为了解伴砷金属矿开发对附近河流及沉积物影响，采集广西某典型伴砷金属矿区附近河流沉积物，进行砷含量和形态分析及生态风险评价。结果表明，沉积物中砷含量均较高，已经构成污染，河流沉积物中As来自矿区的支流。Hakanson潜在生态风险评价结果表明，河流中游和支流沉积物中As呈现出较强的生态风险，而下游相对较小。

In order to find out the effects of arsenic -rich metal ores development on the nearby rivers and sediments ,the sediments in the nearby river of one typical arsenic -rich metal ores in Guangxi are collected to conduct analyses on concen-tration of As ,speciation and ecological risk assessment .The results show that there is high arsenic content in river sediments along the stream direction and As in river sediments comes from the tributary area .It also shows that As shows strong ecolog-ical risks in midstream and tributary rivers sediments ,while the downstream is relatively small .
