Heavy metals have been used by humans for thousands of years, although severe adverse health effects of heavy metals have been known for a long time, exposure to heavy metals continues, Thurr affirmed. The general population is primarily exposed to Mercury via food, fish being a major source of methyl mercury exposure and dental amalgam, she added.
