Heavy metal pollution in soil is a common environmental problem in modern agricultural pollution, and it is getting more and more attention from the society. Heavy metal pollution in soil poses a great threat to food security and human health. Therefore, attention to soil quality and safety requires the detection of heavy metals in soil. At present, the main methods for soil heavy metal detection are hyperspectral analysis, atomic fluorescence spectrometry, atomic absorption spectrometry, laser induced breakdown spectroscopy, inductively coupled plasma optical emission spectroscopy, X-ray fluorescence spectroscopy, biomass indirect Determination techniques, etc., but to meet the on-site rapid detection needs of modern agricultural arable soil, we recommend the use of portable heavy metal detectors . The conventional detection method has high technical requirements for the operator, or is complicated in the detection process, and it is difficult to achieve rapid detection on the spot, and there are many drawbacks. With the continuous development of arable land quality protection and upgrading projects in various places, the demand for rapid detection of soil heavy metals is increasing. There is an urgent need for a simpler and more effective technical method to replace conventional testing. The portable heavy metal detector belongs to the soil heavy metal rapid detection instrument, which has the advantages of fast, simple, sensitive and economical. The application of the instrument can not only meet the actual detection needs, but also save a lot of manpower, material resources and time. Heavy metal pollution is one of the most extensive and harmful environmental problems in today's soil pollution. In the face of such a severe situation, effective measures must be taken to contain and repair. The best way is to increase the scope and frequency of soil heavy metal detection. By promoting and applying portable heavy metal detectors such as heavy metal detectors, it provides strong support for the development of related work and is more conducive to the repair of heavy metal pollution in soil.
