-
摘要: 应用高通量分析方法对长江干流重庆段11个断面水体中的潜在污染物进行了分析,共筛查到230种污染物。结合重庆市化学品生产使用统计结果,应用综合评分法对潜在污染物进行了评分和排序,筛选出33种流域重点关注污染物,包括农药、工业用品(邻苯二甲酸酯类、酚类雌激素、有机溶剂)及个人护理品(抗氧化剂、合成麝香、紫外吸收剂)等。结果表明,基于高通量分析方法和综合评分法可成功识别和筛选流域内重点关注污染物,为流域管理提供科学依据。Abstract: A high throughput screening method was applied for screening pollutants in 11 surface water from the Yangtze River in Chongqing City, and a total of 230 pollutants were identified. Composite scoring method, combined with the statistics of their production and use in Chongqing were used to score and rank the priority chemicals. The results showed that 33 compounds were selected as priorities in the Yangtze River of Chongqing section, which included pesticides, industry chemicals and personal care products. This study proved that the developed high throughput analytical method and composite scoring method are able to identify and screen the priority pollutants in the environment at the watershed scale, and provided scientific basis for watershed management.
