Abstract
Highway pollution which is one of the urban nonpoint pollution is considered to have a influence on receiving water, because micro toxic substances like polycyclic aromatic hydrocarbons (PAHs) are exhausted from automobiles, etc. As most stormwater from highways washes off such pollutants from road surfaces and is discharged into the receiving water through stormwater drainages, it is important to know pollutant behavior in runoff process and its hazardous impact on ecosystem in the water body. The objective of this study is to survey standing stock and behavior of highway pollutants in their runoff process. It also aims at examining an ecological hazard impact of the highway pollution on the receiving water. As a result, it is shown that toxic level of the highway pollutants is high enough to affect propagation and emergence of Chironomus Yoshimatsui. And it is also shown that the influence of the highway pollutants on emergence does not depend upon only PAHs in the pollutants. In the results, some significant knowledge for the environmental management of urban pollution has been obtained.
