望虞河沿线特征污染物本底调查分析
Baseline survey and analysis of characteristic pollutants along the Wangyu River
摘要
Abstract
The Wangyu River is a key conduit of the Yangtze-to-Taihu water diversion project,and its water quality is directly related to the water supply security of the Taihu Lake basin.In this study,a comprehensive baseline survey was conducted simultaneously along the main stem and tributaries of the Wangyu River and the Gonghu water source,targeting four categories of characteristic pollutants—heavy metals,algal toxins,plasticizers,and emerging contaminants—to investigate their spatial distribution and variation patterns.The results reveal a general decreasing trend in pollutant concentrations from the Wangyu Sluice toward the Gonghu Lake.The sluice,serving as the entry point of the diverted flow,is identified as the primary source of heavy metals and plasticizers,while the tributaries along the Wangyu River corridor emerge as potential risk zones for algae and emerging contaminants.Based on the spatial distribution characteristics of the pollutants,differentiated control measures were proposed for three types of risk zones:the area near the sluice,the tributary regions,and the Gonghu water source area.For the vicinity of the sluice,point-source interception of industrial antimony and plasticizers along with routine online monitoring is recommended.For the tributary areas,enhanced management of nitrogen and phosphorus non-point sources coupled with algal early warning systems and emergency odor-removal treatment processes should be implemented.For the Gonghu water source area,a long-term monitoring mechanism for microcystins and perfluorooctanoic acid(PFOA)should be established.Although constrained by the limited spatiotemporal representativeness of a single sampling campaign and the absence of monitoring of sediment analysis and PFOA homologues,this baseline survey provides fundamental data for coordinated water quantity-quality regulation of the Yangtze-to-Taihu water diversion project.It also points toward future research directions,including long-term monitoring,sediment-water interface flux studies,and systematic assessment of emerging contaminants.关键词
