APPLICATION OF GAS CHROMATOGRAPHY-MASS SPECTROMETRY FOR THE NON-TARGETED ANALYSIS OF PESTICIDES RESIDUES IN SOIL AND RICE EXTRACTED BY QUECHERS METHOD DURING POST-MONSOON SEASON IN INDIA.

Pesticide residues are the traces of pesticides that remain on or in food and feed after they have been applied to crops. India is one of the countries that falls in the category of top 10 consumers of pesticides worldwide. India is a major agricultural force in the world. Along with having the greatest herd of buffaloes, wheat, rice, and cotton in the world, it is the world's largest producer of milk, pulses, and spices. To increase the yield for the fulfilment of the daily requirement of the population, usage of pesticides on crops to prevent pest damage is increasing drastically. The majority of study focuses on specific pesticide residue screening, missing the opportunity to examine any additional undesired pesticide residues in environmental samples. In 18 villages in the Amroha district of Uttar Pradesh, India, we carried out our research. In this work, we conducted a non-targeted investigation of pesticide residues in the soil and rice crop during the post-monsoon season. Thirty-six soil and rice samples from the same field were studied. Analytes from soil and rice samples have been extracted using QuEChERs. Agilent Technologies' 7000D Triple Quadrupole Mass Spectrometer has been utilized for non-targeted analysis of pesticide residues with the aid of a broad Agilent MassHunter library search. Five different types of pesticide residues have been found, along with their respective amounts. All of the chemicals' mean concentrations were higher than allowed, which is concerning for the ecosystem. 2-Imidazolidinone was the main deadly pesticide residue found in rice and soil, with mean concentrations of 8.86 and 6.78 mg/g, respectively. Trimethyl dihydroquinoline, p-Cumylphenol, 2,4-Dimethylbenzaldehyde, and 3,4-Dimethylbenzaldehyde were the other main pesticide residues found in soil and rice samples. The majority of pesticides fall under the category of herbicides, and they are also metabolites of some extremely poisonous and deadly pesticides that linger in the environment for an extended period of time. This study sought to determine the quantity and concentration of pesticide residues found in soil and rice samples from the Amroha area. [ABSTRACT FROM AUTHOR]
