Abstract：
The extensive use of the parabens triclosan (TCS) and bisphenol A (BPA) has potential adverse effects on human health and aquatic organisms. However, their monitoring information in freshwater lakes is still limited. This study simultaneously summarized the concentrations, spatial distribution characteristics, and correlations of four types of parabens, TCS, and BPA in the surface water and sediment of Baiyang Lake. Finally, the potential risks of target pollutants were evaluated from two aspects: human health risks and ecological risks. The average contaminations of target compounds in surface water and sediment-BPA, TCS, and ∑4 parabens-was 33.1, 26.1, 0.7 ng/L and 24.5, 32.5, 2.5 ng/g, respectively. The total concentration of target compounds at the inlet of the upstream Fu River and Baigouyin River is significantly higher than that near Hunan and the outlet. In addition, Spearman\'s correlation analysis showed a significant positive correlation between compounds. The health hazards of target compounds in surface water were all within safe limits. However, the risk quotient results indicate that in some locations in surface water, TCS poses a high risk to algae and a moderate risk to invertebrates and fish, and appropriate attention should be paid to these areas.
摘要：
对羟基苯甲酸酯三氯生（TCS）和双酚A（BPA）的广泛使用对人类健康和水生生物具有潜在的不利影响。然而,他们在淡水湖的监测信息仍然有限。本研究同时总结了浓度，空间分布特征，以及四种对羟基苯甲酸酯的相关性，TCS,白洋湖地表水和沉积物中的BPA。最后,从人体健康风险和生态风险两个方面对目标污染物的潜在风险进行了评价。地表水和沉积物中目标化合物的平均污染-BPA，TCS,对羟基苯甲酸酯为33.1、26.1、0.7ng/L和24.5、32.5、2.5ng/g，分别。上游傅河和白沟银河入口处的目标化合物总浓度明显高于湖南附近和出口。此外,Spearman相关分析显示化合物间呈显著正相关。目标化合物在地表水中的健康危害均在安全范围内。然而,风险商结果表明，在地表水的某些位置，TCS对藻类构成高风险，对无脊椎动物和鱼类构成中等风险，应该适当注意这些领域。
