Toxic elements like lead and mercury are known as which pollutant group?

Explanation:
Heavy metals are toxic elements with high density that persist in the environment and can accumulate in living organisms. Lead and mercury fit this group because they share these metal-specific traits, making them particularly concerning pollutants in water resources due to their toxicity and tendency to bioaccumulate over time. The broader term toxic chemicals is too general and doesn’t emphasize the metal characteristics; sediments are simply a material, not a pollutant group; and nitrates and phosphates are nutrients that cause eutrophication, not metals.
