Question

Heavy metals are defined as elements with density

• A. $>5g/c{m}^3$
• B. $<5g/c{m}^3$
• C. $<5g/m{m}^3$
• D. $>5g/m{m}^3$

Answer 1

The correct option is A $>5g/c{m}^3$

Heavy metals
Heavy metals are those chemical elements that are toxic to living beings even at low concentrations and have relatively high density.
Heavy metals have a density greater than $5g/c{m}^3$.
Heavy metals such as arsenic, cadmium, chromium, copper, lead, nickel are found in wastewater from industrial effluents.
