摘要

摘要: 对福州市晋安湖不同点位的上覆水及沉积物中营养盐和抗生素开展了一年监测,重点解析了传统污染物与新污染物引起的时空分布差异,对其引起的生态风险进行了评价。研究结果显示,湖体上覆水总氮浓度全年维持在较高水平(1.88~4.96 mg/L),而总磷在夏季表现出较高的浓度水平(0.15~0.55 mg/L),湖体在夏季呈现中度富营养状态(TLI值介于59.92~66.34)。湖体沉积物总氮含量为30.0~1780.0 mg/kg,总磷含量为81.4~2585.0 mg/kg,显示为中度或重度的富营养化污染。上覆水、沉积物中检测到5种抗生素(磺胺甲噁唑、四环素、磺胺多辛、磺胺林、土霉素)的浓度范围分别为0.49~13.03 ng/L、0.23~4.80 ng/g,抗生素的浓度及生态风险在冬季高于其他季节。针对城市人工湖可能同时存在的富营养化风险和生态风险,需要考虑常规污染物与新污染物的时间、空间分布特征,选择更为有效的技术对关键点位存在的复合污染进行针对性治理。

Abstract: This study implemented a comprehensive one-year monitoring program to assess the levels of nutrients and antibiotics in both surface water and sediments across diverse locations within Jin'an Lake in Fuzhou. The investigation was primarily directed towards scrutinizing the nuanced spatiotemporal variations induced by conventional pollutants and emerging contaminants, coupled with evaluating the associated ecological risks. The findings unveiled that the total nitrogen concentration in the lake's surface water consistently maintained an elevated status throughout the year(1.88 to 4.96 mg/L), while total phosphorus exhibited heightened concentration during the summer(0.15 to 0.55 mg/L), indicating a state of moderate eutrophication(with a trophic level index ranging from 59.92 to 66.34) during this season. The sediment analysis indicated a total nitrogen content ranging from 30.0 to 1780.0 mg/kg and a total phosphorus content ranging from 81.4 to 2585.0 mg/kg, signifying a condition of moderate to severe eutrophication pollution level. Notably, five antibiotics(sulfamethoxazole, tetracycline, sulfadimoxine, sulfamethoxymethane, and tylosin) were discerned in both surface water and sediments, exhibiting concentrations spanning from 0.49 to 13.03 ng/L and 0.23 to 4.80 ng/g, respectively. The concentrations of antibiotics and associated ecological risks manifested a seasonal disparity, with higher levels observed in winter than in other seasons. Considering the potential co-occurrence of eutrophication and ecological risk within urban artificial lakes, prudent consideration of the spatiotemporal distribution characteristics of conventional pollutants and emerging contaminants is imperative. Moreover, the judicious selection of more productive technologies for the targeted remediation of composite pollution at critical sites emerges as a critical imperative.
