Pesticide residues and other aspects
The pesticide residue in the soil enters the plant through the root of the plant. The amount of pesticide residues in different plant machines depends on their absorptive capacity to pesticides. The absorptive capacity of different plants to aldrin is peanut > soybean >; oat > barley > corn. After the pesticide is absorbed, the order of distribution in the plant is: root > stem > leaf > fruit.
Pesticides enter rivers, lakes, and oceans, and cause the accumulation of pesticides in aquatic organisms. In the natural fish body, the insecticide containing organic chlorine is quite common, and the concentration factor is 5~40000 times.
