Lead poisoning is and has been a serious problem for children and some adults.
Since ancient times, man has used lead for making pipe, paint pigments, and ceramics. Because of its plasticity and softness, lead can be rolled into sheets and foil. It can be made into rods, pipes and tube containers. Lead is used in building construction for roofing, cornices, tank linings, electrical conduits, water pipes and sewer pipes. It is used for yacht keels, plumb bobs and sinkers in diving suits.
