Abstract

Estrogens in river systems can significantly impact aquatic ecosystems. This study aimed to investigate the multiphase partitioning of estrogens in Wulo Creek, Taiwan, which receives animal feedlot wastewater, to understand their distribution and potential environmental implications. Water samples were separated into suspended particulate matter (SPM), colloidal, and soluble phases using centrifugation and cross-flow ultrafiltration. Concentrations of estrone (E1), 17β-estradiol (E2), and estriol (E3) in each phase were analyzed using LC/MS/MS. Partition coefficients were calculated to assess estrogen distribution among phases. Estrogens were predominantly found in the soluble phase (85.8-87.3%). The risk assessment of estrogen equivalent (EEQ) values suggests that estrogen concentration in water poses a higher risk compared to SPM, with a majority of the samples indicating a high risk to aquatic organisms. The colloidal phase contained 12.7-14.2% of estrogens. The log KCOC values (4.72-4.77 L/kg-C) were significantly higher than the log KOC and log KPOC values (2.02-3.40 L/kg-C) for all estrogens. Colloids play a critical role in estrogen distribution in river systems, potentially influencing their fate, transport, and biotoxicity. This finding highlights the importance of considering colloidal interactions in assessing estrogen behavior in aquatic environments.

受饲养场废水排放影响的河流中雌激素的多相分离。
河流系统中的雌激素会对水生生态系统产生重大影响。本研究旨在调查台湾乌螺溪中雌激素的多相分配情况,以了解雌激素在乌螺溪中的分布及其对环境的潜在影响。研究采用离心法和错流超滤法将水样分离成悬浮颗粒物(SPM)、胶体和可溶相。采用 LC/MS/MS 分析了每一相中雌酮(E1)、17β-雌二醇(E2)和雌三醇(E3)的浓度。通过计算分配系数来评估雌激素在各相之间的分布情况。雌激素主要存在于可溶相中(85.8-87.3%)。雌激素当量(EEQ)值的风险评估表明,与 SPM 相比,水中的雌激素浓度具有更高的风险,大多数样本表明对水生生物具有高风险。胶体相含有 12.7-14.2% 的雌激素。所有雌激素的对数 KCOC 值(4.72-4.77 升/千克-碳)都明显高于对数 KOC 和对数 KPOC 值(2.02-3.40 升/千克-碳)。胶体对雌激素在河流系统中的分布起着至关重要的作用,可能会影响雌激素的归宿、迁移和生物毒性。这一发现强调了在评估雌激素在水生环境中的行为时考虑胶体相互作用的重要性。

期刊介绍: The Journal accepts papers describing work that furthers our understanding of the exposure, effects, and risks of chemicals and materials in humans and the natural environment as well as approaches to assess and/or manage the toxicological and ecotoxicological risks of chemicals and materials. The journal covers a wide range of toxic substances, including metals, pesticides, pharmaceuticals, biocides, nanomaterials, and polymers such as micro- and mesoplastics. Toxics accepts papers covering: The occurrence, transport, and fate of chemicals and materials in different systems (e.g., food, air, water, soil); Exposure of humans and the environment to toxic chemicals and materials as well as modelling and experimental approaches for characterizing the exposure in, e.g., water, air, soil, food, and consumer products; Uptake, metabolism, and effects of chemicals and materials in a wide range of systems including in-vitro toxicological assays, aquatic and terrestrial organisms and ecosystems, model mammalian systems, and humans; Approaches to assess the risks of chemicals and materials to humans and the environment; Methodologies to eliminate or reduce the exposure of humans and the environment to toxic chemicals and materials.
