Question

Diseases caused by heavy metal contamination? I need more information..​

Answer 1

Answer:

A heavy metal is one whose density is more than 5g cm–3. Some heavy metals are lead,

cadmium, mercury, arsenic selenium, as also iron, copper, manganese, selenium, zinc, etc.

All these metals have atomic number greater than 20. Low concentrations of metal like

iron, copper, zinc and some others are essential for organisms. They are called ‘trace

metals’. On the other hand metals like lead, mercury, cadmium and some others are toxic

to organisms above a certain concentration. pzz makes me Brainlyiest
