What are some environmental problems caused by heavy metals?

Contamination of aquatic and terrestrial ecosystems with toxic heavy metals is an environmental problem of public health concern. Being persistent pollutants, heavy metals accumulate in the environment and consequently contaminate the food chains.

Where does heavy metal toxicity come from?

Heavy metal poisoning is caused by the accumulation of certain metals in the body due to exposure through food, water, industrial chemicals, or other sources. While your body needs small amounts of some heavy metals to function normally — such as zinc, copper, chromium, iron, and manganese — toxic amounts are harmful.
