Heavy Metals Hesperian Health Guides

Jun 16, 2020· Heavy metals such as arsenic, mercury, cadmium, uranium, and lead are harmful to people even in very small amounts. Because many metals are found together at mine sites, it is often hard to know which metal may be causing health problems. Lakes and rivers in California, USA, are still poisoned by mercury from gold mining over 100 years ago.
