Chemical Residues in Food Grains: The Burning Health Issues in Asian Countries

Abstract

AK Mohiuddin

Food security is a high-priority issue for sustainable global development both quantitatively and qualitatively. Once pesticides are applied, residues may be found in soil, on plant, on harvested product, on application equipment, in water and irrigation canals, in pesticide storage area, on cloth of applicant. Short term poisoning effects like nausea, vomiting, headache, chest pain, eye, skin and throat irritation etc. and potential long-term health effect like allergies, cancer, nervous system damage, birth defects, reproductive problem have been reported in recent decades, adverse effects of unexpected contaminants on crop quality have threatened both food security and human health. Heavy metals, metalloids (e.g., Hg, As, Pb, Cd, and Cr) from pesticides and fertilizers can jeopardize human metabolomics, contributing to morbidity and even mortality. Those during crop production include soil nutrient depletion, water depletion, soil and water contamination, and pest resistance/outbreaks and the emergence of new pests and diseases.
