| Abstract |
Water samples from 3 rivers, the Yodo River in Osaka, the Sumida River in Tokyo and the Tsurumi River in Yokohama, were examined for the mutagenicity by observing micronuclei (MN) in root cells of Allium cepa. Water samples from the Yodo River were collected from two sites, Nagara Bridge and Hirakata Bridge. The treatments of cells with the water samples from Nagara Bridge for 48 h gave rise to significant increases in number of cells with MN in 3 out of 9 experiments. However, the water samples from Hirakata Bridge did not induce MN. The water samples from the Sumida River (Komagata Bridge) showed positive results in 2 out of 9 experiments. The treatments of cells with the water samples from the Tsurumi River (Otsuna Bridge) did not cause significant increases in number of cells with MN. These results seemed to show that waters from the Yodo and the Sumida River were sometimes polluted with mutagenic materials.
