| 摘 要： | 计算了我国部分河流天然物理化学条件下重金属在水相－颗粒物相间的分配系数，长江水系重金属水－固分配系数大于黄河反映了颗粒物度组成的差异，而长江口重金属－固分配系数大于长江武汉段则反映了离子强度的影响，在此基础上，运用平衡分配法根据实测天然分配系数尝试了长江，黄河沉积物某重金属的质量基准。

| Abstract: | Water-particulate dist ribution coefficient of heavy metal was calculated in natural condition(both physical and chemical)in China rivers. Due to difference of grain size composition, distribution coefficient of heavy metal in the Changjiang(Yangtze River)is greater than it in the Huanghe(Yellow River). For the Changjiang, that distribution coefficient estuary is greater than it in Wuhan station mainly reflects effect of ion intensity. Based on preceding data, sediment quality criteria was proposed in the study. |
