Description

Technical Field

[0001] The utility model relates to the field of heavy metal detection, in particular to soil heavy metal detection equipment. Background Art

[0002] Heavy metals are more prominent among inorganic pollutants in soil, mainly because heavy metals cannot be decomposed by soil microorganisms, but are easily accumulated and converted into more toxic methyl compounds. Some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health. The main heavy metal pollutants in soil are mercury, cadmium, lead, copper, chromium, arsenic, nickel, iron, manganese, zinc, etc. Although arsenic is not a heavy metal, its behavior, source and hazards are similar to those of heavy metals, so it is usually included in the heavy metal category for discussion.

[0003] Existing equipment for detecting heavy metals in soil can only perform single sampling tests on a certain surface of the land or on relatively shallow ground. It fails to sample soil at different depths on the same vertical plane. Since the heavy metal content of soil at different depths may be different, the test results are likely to be inaccurate.
