摘要
对长江口区域饮用水源水中64种半挥发性有机污染物(SVOCs)的含量进行了采样分析,平水期7个水厂水源地共检出16种SVOCs,主要包括多环芳烃类、酯类、取代苯类、其他类,其中属于美国EPA优先控制污染物的有13种,属于我国68种优先控制污染名单的有7种,检出污染物的含量均达到标准限值。长江口区域饮用水源水中SVOCs的空间分布表明,南通地区水源主要受到沿江排污口排放的城市工业废水和生活污水的污染,检出的SVOCs种类相对较多,含量均较高,代表性污染物为取代苯类、酯类和多环芳烃类。狼山水厂相对较好。3座水厂丰、平、枯3个水期半挥发性有机物的监测结果表明,枯水期半挥发性有机物浓度最高,平水期其次,丰水期最低。
The contents of 64 kinds of semi-volatile organic compounds（SVOCs） in drinking water sources area of Yangtze Estuary are sampled and analyzed.In normal river flow period,16 kinds of SVOCs are checked out in drinking water sources area for 7 water works,including PAHs,esters,substituted benzenes and others.There are 7 kinds of national priority-controlled organic substances,13 kinds of EPA priority-controlled organic substances.Concentrations of all checked-out compounds can reach the limited value defined by GB3838-2002 in China and EPA.Spatial distribution characteristics of SVOCs in the monitoring area show that the drinking water sources in Nantong area are mainly polluted by industrial discharge and domestic wastewater,and the checked-out SVOCs are divers with higher concentrations;the pollutants of substituted benzenes,PAHs,esters are representative ones.The analysis results show that,the pollution is the most serious in dry season,lighter in normal river flow period and the lightest in wet period.
