Degradation Technology of Pesticide Residues in Fruits and Vegetables

The term "pesticide residue" refers to pesticides that remain in or on the surface of foods after application of pesticides, including pesticides themselves, metabolites and degradants of pesticides, and toxic impurities. Organophosphorus pesticide-contaminated foods are mainly found in plant foods, especially organophosphorus pesticides with high residual levels of fruits and vegetables. In recent years, poisoning incidents caused by edible vegetables in China have occurred from time to time, and 98% of them are caused by residues of organophosphorus pesticides on vegetables. The problem of pesticide residue pollution has seriously jeopardized human food safety. This issue has become the focus of global attention. For the detection of pesticide residues, pesticide residue detectors can be used. However, what should be done after pesticides are detected? Residue pesticide degradation is a new way to remove pesticide residues.
The degradation of residual pesticides is an important research area for reducing environmental pesticide residues and reducing the negative effects of pesticide poisoning. With the continuous expansion of human demand for agricultural products, the use of pesticides is in a period of rapid growth, and its natural decomposition can not meet human security needs. Therefore, we only use scientific and technological means to promote the degradation of pesticides and improve the safety of agricultural products.
Judging from the current level of science and technology, chemical pesticides are still irreplaceable for a long period of time, so the degradation of pesticide residues is still a research hotspot in various countries around the world. At present, the study on the degradation and removal of pesticide residues must focus on soil and water. There are relatively few research reports on the degradation of pesticide residues on agricultural products, and the methods are relatively simple. Modern researchers are actively exploring the use of physics, biology, and chemistry. Other methods deal with pesticide residues on agricultural products.
The method of chemical treatment of pesticide residue in fruits and vegetables developed in recent years is a good method of pesticide residue treatment. At present, the application of chemical methods for degradation and removal of pesticide residues in fruits and vegetables still requires further systematic and comprehensive research:
(1) Through the systematic and comprehensive study of the effects of different chemical degradation agent concentrations and treatment time on the degradation of organophosphorus pesticide residues on fruits and vegetables, the changes and laws of degradation of organophosphorus pesticide residues by chemical degradation agents under different conditions were revealed. In-depth study on the degradation and removal of organophosphorus pesticide residues on fruits and vegetables by several chemical degradation agents to find the best degradation conditions.
(2) There are few studies on the identification of by-products and toxicological effects of pesticide residues on fruits and vegetables. It is necessary to identify the by-products after degradation of pesticide residues on the basis of a better method of removing organophosphorus pesticide residues, and study the toxicity of pesticide residues to determine the safety of pesticide residue degradation treatment.
(3) There are few studies on the effects of chemical methods on the treatment of pesticide residues in fruits and vegetables, and on the nutrition and quality of fruits and vegetables. The effects of these methods on the nutrition and quality of fruits and vegetables when degrading pesticide residues should be further studied.
Wood research is aimed at the above problems, using chemical methods to discuss the degradation conditions, feasibility, and safety of pesticide residues in fruits and vegetables to provide technical support for future commercial production, not only to meet consumer demand for agricultural product safety, ensure that people Being in good health can also increase the competitiveness of our country's agricultural products in the international market and create conditions for increasing people's income.

Knitted Low Top Sneakers

Knitted Low Top Sneakers
The upper of this knitted low top sneakers does not cover the ankle. Because of this, the skinny part of the foot is exposed, so it looks thinner. The effect of looking to the side is also very long legs, which can bring a good look and feel.
knitted low top sneakers are also very comfortable to wear, suitable for ordinary travel and shopping or daily casual wear. At the same time it is also very good with, whether it is jeans or skirts, it can give people a fresh feeling.
