Pesticide residue analysis is a critical component of food safety, public health, and environmental protection. As the use of chemical pesticides continues to rise in agriculture, the risk of their persistence in food products, soil, and water has become a major global concern. Even trace amounts of residues can accumulate in the human body and lead to long-term toxic effects, making accurate detection and monitoring essential. Modern residue analysis involves a systematic process that includes sample collection, extraction of pesticide molecules, cleanup to remove interfering substances, and quantitative analysis using advanced instruments such as GC-MS/MS, LC-MS/MS, and HPLC. Techniques like QuEChERS (Quick, Easy, Cheap, Effective, Rugged, Safe) have revolutionized sample preparation by enabling efficient multi-residue extraction with minimal solvent use. This abstract highlights the principles, significance, and analytical advancements in pesticide residue detection, emphasising the need for strict regulatory limits, continuous monitoring, and improvement of analytical technologies to ensure the safety of food and the environment
