Pesticides & Metabolites Analytical Standards
Pesticides refer to chemicals that can be used in agriculture to prevent plant diseases and insect pests and regulate plant growth. As a chemical agent, its chemical structure will undergo certain changes when it acts, such as decomposition or bonding to generate pesticide metabolites. Residual metabolites after the pesticides have taken effect may contaminate the soil and water, and may increase the resistance of germs and pests to pesticides, and even cause damage to plants. Therefore, in the application of pesticides, not only pests and weeds should be prevented and eliminated, but also the side effects of pesticide metabolites should be considered.
In the process of research and development of pesticides, both the metabolic process and the metabolic results need to be studied. Therefore, pesticide and metabolite analytical standards are produced according to the needs of research and development and other processes. These standards all need to meet the purity of the analysis and have certain standards.
Application fields
Environmental test: The main ways that pesticides pollute the environment are the random dumping of surplus or invalid pesticides, and the loss of pesticide metabolites in the soil and water. When assessing environmental standards, some soil or water samples are often taken in the laboratory, and the samples are analyzed using analytical methods such as chromatography, infrared spectroscopy, and absorbance spectroscopy. Due to the unknown nature of the sample, it is necessary to use pesticide and metabolite analysis standards as standards for qualitative analysis to determine the types of pollutants, and then to perform quantitative analysis to determine the degree of pollution, thereby obtaining an environmental standard report.
Surface residue measurement of fruits and vegetables: In agriculture, in order to increase the yield and quality of fruits and vegetables, pesticides are used in cultivation. As people pay more attention to health, the standards for pesticide residues in fruits and vegetables are becoming stricter, and highly toxic pesticides are prohibited. In standardized production, there are regulations on the types and amounts of pesticides used by plants, and such regulations are based on the quality of the products obtained. Residues on the surface of fruits and vegetables are one of the criteria for measuring product quality. This requires qualitative and quantitative analysis of residues based on pesticide metabolism standards.
Research and development of pesticides: In addition to the effects of pesticides, agricultural research and development needs to consider the toxicity and pollution of pesticide residues. Therefore, the laboratory needs to use pesticide metabolism standards to study the mechanism of pesticide action, so as to obtain pesticide formulations that meet the standards.
