AOAC Method 2007.01 Gas Chromatography for Pesticide Residue

Detection target

Detection of pesticide residues

Introduction

Pesticide residue testing involves the qualitative and quantitative analysis of pesticides and their metabolites that may remain in agricultural products, food, and the environment. Its purpose is to ensure food safety, protect public health, and promote sustainable agricultural development. With the widespread use of chemical pesticides in agricultural production, the problem of pesticide residues in crops, soil, and water sources is becoming increasingly prominent. These residues can enter the human body through the food chain, potentially leading to acute poisoning, chronic diseases, and even cancer risks. Pesticide residue testing techniques primarily utilize gas chromatography and must cover various types of pesticides, including organophosphates, organochlorines, and pyrethroids. Through systematic monitoring and risk assessment, pesticide residue testing provides crucial scientific evidence for agricultural product quality and safety regulation, international trade compliance, and environmental protection.

Overview

This solution conforms to the AOAC Official Method 2007.01 Pesticide Residues in Foods by Acetonitrile Extraction and Partitioning with Magnesium Sulfate Gas Chromatography / Mass Spectrometry and Liquid Chromatography / Tandem Mass Spectrometry. AOAC Official Method 2007.01 is a standard method for the determination of multiple pesticide residues in food, based on the QuEChERS method. It utilizes 1% acetic acid acetonitrile extraction, acetate buffer salting-out, and PSA/MgSO₄ dispersive solid-phase extraction (dSPE) cleanup, combined with GC/MS and LC/MS/MS for qualitative and quantitative analysis. It is suitable for fruits and vegetables with high water content.
