Hazard of pesticide residues Pesticide residue refers to the phenomenon where pesticides, directly or indirectly, remain in grains, vegetables, fruits, livestock products, aquatic products, and soils and bodies of water after pesticides are applied in agricultural production.

Some of the currently used pesticides can be biodegraded into harmless ones in a relatively short period of time, while organochlorine pesticides including DDT are difficult to degrade, and are highly residual pesticides (see Organic Chlorine Pesticides). According to the residual characteristics, residual pesticides can be divided into three types: pesticides that are easily left in the plant body are called plant residual pesticides, such as 666, Endrin, etc.; pesticides that are easily left in the soil are called Soil residual pesticides, such as aldrin, dieldrin, etc.; soluble in water, and long-term residual pesticides in the water known as residual pesticides in water, such as endrin. There are two types of residual pesticides in plants, soils, and bodies of water: one is to maintain the original chemical structure; the other remains in the form of chemical conversion products or biodegradation products.
Pesticides that remain in the soil enter the plant through the plant's root system. The amount of pesticide residues in different plant organisms depends on their ability to absorb pesticides. The absorption of aldrin from different plants was as follows: peanut> soybean> oat> barley> corn. After pesticides are absorbed, the order of their distribution in plants is: root> stem> leaf> fruit.
The Pesticide Residue Tester can quickly detect pesticide residues in the sample. The sensitivity is high, and the minimum detection limit for pesticides such as methamidophos and dichlorvos is better than the national standard.
