Lead: The most extensively spread toxic environmental contaminant
1. Introduction Lead (Pb) is in the fourth group of the periodic table with an atomic number of 82. Since naturally occurring Pb is a mixture of isotopes with mass numbers 204, 206, 207, and 208, with 207 being the most common, the atomic weight of lead is 207.21 g/mol. Pure Pb is gray in color and has a specific gravity of 11.34.
