苏州河底泥营养物质空间分布及环境风险评价OACSTPCD
Spatial Distribution and Assessment of Environmental Risks of Nutrients in Sediment of Suzhou River
为研究苏州河底泥中营养物质空间分布及环境风险,在上海河段进行样品采集,采用有机指数法和营养物质比值对营养物质进行环境风险评价.结果表明:有机质(OM)、总氮(TN)、和总磷(TP)均未超过背景值.沿程OM、TN先波动性下降后上升,TP呈波动性下降趋势;垂向上因截流前的累积效应、截流后底泥与上覆水的交互作用,OM、TN和TP总体趋势为先波动后略微上升又下降.利用有机指数评价可知,在0～22km为清洁,22 km后属于轻度污染;垂向上环境风险为清洁.…查看全部>>
In order to study the spatial distribution and environmental risks of nutrients in the sediment of Suzhou River,samples were collected in the Shanghai reach,and the organic index method and nutrient ratio were used to evaluate the environmental risks of nutrients.The results showed that organic matters(OMs),total nitrogen(TN),and total phosphorus(TP)did not exceed the background value.OMs and TN decreased first and then increased along the route,while …查看全部>>
