If soil, especially cultivated soil, suffers heavy metal pollution, it will inevitably bring major hidden dangers to food production security. Therefore, in the current process of protecting and improving the quality of cultivated land, soil heavy metal detection is one of the important testing items. The application of portable heavy metal detectors can not only accurately and scientifically investigate soil heavy metal pollution, but also strengthen soil testing to prevent soil heavy metal pollution scientifically, ensure the quality and safety of arable land, and thereby ensure the safety of food production.
The danger of heavy metal pollution in the soil is not alarmist, but it is real. Taking toxic cadmium rice as an example, the reason why rice becomes toxic food is mainly because the cadmium in the soil exceeds the standard, and rice crops are easier to absorb The cadmium in the soil caused the cadmium in rice to exceed the standard and became toxic rice. Therefore, from the root point of view, to develop safe food production, we must ensure the quality and safety of cultivated land and soil. To carry out a large-scale survey and monitoring of soil heavy metals, technical support is needed, which is portable, portable and portable, and the detection speed of portable heavy metal detectors is more suitable for the efficient and scientific implementation of agricultural soil soil testing in various fields.
There are many sources of heavy metals in soil, which are caused by many reasons. Therefore, to avoid soil heavy metal pollution, one of the effective methods is to strengthen the detection and management of soil by using a portable heavy metal detector. The instrument can detect soil heavy metals with 34 standard elements. Compared with laboratory testing, portable heavy metal detection The instrument is small in size and light in weight, and has the advantages of simple operation, rapid and accurate detection, and portability. The inspectors can be taken directly to the field for on-site detection. Therefore, the application of the instrument can greatly solve the shortage of detection technology at the grassroots level and effectively improve The testing range and testing frequency ensure the quality and safety of the soil.
