Pesticides are widely used in agricultural products to protect crops from insect infestation during cultivation and product transport. With the heightened concern for food safety, “Positive List System was introduced in Japan on May 29, 2006. These limits ban the sale of food containing pesticides that exceed specified concentrations to ensure the safety of food circulating in the market. Currently, residue standards and analytical methods have been established for about 800 kinds of pesticides and veterinary pharmaceuticals, and this number is expected to increase even further. Therefore, there is increasing need for simpler analytical methods capable of simultaneous multi-residue analysis.
Here, using the LCMS-8030, we optimized methods for the simultaneous multi-residue analysis of 43 pesticides, and report the results of the analysis of actual vegetable extracts (paprika and leek) in solution.
