Heavy metals refer to metals with a density above 4.5 g/cm3, including copper, lead, zinc, tin, nickel, cobalt, antimony, mercury, cadmium, and bismuth. Heavy metals are well-known environmental pollutants due to their toxicity, persistence and bioaccumulation in the environment. Their natural sources include weathering and volcanic eruptions of metal-bearing rocks, while anthropogenic sources include mining and various industrial and agricultural activities. Even a trace amount of heavy metals is detrimental to human health. Once heavy metals enter the human body, they will coordinate with important substances in the human body, changing the normal physiological function of the substance, or even entering the nervous system, interfering with the normal function of the nerve and causing disease (vegetative) and even death.
Heavy metal test kits are important tools for detecting heavy metals (mercury, cadmium, lead, chromium and metalloid arsenic, etc.) in enviroment, as well as an important means to protect human health. According to different test objects, heavy metal test kits are mainly divided into the following categories:
