Qualities of environmental water are generally evaluated by physico-chemical data such as pH, chemical oxygen demand(COD), biochemical oxygen demand and total organic carbons. Although these values show the quantities of organic and/or inorganic compounds, they do not indicate the real adverse effects on aquatic organisms. In this work, we examined seasonal changes in coastal water quality by using the micronucleus test in marine fish as well as mutagenic assays and COD analysis of water samples. The frequency of micronuclei in peripheral erythrocytes and gills of several kinds of fish increased in summer, especially in hiiragi(Leiognathus nuchalis). However the micronuclei frequency showed no correlation with the mutagenic activity of coastal water or with their COD data. Therefore, the micronucleus test in aquatic organisms may be a useful tool for the evaluation of coastal waters contaminated with genotoxic compounds.
