CHEMICAL AND PHYSICAL INFORMATION Toxicological

Lead is a naturally occurring element and is a member of Group 14 (IVA) of the periodic table. Natural lead is a mixture of four stable isotopes, 208Pb (5153%), 206Pb (23.5 −27%), 207Pb (20.523%), and 204Pb (1.351.5%). Lead isotopes are the stable decay product of three naturally radioactive elements 206Pb from uranium, 207Pb from actinium, and 208Pb from thorium.
