Present day lead pollution is an environmental hazard of global proportions. A correct determination of natural lead levels is very important in order to evaluate anthropogenic lead contributions. In this paper, the impact of mining and smelting of lead metal ores on environmental quality is described.

Smelting involves heating the ore with a reducing agent such as charcoal, coke or other purifying agents. Although it is beneficial to the metal production industry, it also has many hazards that if left uncontrolled can impact the environment. Smelting is perceived to be a primary cause of water pollution in its vicinity.

Key Points. • After iron, aluminium is the second most-used metal in the world. • After oxygen and silicon, aluminium is the third most abundant element in the earth's crust. • In Europe, after transport (39%), construction at 24% is the second largest application. 1. • In 2012, on average, each European citizen used 22kg of aluminium 1.
