关于黄浦江水系表层沉积物的现状研究

Status Quo Study on Surface Sediment of Huangpu River Water System

采用1999年东海监测中心在黄浦江及上海市的9条小河浜采集分析的141个表层底泥理化数据,并以上海市的轮渡线划分江段,运用统计软件进行数据处理,结果表明黄浦江水系的铜、锌、镉、铅明显富积,表层底泥的重金属和油类污染较严重,贡献因子主要为重金属、油类,其次为难降解有机氯化合物。小河浜表层底泥的污染比黄浦江干流相对更严重。

41 Surface sediment samples collected from Huangpu River and other creeks in Shanghai suburb have been analyzed to detect and evaluate contamination in 1999. Statistical software was used for data processing. As a result, some heavy metals accumulated obviously, and the major contaminants were heavy metal and oil, and the undegradable chloride also accumulated in sediment in some extent. Almost all creeks sediment contained more pollutants than Huangpa River.
