Abstract
Release of domestic sewage leads to accumulation of xenoestrogens in holding waters, especially in closed or semi-enclosed waters such as lakes. In the study, the occurrence, distribution, estrogenic activity and risk of eight xenoestreogens were evaluated in Lake Donghu, China. Nonylphenol (NP), octylphenol (OP), and bisphenol A (BPA) were identified as the main xenoestrogens ranging from tens of ng Lâ1 (in the surface water) or ng gâ1 dw (in the suspended particles and sediment) to tens of μg Lâ1 or μg gâ1 dw. The sum of 17β-estradiol equivalents (âEEQs) ranged from 0.32 to 45.02 ng Lâ1 in the surface water, 0.53 to 71.86 ng gâ1 dw in the suspended particles, and 0.09 to 24.73 ng gâ1 dw in the sediment. Diethylstilbestrol (DES) was determined as the main contributor to âEEQs followed by NP. The risk assessment showed a higher risk in the surface water than in the suspended particles and sediment in such domestic sewage-holding lake.
