  • What is metal pollution?

    heavy-metal pollution Environmental pollution by metals with a high relative atomic mass, such as lead and mercury.
    These metals derive from a number of sources, including lead in petrol, industrial effluents, and leaching of metal ions from the soil into lakes and rivers by acid rain.

  • WHO standards for heavy metals in sediments?

    The EPA heavy metal guideline for sediment indicated not polluted (Table 4).
    The WHO maximum permissible level in soil is 2000 mg/kg (Table 3).

  • What is the introduction of heavy metal pollution?

    Heavy metals emitted into the atmosphere during mining, smelting, and other industrial activities are deposited on land by dry and wet deposition.
    Discharge of wastewaters such as industrial effluents and domestic sewage add heavy metals to the environment.

  • What is the introduction of heavy metal pollution?

    Most heavy metals cause environmental and atmospheric pollution, and may be lethal to humans.
    Heavy metals can become strongly toxic by mixing with different environmental elements, such as water, soil, and air, and humans and other living organisms can be exposed to them through the food chain.
