    no its more harmfull to young children because younger people aare absorbing nutrience so it there mother has a high amount of lead poisoning then the baby will be very likley to receve lead poising as well

    i think that some old schools at the present have been suffering from issues of water poisoning, because the water pipes were soldered with lead based solder, and so the students would suffer from severe stomach aches.

    befor the 1970's paints contained lead so if you live in an older house which has not been painted recently or even if it was painted the older paints may contain lead in it

    Very nice pictures! Question: how long would it take to KNOW when you have lead poisoning? Question: How long after you have recently come incontacted with lead would you feel the effects of lead poisoning? - Taylor Bridgman.
