| 中文摘要 |
| 长江地表水中频繁检出的新型有机污染物对生态健康构成了威胁,且不同区域存在生态风险的差异. 为综合分析长江地表水中新型有机污染物污染特征及影响其生态风险的关键因素,对20 a来已发表文献中长江地区污染物赋存数据进行综述分析. 首先采用生态风险评估策略筛查出需重点关注的污染地区及优先管控新型有机污染物,其次分析了城市社会发展与污染物发生之间的联系. 结果表明,长江干流地表水新型有机污染物种类包括3大类、20小类和412种,检出浓度范围为10-5~103 ng·L-1,其中挥发性有机污染物、邻苯二甲酸酯、杀虫剂、杀菌剂和除草剂的浓度最高. 不同区域地表水污染物浓度及种类存在明显差异,整体表现出东部多西部少的特点,工业类集中在下游（安徽-上海）,农药类集中在中游（武汉-安徽）. 高生态风险新型有机污染物大多为工业产品类以及药品和个人护理产品类. 不同级别城市污染物空间分布特征受人口密度、城市面积、人均GDP、第二产业比例影响大,城市的人类活动程度是污染物分布差异较大的主要原因. |
| 英文摘要 |
| The frequent detection of emerging organic pollutants in the surface water of the Yangtze River poses a threat to ecological health, and differences exist in ecological risks in different regions, which are related to the socio-economic development of cities along the Yangtze River. To comprehensively analyze the pollution characteristics of new pollutants in the surface waters of the Yangtze River and the key factors affecting their ecological risks, this review study analyzed the data on pollutants in the Yangtze River Region from the published literature over the past 20 years. First, we used the ecological risk assessment strategy to screen the polluted areas that require attention and prioritized new pollutants, followed by revealing the links between urban social development and pollutant occurrence. The results showed that the new pollutants in the surface water of the Yangtze River mainstem included three categories, 20 subcategories, and 412 types, and the detected concentrations ranged from 10-5 to 103 ng·L-1, among which the concentrations of volatile organic pollutants （VOPs）, phthalate esters （PAEs）, insecticides, fungicides, and herbicides were high. Significant differences were observed in the concentration and types of surface water pollutants among different regions, namely more in the east and less in the west, with industrial categories concentrated in the downstream （Anhui-Shanghai） and pesticides concentrated in the midstream （Wuhan-Anhui）. Most emerging pollutants with high ecological risk belonged to the industrial product category and the pharmaceutical and personal care product category. The spatial distribution characteristics of pollutants were greatly influenced by population density, urban area, per capita GDP, and the proportion of secondary industry, and the degree of human activities in cities was the main reason for the large differences in the distribution of pollutants. |
