摘　　要：以多溴联苯醚(PBDEs)作为研究对象,对珠江口水环境中多溴联苯醚进行了生态风险问题形成、生态风险分析及生态风险表征。研究结果表明,珠江口水环境中多溴联苯醚的生态风险主要来自五溴联苯醚,其在水相和沉积物相中的计算结果分别为0.000057和0.0073,目前珠江口水环境中多溴联苯醚的生态风险水平较低,暂无生态风险。The ecological risk in the water environment of Pearl River Estuary is investigated in order to assess the toxicity posed to the aqueous biota by PBDEs,and researches on ecological risk problem formulation,risk analysis and risk characterization are carried out.The results of ecological risk analysis show that the risk comes mainly from the pressure of PeBDE with the level of 0.000057 and 0.0073 in the water and sediment,respectively,with lower ecological risk in Pearl River estuary from PBDEs for a while.
