水井村农田＞凉水井村菜地＞莲塘村葡萄园＞凉水井村柚子园＞凉水井村金桔园＞吕岸村菜地.这表明,酞酸酯类对环境已经产生影响,应引起足够关注.

Investigation on Phthalate Esters Pollution of Soil in Part Rural Areas in Guilin

Lvan village in Daxu town of Lingchuan county, Lingshuijing village in Baisha town of Yangshuo county, and Liantang village in Rongjiang town of Xingan county, three natural villages in Guilin were chosen to investigate and analyze 6 phthalate esters in soil. The re- suits show that the average concentration of DEHP in all monitoring sites is higher than the average concentration of DBP, with the total concentration of phthalate esters ranging from 0. 001 mg/kg to 1. 168 mg/kg. The order of monitoring sites （from high to low in terms of total concentration of phthalate esters） is： farmland in Liangshuijing village, vegetable plot in Liangshuijing village, vineyard in Liantang village, grapefruit garden in Liangshuijing vil- lage, kumquat garden in Liangshuijing village and vegetable plot in Lvan village, which indi- cates the effects of phthalate esters on the environment and enough attention should be aris- eno
