It should be noted that it is a highly polluting and toxic material and by case its intoxication with it can cause enormous problems to the ecosystem and the health of the person who is intoxicated. Lead poisoning is called lead poisoning.

Among the symptoms and disorders that lead causes once in the body, the development of anemia, since its presence in the blood, immediately, will block the synthesis of hemoglobin and the correct transport of oxygen both to the blood and to the rest of the organs.

Because of his great elasticity molecular, initially, the Russian-born chemist Dmitri Ivanovich Mendeleev he did not include it in the periodic table that he created. Now, its elasticity will be closely linked to the temperature environmental, responsible for extending or distending its atoms.

Its most popular applications include: manufacture of accumulators, coatings, pipes, paints, gasoline antiknock, among others.

On the other hand, the word is also used to designate any part made from this material.
