Analysis of Pesticides

Although the use of pesticides in agricultural practices has led to significant increases in crop yields, pesticides remain one of the most dangerous groups of pollutants to human health, fauna and the environment in general. Most pesticides are applied directly to the soil or sprayed on farmland, which can cause environmental pollution. In addition, pesticides can flow into surface water bodies as spray drift or runoff, which can cause water pollution. Widespread contamination of soil and aquatic ecosystems can lead to residues of these pesticides and their metabolites in food commodities and other fields. In this context, pesticide analysis becomes an important field of application.

Mass spectrometry (MS) is an important tool in the analysis of pesticide residues due to its high sensitivity, selectivity, and accuracy. It can detect pesticide residues at very low concentrations, which is important for monitoring food safety and environmental contamination. In addition, MS also helps to identify metabolites of pesticides. By analyzing these metabolites, researchers can gain insight into the behavior of pesticides in the environment, including how they are transported and broken down over time. This information is of great value in understanding the potential impacts of pesticide use on ecosystems and human health.

Current Mass Spectrometry Strategies for Pesticide Analysis

Since the early 1970s, gas chromatography mass spectrometry (GC-MS) has been the primary method for the determination of conventional pesticide residues. However, with the advancement of technology and the development of the times, there is now an obvious trend to increase the application of liquid chromatography (LC) in pesticide residue analysis, including specific / individual and multi-residue methods, especially with the introduction of powerful, easy-to-operate LC-MS instruments to the market, providing new methods for more sensitive and effective analysis of pesticides with greater scope. At present, LC-MS has become a very valuable analytical tool for the determination of modern pesticides and their metabolites, most of which are polar, low volatile and/or thermolabile compounds.
