| Research Abstract |
The objective of this study is to survey standing stock and behavior of urban nonpoint pollutants in their runoff process. It also aims at examining an ecological impact of the urban pollution on the receiving water. From the surveys on the standing stock and behavior, differences in content ratio of pollutants in urban sediments from their sources to receiving water were shown. And, from the examination on the ecological impacts, ecological toxicity of the urban sediments for Chironomus yoshimatsui was shown. As a result, some significant knowledge for the environmental management of urban pollution has been obtained.
