Phthalate esters in main source water and drinking water of Zhejiang Province (China): Distribution and health risks

0
To evaluate the distributions and health risks of phthalate esters (PAEs) in the main source water and corresponding drinking water of Zhejiang Province, the concentrations of 16 PAEs in water samples from 19 sites were measured from samples taken in the dry season and wet season. The concentration of the total PAE congeners (ΣPAEs) 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 PAEs, di‐methyl phthalate (DMP), di‐butyl phthalate (DBP), di‐(2‐ethyl‐hexyl) phthalate (DEHP), di‐iso‐butyl phthalate (DIBP), bis‐2‐n‐butoxyethyl phthalate (DBEP) and di‐cyclohexyl phthalate (DCHP) were present in the samples analyzed, dominated by DIBP and DEHP. The concentrations of PAEs in the wet season were all relatively higher than those in the dry season, and the drinking water had higher concentrations of PAEs than source water. The PAE congeners studied pose little health risk to nearby citizens. This article is protected by copyright. All rights reserved
