Bioaccumulation of Pesticide Residues in Agricultural Food Chains and Their Remediation Using Natural Adsorbent

Pesticide accumulation within food chains has become an essential environmental and health issue for agricultural systems. The research examines pesticide movement in agricultural systems and evaluates natural materials for their remediation potential. In South Gujarat's agricultural sector, organochlorines and organophosphates show significant accumulation patterns across food chain levels. The study investigates pesticide residue binding actions in agricultural biomass throughout this geographic area. Local agricultural waste materials, including sugarcane bagasse, cotton stalks, and rice husk, when modified through phosphoric acid activation, demonstrate high adsorption capacities for common pesticides. The natural adsorbents present affordable and environmentally friendly options compared to industrial standard methods. Natural adsorbents exhibit variable performance levels depending on both environmental conditions and pesticide properties. Surface modification of these locally sourced materials enhances pesticide removal efficiency, offering a sustainable remediation approach for South Gujarat's extensive sugarcane and cotton cultivation zones.
