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.

为了理解东京湾运河周围沉积物污染的情况，在多个点进行了沉积物调查。比较运河zoon中的沉积物与凸出沉积物，在运河畜群中的沉积物表明点火损失值更高，Cu，Zn，SB和PB。该结果表明，运河周围的沉积物更恶化。关于Cu和Zn，在运河清季和湾沉积物中的沉积物之间的规格不同。由于运河zoon中的物种模式与下水道混合沉积物中的物种模式相似，因此建议在运河周围的下水道溢出中有一些污染物。
