There was a time when pencils were filled with lead, we often licked them for the smudge effect when we were drawing chimney smoke. Now of course it is carbon, PC plumbing practices have changed. Can't even sell a house in France if there are lead pipes or asbestos. Lead shot for cartridges has been banned there also, cows had been eating pellets which in turn contaminated the milk, but that's the French, here in Ireland there are still lead pipes delivering domestic water supplies to houses, hospitals and primary schools. As for the buckshot, our town water is tainted with discarded babies nappies, the price of privatisation, cheaper to litter.
