Development of electrochemical sensors for detection of organophosphate pesticides in fruits and vegetables: A review

Abstract

Abstract The use of pesticides for agricultural cultivation may prevent losses due to pest attacks, but excessive and uncontrolled use of pesticides may cause contamination of pesticide residues in the fruits and vegetables. Organophosphate pesticides are highly toxic and their residue in fruits and vegetables may cause neurological disorders in humans. Organophosphate residues may enter the body of animals and humans through oral routes or respiratory systems. Common analytical methods to detect organophosphate require complex sample preparation and sophisticated equipment. Electrochemical detection methods are an alternative in developing organophosphate detection methods in fruits and vegetables. This review provides an overview of the development and performance of electrochemical sensor technology to detect organophosphate residues in fruits and vegetables.
