Abstract

In modern civilization, aquatic sources are enormously used as the dumping ground for man made waste which are transformed into most toxic compound in aquatic systems. The aquatic toxicologist, however, revealed the great danger of its effects on xenobiotics in structure and function of aquatic ecosystem. Modem geneticist proposed the link between pollution and genome of aquatic animals. Genetic toxicology, therefore, emerged as a new field of genetics, especially fish genetics. Several cytogenetic assays were developed by modem genetic toxicologist. The genetic toxicology was recognized as a separate branch around 1969 after the Environmental Mutagen Society was established. The environmental mutagens have been classified into three, such as, living, physical and chemical mutagen (Manna, 1982, 1983). The consequence of these pollutions on fin fish and shell fish have been studied by toxicologist. The exploratory . research in this field has identified it as an important environmental problem, all over the world . The effectiveness of these chemicals on hereditary components of living organisms were categorised in genetic toxicology. Brusick (1980) reported that even if many toxic substance damage the genetic material in nonspecific manner, the effect of these agents are highly specific on nucleic acid. Hence these are capable of producing harmful effect at sublethal level.
