    Lead Poisoning A Historical Perspective About Epa Us Epa

    Sep 16, 2016 Lead mining and smelting began in the New World almost as soon as the first colonists were settled. By 1621 the metal was being mined and forged in Virginia. The low melting temperature of lead made it highly malleable, even at the most primitive forges. Furthermore, leads resistance to corrosion greatly enhanced its strength and durability.
