饮用水中邻苯二甲酸酯类的调查

An Investigation on Phthalates in Drinking Water

为了解邻苯二甲酸酯类对水质的污染情况，对浙江省１０ 个水厂的源水和出厂水进行色谱分析，每个水厂均检出邻苯二甲酸酯类。其中１０ 个水厂检出邻苯二甲酸二丁酯，最高含量达０－０７６ ｍｇ／Ｌ。５ 个水厂检出邻苯二甲酸二（２乙基己基） 酯，最高含量为０－０１７ ｍ ｇ／Ｌ。未检出邻苯二甲酸二甲酯、邻苯二甲酸二乙酯、邻苯二甲酸丁基苄酯。提示水体中的邻苯二甲酸酯类污染物目前以邻苯二甲酸二丁脂、邻苯二甲酸二（２乙基己基）

To explore the kinds and levels of phthalates pollutants in water,the water samples of source water and treated water collected from 10 water plants were detected by gas chromatography technique in Zhejiang province.The results showed that phthalate compounds were found in water samples from every water plant,the maximum level of which was noticed in this component-di n butyl phthalate,and reached to 0.076 mg/L.Di(2 ethylhexyl)phthalate were found in water samples collected from 5 water plants,the maximum levels of which reached to 0.017 mg/L.Di methyl phthalate,di ethyl phthalate and butyl benzyl phthalate were not found in any water sample.It indicated that the main pollutants of phthalates were di n butyl phthalate and di(2 ethylhexyl)phthalate in water body.
