| Research Abstract |
We sampled river waters, industrial and municipal wastewaters, and roadway runoffs from Yoshino River watershed area and conducted ecotoxicological tests using short-term chronic tests using three organisms, fish, daphnia, and algae, under discussion by Japan Ministry of Environment. Relatively strong toxicity was found for daphnia and fish larva for most of the industrial and municipal wastewater samples and some of their receiving waters. The strong toxicity was detected only for riverwaters sampled in urban streams. As for roadway runoffs, strong toxicity for daphnia and algae was found and the contribution of PAHs and some heavy metals were suspected.
