    In this paper, we studied the mutage-nicity of organic extracts from water and fish in the process of fish-farming with sewage and observed the changes of their mutagenic activities before and after treatment of municipal wastewater by oxidation pond. The samples were collected in various seasons from 1988 to 1990 and were tested by use of Ames test with two strains TA98 and TA100. It was found that the mutagenicity of samples had been reduced after treatment by oxidation pond and the differences were...

    In this paper, we studied the mutage-nicity of organic extracts from water and fish in the process of fish-farming with sewage and observed the changes of their mutagenic activities before and after treatment of municipal wastewater by oxidation pond. The samples were collected in various seasons from 1988 to 1990 and were tested by use of Ames test with two strains TA98 and TA100. It was found that the mutagenicity of samples had been reduced after treatment by oxidation pond and the differences were statistically significant. The results suggest that the treatment by oxidation pond has some purifying effects on the mutagenicity of organic substances from wastewater and fish.

    Mutagenicity of 6 kinds of extract from diesel engine exhaust particulates were detected by using Ames test. The result indicated that 6 kinds of the sample possessed mutagenicity of TA98 strain. The dose-response relationship existed between the does of diesel exhaust particulates and mutagenicity. Ames test showed that all these exhausts were in TA98 strain in absence of mammalian activation system. These results indicated that organic extracts containing compounds are direct acting and frame-shift mutagens....

    The unscheduled DNA synthesis(UDS) and the inhibition of whole mouse DNA synthesis test(DSI). Were used to detect the mutagenicity of water organic extract substances(WOES) from Nan-Si Lake.The main index that differentiates the damage of DNA matter was inhibition of mouse testicular DNA synthesis. The results show that IVOES from Nan-Si Lake can increase the CPM of lymphocyte apparently; it has significant inhibition for DNA synthesis of liver. Kidney and testis; and there is a significant dose-effect...
