Pesticide residue detection

Pesticide residues refer to the trace amounts of pesticides that remain in organisms, agricultural products (or food), and the environment after use. In addition to the pesticides themselves, they also include pesticide conversions, metabolites, reaction products, and impurities. They are the general term for pesticides and other related substances. The amount of residual pesticide residues is called residual amount, expressed in milligrams of pesticide residues per kilogram of sample (mg/kg). The residual agricultural/veterinary drugs in agricultural products pose a serious threat to human health&Nbsp; Baijian Group's laboratory has always operated according to cutting-edge international laboratory standards, equipped with the most advanced agricultural residue detection equipment and a professional testing technology team. It can provide over 600 individual agricultural residue testing services, covering dozens of different products such as vegetables, fruits, tea, grains, traditional Chinese medicine materials, honey, extracts, etc. Shitong Testing has customized over 40 pesticide residue testing packages for customers according to different export country standards, product matrices, and enterprise requirements, providing customers with fast, accurate, and fair practical solutions to help food companies meet product safety and quality standards and avoid pesticide residue risks&Nbsp;
