The occurrence and ecological risks of ten typical pharmaceutical and personal care products (PPCPs) at 12 typical inflow rivers of Taihu lake was investigated in this study. Seven out of the ten typical PPCPs targeted were detected in all the water samples and sediment samples tested. The PPCPs concentration detected were 0-94.91 ng/L for water samples and 0-18.27 ng/g for sediment samples. Sulfamethoxazole (SMZ) and erythromycin (ERY) has relatively higher concentration than other PPCPs in surface water samples, ciprofloxacin (CIP) and ofloxacin (OFX) has relatively higher concentration in the sediment samples. Inflow river-Caoqiao river has a relatively highest contamination of TN and TP, the PPCPs concentration in the river channel, estuary, lake-body also shows high value. This occurs in both the surface water and sediment sample, implied a relatively high pollution input from Caoqiao river. SMZ holds high long-term ecological risks in both surface water and sediment of almost all the tested inflow rivers of Taihu lake. Only ERY has medium short-term risks in surface water, other analyzed PPCPs hold low or insignificant short-terms risks for both surface water and sediments. This study fills the gap of PPCPs ecological risk of surface water and sediment of 12 typical inflow rivers of Taihu Lake, and revealed the importance of control sulfanilamide of the economic belt around Taihu Lake. The results of the present study are useful in providing information for PPCPs control and sustainable water management in freshwater lakes.
本研究调查了太湖 12 条典型入湖河流中 10 种典型药物和个人护理品（PPCPs）的发生情况及其生态风险。在所检测的所有水样和沉积物样品中，有 7 种目标 PPCPs 被检测到。检测到的 PPCPs 浓度范围为水样 0-94.91ng/L，沉积物 0-18.27ng/g。磺胺甲恶唑（SMZ）和红霉素（ERY）在地表水中的浓度相对较高，环丙沙星（CIP）和氧氟沙星（OFX）在沉积物中的浓度相对较高。入湖河流草桥河的 TN 和 TP 污染较为严重，河道、河口、湖体的 PPCPs 浓度也较高。这在地表水和沉积物样本中均有体现，表明草桥河的污染输入相对较高。SMZ 在太湖所有入湖河流的地表水和沉积物中均具有较高的长期生态风险。只有 ERY 在地表水中具有中等短期风险，其他分析的 PPCPs 在地表水和沉积物中均具有低或无显著短期风险。本研究填补了太湖 12 条典型入湖河流地表水和沉积物中 PPCPs 生态风险的空白，揭示了环太湖经济带磺胺类药物控制的重要性。本研究结果可为淡水湖泊中 PPCPs 控制和可持续水资源管理提供信息。
