Organophosphorus pesticides residues in food and their colorimetric detection

Pesticides are enormously used to control the pests in agriculture, industry and human premises. Agricultural production has been significantly increased with the help of pesticides but their uncontrolled and excessive use is polluting the environment, food, water and agricultural products. Presence of pesticides residues in food products and human milk is the alarming sign to set up stringent monitoring system and eradication remedies. Many advancements have been happened in recent years for the detection and quantification different pesticides in the various matrices. The present review article specifically focuses on the detection techniques for the organophosphorus pesticides. Organophosphorus pesticides are now a days hugely applied in agriculture after ban on many organochlorine pesticides and hence creating health complications. Visual or colorimetric detection of the pesticides using different nanostructures is considerably exploited for the onsite monitoring of organophosphorus pesticides. These advancements in pesticides detection are presented in detail along with brief overview of pesticides removal methodologies.
