Element 82 in our International Year of the Periodic Table series is lead. Lead and its compounds have previously been used in petrol, water pipes and paints, though its toxicity has led many of its uses being discontinued. It’s still used in car batteries and bullets.
Lead’s use also continues in bullets, organ pipes, weight belts for diving, and cable sheathing.
