To comprehend the situations of sediment contaminations in Tokyo bay canal zoon, sediment survey were conducted at multiple point. Compare the sediment in canal zoon with bay sediment, sediment in canal zoon indicated higher values of ignition loss, Cu, Zn, Sb and Pb. This result suggested that sediment in canal zoon is more deteriorating. Regarding Cu and Zn, their speciations were different between sediment in canal zoon and bay sediment. Since speciation patterns in canal zoon were similar to those in combined sewer sediment, it was suggested that there are some contaminants from combined sewer overflow in canal zoon.

为了解东京湾运河区沉积物污染状况，对多点沉积物进行了调查。将运河区沉积物与海湾沉积物进行比较，运河区沉积物的烧失量、Cu、Zn、Sb、Pb值较高。这一结果表明运河区沉积物的恶化程度更为严重。对于Cu和Zn，运河区沉积物和海湾沉积物中Cu和Zn的形态存在差异。由于运河区中的物种形成模式与合流制下水道沉积物中的形态模式相似，因此表明运河区中存在一些来自合流制下水道溢流的污染物。
