Analysis of Impurities in Lead Sponsored by PerkinElmerFeb 19 2021 Lead (Pb) is extremely toxic to living organisms, prompting this element to be phased out of an array of products. However, Pb is still frequently employed in a number of applications, most notably alloys, lead-acid batteries, radiation shielding, ammunition, flashing in the construction industry and as lining in industrial pipes and baths designed to carry corrosive substances. To accommodate this wide range of uses, an equally wide range of grades and purity levels of lead are produced. The London Metal Exchange is responsible for issuing specifications for an array of different metals in several grades.
