(Heavy metal) detection

BAIJIAN - a professional third-party testing and inspection platform that provides testing (heavy metal) testing and other related testing and inspect

Heavy metals refer to metals with a specific gravity greater than 5, including gold, silver, copper, iron, lead, etc. Heavy metals accumulate to a certain extent in the human body and can cause chronic poisoning. Heavy metals cannot be biodegradable, but on the contrary, they can accumulate thousands of times under the biological amplification of the food chain before entering the human body. Heavy metals can interact strongly with proteins and enzymes in the human body, causing them to lose their activity. They can also accumulate in certain organs of the human body, causing chronic poisoning
