To evaluate the distributions and health risks of phthalate esters in the main source water and corresponding drinking water of Zhejiang Province, the concentrations of 16 phthalate esters in water samples from 19 sites were measured from samples taken in the dry season and wet season. The concentration of the total phthalate ester congeners in source water ranged from 1.07 μg/L to 7.12 μg/L in the wet season, from 0.01 μg/L to 1.58 μg/L in the dry season, from 1.18 μg/L to 15.28 μg/L from drinking water in the wet season, and from 0.16 μg/L to 1.86 μg/L from drinking water in the dry season. Of the 16 phthalate esters, dimethyl phthalate, dibutyl phthalate, di-(2-ethyl-hexyl) phthalate, di-iso-butyl phthalate, bis-2-n-butoxyethyl phthalate, and dicyclohexyl phthalate were present in the samples analyzed, dominated by di-iso-butyl phthalate and di-(2-ethyl-hexyl) phthalate. The concentrations of phthalate esters in the wet season were all relatively higher than those in the dry season, and the drinking water had higher concentrations of phthalate esters than source water. The phthalate ester congeners studied pose little health risk to nearby citizens. Environ Toxicol Chem 2015;34:2205-2212. © 2015 SETAC.
为评估浙江省主要水源水及相应饮用水中邻苯二甲酸酯的分布情况和健康风险，采集了19个采样点在枯水期和丰水期的水样，测定了其中16种邻苯二甲酸酯的浓度。丰水期水源水中邻苯二甲酸酯类同系物的总浓度范围为1.07μg/L至7.12μg/L，枯水期为0.01μg/L至1.58μg/L；丰水期饮用水中邻苯二甲酸酯类同系物的总浓度范围为1.18μg/L至15.28μg/L，枯水期为0.16μg/L至1.86μg/L。在所分析的样品中检测到了16种邻苯二甲酸酯中的邻苯二甲酸二甲酯、邻苯二甲酸二丁酯、邻苯二甲酸二（2-乙基己基）酯、邻苯二甲酸二异丁酯、邻苯二甲酸二（2-正丁氧基乙基）酯和邻苯二甲酸二环己酯，其中以邻苯二甲酸二异丁酯和邻苯二甲酸二（2-乙基己基）酯为主。邻苯二甲酸酯在丰水期的浓度均相对高于枯水期，且饮用水中邻苯二甲酸酯的浓度高于水源水。所研究的邻苯二甲酸酯类同系物对附近居民的健康风险较小。《环境毒理学与化学》2015年；34：2205 - 2212。© 2015 SETAC。
