In terms of environmental pollution, heavy metals mainly refer to mercury (mercury), cadmium, lead, chromium and metal-like arsenic and other heavy elements with significant biological toxicity.
Heavy metals are very difficult to be biodegraded, but on the contrary, they can be enriched thousands of times in the food chain under the effect of biomagnification, and finally enter the human body.
