Abstract
Pesticides, as the name suggests, are those substances that inhibit, destroy or resist a harmful organism (pest), from any disease and protect the plant and crops during the production. The use of pesticides are increasing worldwide due to large population and their needs. Small quantity of the pesticides is used to kill or control the pest whereas, left pesticides remain in environment or absorbed by the food material, water is harming the health of humans, and aquatic life. Thus, the screening of these pesticides is important to ensure legally acceptable quantity ‘MRLs’ of pesticides that should be used in controlling the pests or disease. Different advanced techniques such as Gas Chromatography-Mass Spectrometry (GC-MS), High Performance Liquid Chromatography (HPLC), Liquid Chromatography-Mass Spectrometry (LC-MS), Enzyme Linked Immunosorbent Assay (ELISA) and so on have been developed to detect the pesticides. These techniques have high sensitivity, high accuracy, reliability and less time consumption capability but some techniques have drawbacks i.e., HPLC has a low sensitivity for pesticides in food. This review paper studies different analytical techniques for the detection of pesticides in food. Keywords: Pesticides, MRLs, Chromatography
Introduction
Chemical substances are those substances which are used in agricultural field to increase the production with high quality by controlling the pests is known as pesticides. These pesticides include insecticides, herbicides, fungicides, disinfectants and various other substances. The mechanism of pesticide is that it attacks on the targeting system or enzymes in the pests. This mechanism is also followed in the case of humans because of the indistinguishable or much related system or similar enzymes present in human beings. The presence of pollution in air, soil and water is increasing by the greater use of pesticides. The health of humans are at very high risk, not only by misuse or accidental ingestion but also by the traces of chemicals left into the environment that is affecting the health. Pesticides not particularly target pests, it also affect the non-target plants and animals. According to the researchers, only 0.1% pesticides reach to the targets while left pesticides contaminate the surrounding environment (Elhag et al., 2017).
Generally, all creatures, human and environment are facing the problems related to the pesticides but the high risk of exposures is seen in cases of agriculture worker and family members of pesticides applicators. There are different reason of pesticides exposure with the humans which are as follows:
• Spillage from the packaging
• Applying too much pesticides product
• Accidentally, exposure the chemicals during aerial treatment or from spray drift.
• Incorrect use of equipments.
• Failure to follow the label instructions
• Storage of pesticide in unsecured places (Darcin and Darcin, 2016)
