Pharmaceutical and personal care products (PPCPs), including antibiotics, azole anti-fungals, non-steroid anti-inflammatory drugs, lipid regulators, parabens, antiseptics, and bisphenol A, were investigated in groundwater and reservoirs in the vicinity of two municipal landfills in the metropolis of Guangzhou, South China. Dehydroerythromycin, sulfamethoxazole, fluconazole, salicylic acid, methylparaben, triclosan, and bisphenol A were the mostly frequently detected PPCPs in the groundwater at low ng L(-1) levels. In the reservoirs, the PPCPs were widely detected at higher frequencies and concentrations, especially sulfamethoxazole, propiconazole, and ibuprofen, with maximal concentrations above 1 μg L(-1). The PPCPs in the groundwater did not show significant seasonal differences or spatial trends. However, in the reservoirs, higher PPCP concentrations were observed in spring than in other seasons. The anti-bacterials in the groundwater posed medium risks to algae. In the reservoirs, the sulfonamides and macrolides posed low to high risks, while ibuprofen, salicylic acid, and clofibric acid presented low to medium risks to aquatic organisms. Overall, the results showed that the PPCP contaminants and subsequent ecological risks in the groundwater and surface water in the vicinity of the landfills may be of serious concern. More research is needed to better correlate the landfill leachates and PPCP contamination in the nearby aquatic environments.
药品和个人护理产品（PPCPs），包括抗生素、唑类抗真菌药、非甾体抗炎药、脂质调节剂、对羟基苯甲酸酯、防腐剂和双酚 A，在中国南方大都市广州的两个市垃圾填埋场附近的地下水和水库中进行了调查。在地下水环境中，以低纳克每升（ng/L）水平存在的最常见的 PPCPs 是去羟红霉素、磺胺甲恶唑、氟康唑、水杨酸、甲基对羟基苯甲酸酯、三氯生和双酚 A。在水库中，PPCPs 的检出频率和浓度更高，尤其是磺胺甲恶唑、丙环唑和布洛芬，最高浓度超过 1 微克每升（μg/L）。地下水中的 PPCPs 没有表现出明显的季节性差异或空间趋势。然而，在水库中，春季的 PPCP 浓度高于其他季节。地下水中的抗菌剂对藻类构成中等风险。在水库中，磺胺类和大环内酯类抗生素对水生生物的风险为低至高，而布洛芬、水杨酸和氯菲酸对水生生物的风险为低至中。总体而言，研究结果表明，垃圾填埋场附近地下水和地表水的 PPCP 污染物及其随后的生态风险可能令人严重关切。需要进一步研究，以更好地将垃圾渗滤液与附近水生环境中的 PPCP 污染相关联。
