When it comes to endangering the quality and safety of agricultural products, most people think of pesticide residues, but in fact, with the continuous deterioration of farmland pollution in recent years, heavy metal pollution has become an important factor in the quality and safety of agricultural products. In the process of growing crops, in addition to the application of pesticides will directly lead to pesticide residues, and endanger the quality and safety of agricultural products, if the heavy metal substances in the soil exceed the standard, it will also be absorbed by the crops, causing heavy metals in agricultural products to exceed the standard, and endanger the quality and safety of agricultural products. Therefore, in addition to further reduction and control of pesticides, it is also important to use portable heavy metal detectors to carry out surveys of soil heavy metals to guide the adjustment of agricultural planting structure in the safeguarding of agricultural product quality safety.
Heavy metals mainly refer to metals whose specific gravity is greater than 4 or 5, such as iron, manganese, copper, zinc, cobalt, nickel, titanium, molybdenum, mercury, lead, cadmium, and arsenic. Although heavy metals such as iron, manganese, copper, and zinc are trace elements required for life activities, mercury, lead, cadmium, arsenic, etc. are not essential for life activities, and when all heavy metal contents exceed a certain concentration, they are toxic to the human body. Therefore, to protect the quality and safety of agricultural products, it is necessary to prevent excessive heavy metals from entering the human body through agricultural products. Detecting heavy metal content in agricultural products is a method of bringing about a temporary solution. To completely eliminate heavy metal hazards, we must start from the source and soil, strictly Control the heavy metal content in the soil and finally cut off the hazardous channels of heavy metals. Portable heavy metal detectors play the most important role in soil heavy metal detection and soil science improvement.
In addition to absorbing the effects from the soil, crops will also absorb heavy metals. Therefore, if the content of heavy metals in the soil is controlled within a safe range, the quality and safety of agricultural products can be truly guaranteed, and the long-term use of land can be achieved. The portable heavy metal detector can quickly and accurately detect the contents of five kinds of pollutants such as lead, mercury, cadmium, chromium, and arsenic, help the agricultural sector to accurately grasp the distribution of heavy metal pollution in agricultural production areas, guide the adjustment of agricultural planting structure, and provide scientific protection for the quality and safety of agricultural products. in accordance with.
