Anthropogenic contaminants are ubiquitous in the environment. These environmental pollutants enter the environment via various entry path for example wastewater treatment plants or pesticide application in agriculture. Released into the environment some are detected in surface waters. The environmental fate of contaminants depends on their physicochemical properties and on the local conditions. Contaminants may be transformed by biotic or abiotic processes like photo-transformation or hydrolysis. Aquatic organisms are exposed to contaminants which are present in...
