Application of biomarkers in aquatic environmental research

WANG Hai-li; TAO Shu(Department of Urban and Environmental Sciences, Peking University Beijing 100871, China). China Environmental Science. 1999,19(5): 421~426  
As the biological responses that indicate deleterious effects of pollutants in the environment, biomarkers can be classified into two types, indicating the exposure of organisms to the contaminants and the toxic effects of the pollutants.Compared to other monitoring techniques, biomarkers possess the advantages of specificity, early warning and extensive applicability. Currently applied biomarkers in aquatic environments are introduced in this paper. Both biotransformation enzymes and metallothioneins are able to indicate the effects of organic pollutants and heavy metals on aquatic organisms.DNA adducts can serve as indicators for the relationship between organic pollution and genetic mutation. The disadvantages of biomarkers are also discussed and the future prospects are evaluated as well.
