Fish as Indicators for Environmental Monitoring and Health Risk Assessment Regarding Aquatic Contamination with Pesticides

The proximity of water basins to anthropogenic sources of pollution affecting the state of nature also determines the need to study the ecosystems existing there. Fish are used as reliable indicators of pollution of the aquatic environment. Changes in the fish body make it possible to determine the toxicity of the contaminated water and the potential danger posed by anthropogenic substances that have entered it. In this regards, biomarkers are important assessment tools as they provide specific information on the biological effects of a particular toxicant. They can be used for monitoring purposes, as well as to clarify the link between the effects on the organism and the concentration of the contaminant in health risk assessment.
