Over recent decades, environmental pollution is rapidly increasing because of the anthropogenic 
activities of uncontrolled development, for example, industry, transport, agriculture, and 
urbanization, which generates harmful contaminants for living organisms including humans. These 
contaminants get accumulated in the organism via different routes and get bioaccumulated in 
different tissues exerting detrimental effects at different levels (molecular, cellular and 
physiological levels). The measurement of biological assays in sentinel species to access quality and 
changes of the environment is known as environmental biomonitoring which provides an indication 
of environmental stress. Several biomarkers evaluate the nature and extent of the exposure and 
evaluation of adverse biological responses to pollutants in a biomonitoring program of the aquatic 
environment. These include behavioral response, genotoxicity (comet assay and micronucleus 
assay) and oxidative stress. Here we present the importance of these biomarkers.
