| 中文摘要 |
| 采用固相萃取-超高效液相色谱-串联质谱法（SPE-UPLC-MS/MS）分析了骆马湖及主要入湖河流表层水体中磺胺类（SAs）、喹诺酮类（QUs）、四环素类（TCs）、大环内酯类（MLs）和青霉素类（PLs）这5类39种抗生素的浓度水平，分析了主要入湖河流的污染贡献率，并评价了抗生素潜在的生态与健康风险.结果表明，42个采样点ρ（抗生素）范围为30.10~582.37 ng·L-1，共检出4类23种抗生素，其中恩诺沙星（ERX）平均检出浓度最高（88.05 ng·L-1），林可霉素（LIN）检出率最高（100%）.骆马湖北部的抗生素平均值高于南部，且两条主要入湖河流中，沂河是骆马湖主要的抗生素污染贡献河流，贡献率为53.91%.风险评价结果表明，ERX具有最大的风险商，对于联合风险商（RQcum），除了L6、R30、R31、R32、R33和R42这6个点的RQcum处于0.1~1之间，属于中等风险，其他点位均RQcum>1，属于高风险；对11种抗生素进行健康风险评价，成人和儿童的健康风险商（RQH）处于4.16×10-6~2.46×10-3之间，对人体无健康风险. |
| 英文摘要 |
| The concentration levels of 39 antibiotics, including sulfonamides (SAs), quinolones (QUs), tetracyclines (TCs), macrolides (MLs), and penicillins (PLs), in the surface water of Luoma Lake, and its main inflow rivers were analyzed using SPE-UPLC-MS/MS. The contribution rates of pollution of major rivers entering the lake were analyzed, and the potential ecological and health risks of antibiotics were assessed. The results showed that ρ(antibiotics)in 42 sampling sites was between 30.10 ng·L-1 and 582.37 ng·L-1, and a total of four classes of 23 antibiotics were detected. Among them, the average detection concentration of enrofloxacin (ERX) was the highest (88.05 ng·L-1), and the detection rate of lincomycin (LIN) was the highest (100%). The average concentration of antibiotics in the northern region of Luoma Lake was higher than that in the south, and among the two main rivers entering the lake, Yihe River was the main river contributing to the pollution of antibiotics in Luoma Lake, with a contribution rate of 53.91%. The results of risk assessment showed that ERX had the largest risk quotient. For the cumulative risk quotient (RQcum), RQcum of L6, R30, R31, R32, R33, and R42 was between 0.1 and 1, which is considered medium risk, and RQcum of other points was>1, which is considered high risk. The health risk assessment of 11 antibiotics showed that the health risk quotient (RQH) of adults and children ranged from 4.16×10-6 to 2.46×10-3, and there was no health risk to the human body. |
