中文摘要
      为了解淮河下游湖泊(洪泽湖和高邮湖)表层水和沉积物中药品及个人护理品(PPCPs)的赋存特征及生态风险,采集了23个采样点的43个表层水和沉积物样品,检测了样品中的61种PPCPs,分析了洪泽湖和高邮湖PPCPs的浓度水平空间分布,计算了典型PPCPs在研究区水/沉积物系统的分配系数,并利用商值法对目标PPCPs的生态风险进行评价.结果表明,洪泽湖和高邮湖表层水中∑PPCPs浓度分别是1.56~2534.44 ng·L-1和3.32~1027.47 ng·L-1,沉积物中∑PPCPs含量分别是1.7~926.7 ng·g-1和1.02~289.37 ng·g-1,其中表层水中林可霉素(LIN)浓度最高,沉积物中强力霉素(DOX)含量最高,都以抗生素类药物为主要组分;PPCPs空间分布呈现洪泽湖高、高邮湖低的特征;分配特征表明研究区域典型PPCPs更倾向停留在水相,lgKoc和lgKd之间具有显著相关性,表明沉积物中总有机碳(TOC)对典型PPCPs在水/沉积物系统的分配起重要作用;生态风险评价结果显示PPCPs对表层水和沉积物中藻类的生态风险显著高于蚤类和鱼类,表层水中PPCPs的生态风险高于沉积物,洪泽湖的生态风险高于高邮湖.
英文摘要
      In order to understand the occurrence characteristics and ecological risks of pharmaceuticals and personal care products (PPCPs) in surface water and sediments of Hongze Lake and Gaoyou Lake in the lower reaches of the Huaihe River, 43 surface water and sediment samples from 23 sampling sites were collected, and 61 PPCPs were detected in the samples. The concentration level and spatial distribution of target PPCPs in Hongze Lake and Gaoyou Lake were analyzed, the distribution coefficient of typical PPCPs in the water/sediment system in the study area was calculated, and the ecological risk of target PPCPs was evaluated using the entropy method. The results showed that the PPCPs in surface water of Hongze Lake and Gaoyou Lake were 1.56-2534.44 ng·L-1 and 3.32-1027.47 ng·L-1, respectively, and those in sediment were 1.7-926.7 ng·g-1 and 1.02-289.37 ng·g-1, respectively. The concentrations of lincomycin (LIN) in surface water and doxycycline (DOX) in sediment were the highest, and antibiotics were the main components. The spatial distribution of PPCPs was higher in Hongze Lake and lower in Gaoyou Lake. The distribution characteristics of typical PPCPs in the study area showed that typical PPCPs tended to stay in the water phase, and there was a significant correlation between lg Koc and lg Kd, indicating that total organic carbon (TOC) played an important role in the distribution of typical PPCPs in the water/sediment system. The ecological risk assessment results showed that the ecological risk of PPCPs to algae in surface water and sediment was significantly higher than that of fleas and fish, the ecological risk value of PPCPs in surface water was higher than that in sediment, and the ecological risk of Hongze Lake was higher than that of Gaoyou Lake.
