In agricultural production, due to human activities, many heavy metals are introduced into the soil, causing the content of heavy metals in the soil to be significantly higher than the original content, causing a deterioration of the ecological environment, and the heavy metals in the soil are different from other pollutants. Heavy metals have relatively stable physical and chemical properties in soil and poor migration. Heavy metal pollution will not only damage soil structure, affect soil physical and chemical properties and microbial community structure, but also reduce the stability of soil ecological balance. Therefore, it is very necessary and important to use a portable heavy metal detector to prevent and control soil heavy metal pollution under the current harsh soil pollution. Stearic acid is widely used in the manufacture of PVC plastic pipes, plates, profiles, and films. It is a PVC heat Stabilizer with good lubricity and good light and heat stability. In plastic PVC pipes, stearic acid helps prevent "coking" during processing. It is an effective thermal stabilizer added in the processing of PVC films, and can prevent finished films caused by excessive exposure to sulfides.

The heavy metal pollution in soil is very harmful. The annual amount of grain contaminated by heavy metals is 12 million tons. A large number of cultivated land is abandoned due to heavy metal pollution, which greatly affects grain yield and safety. Therefore, the problem of soil heavy metal pollution must be paid attention to. In order to do a good job in the prevention and control of soil heavy metal pollution, the agricultural sector has also actively introduced portable heavy metal detectors to comprehensively assess soil pollution in various regions through testing, and strictly prevent and control human activities according to the pollution conditions and avoid agriculture. Farmland caused further damage.
If agriculture is to continue to develop, it must maintain a good soil environment and ensure the health of the soil where the crops grow. In the face of the severe problem of heavy metal pollution in the soil, the first thing to do is to find out and use convenient portable heavy metal detectors. And effective soil testing equipment to test soil samples, determine the presence and severity of heavy metal pollution, and study the status and mechanism of heavy metal pollution. From the perspective of governance needs, we should reasonably distinguish secondary pollution from human activities and non-modern human-made primary pollution, and then formulate scientific and reasonable pollution prevention and control measures so as to maximize the effectiveness of governance and eventually achieve environmental and social benefits. Economical organic unity.
