The extensive use of pesticides, their disposal and consequent presence in various environments are of great concern regarding their ecotoxicological effect on the organisms of different trophic levels. Such widespread use results in an increased concentration of these compounds in water, sediments and soils. Chemical pesticides undergo many different pathways once they enter the environment, including transformation/degradation, sorption-desorption, volatilization, uptake by plants, runoff into surface waters and transport into groundwater. Transformation or degradation is one of the key processes that governs the environmental fate and transport of chemical pesticides, which also comprises different processes including abiotic degradation and biodegradation. During these processes, chemical pesticides are transformed into the degradation products or are completely mineralized to a carbon field. Although abiotic degradation plays a role in many cases, the biodegradation of chemical pesticides by microorganisms is usually the most important and dominant process.
