巢湖水中邻苯二甲酸酯安全性评价

Safety Evaluation on Five Kinds of PAEs in Chaohu Lake

本文测定了5种PAEs在巢湖水中的质量浓度,邻苯二甲酸二甲酯、邻苯二甲酸二乙酯、邻苯二甲酸二丁酯和邻苯二甲酸二异辛酯在所有采样点位均有检出,邻苯二甲酸二甲酯的最高质量浓度为3.15μg/L、邻苯二甲酸二乙酯的最高质量浓度为1.82μg/L、邻苯二甲酸二丁酯的最高质量浓度为12.95μg/L,邻苯二甲酸二异辛酯最高为7.21μg/L,未检出邻苯二甲酸二正辛酯。运用数学模型对PAEs在水中的环境行为进行了安全性评价,结果显示巢湖水受到邻苯二酸酯不同程度的污染。

Five kinds of phthalates pollutants were detected in Chaohu water. Results showed that phthalate esters were found in every water samples, the maximum level of Di-methyl phthalate, di-ethyl phthalate, di- n- butyl phthalate, di （2 - ethyhexyl） phthalate reached 3.15 μg/L, 1.82 μg/L, 12.95 μg/L, 7.21 μg/L respectively. Di-n-octyl phthalate were not found in any water sample. The safety of environment behavior of phthalates pollutants were evaluated by mathematical model. Chaohu water was polluted by phthalate esters in different degree.
