The book "Pesticide Residues in Agricultural Commodities" addresses the significant issue of pesticide residues in agricultural products. It focuses on the monitoring of pesticide residues in water, soil, as well as in fruits and vegetables, particularly in the cotton-growing regions of Pakistan. The study highlights the health problems caused by these residues and provides a comprehensive literature review, along with detailed methodology and experimental work from a technical perspective. The results underscore the severity of the problem, as pesticide residues can penetrate deeper aquifers, potentially leading to catastrophic consequences for the environment and public health. The book aims to develop strategies for pesticide control and to raise public awareness about the harmful effects of pesticides. It is intended for both students and professionals involved in the use and management of pesticides.
