为了解大厂涉重金属采选行业企业尾矿库废水中重金属（镉、铅、砷、汞、锑）在直接受纳自然水体—平村河中时空分布特征，在尾矿库排放口—受纳水体上游—受纳水体下游布设5个监测断面，监测5种重金属（镉、铅、砷、汞、锑）含量，其含量在排放口—受纳水体上游—受纳水体下游呈阶梯式下降；不同水期镉、铅、锑丰水期含量大于枯水期，砷和汞则是丰水期含量小于枯水期；铅、砷、锑在受纳水体中存在超标现象，受纳水体附近居民取水存在风险。
為瞭解大廠涉重金屬採選行業企業尾礦庫廢水中重金屬（鎘、鉛、砷、汞、銻）在直接受納自然水體—平村河中時空分佈特徵，在尾礦庫排放口—受納水體上遊—受納水體下遊佈設5箇鑑測斷麵，鑑測5種重金屬（鎘、鉛、砷、汞、銻）含量，其含量在排放口—受納水體上遊—受納水體下遊呈階梯式下降；不同水期鎘、鉛、銻豐水期含量大于枯水期，砷和汞則是豐水期含量小于枯水期；鉛、砷、銻在受納水體中存在超標現象，受納水體附近居民取水存在風險。

Five monitoring sites were set up along Pingcun river to monitor the heavy metals (cadmium,lead,arse-nic ,mercury,and antimony)discharged from Dachang Tailings wastewater.The content of the five metals declined hierarchically along the river from upstream to downstream.The content of cadmium and lead and antimony in wet season was higher than that in dry season.However,arsenic and lead in dry season were less than those in wet sea-son.The content of lead and arsenic and antimony could not reach the national discharge standard,which led to health risks for local residents to use the water in the river.
