This is an area we feel very strongly about. Aluminum wiring in a house presents a very serious potential fire hazard. We feel that there are a significant number of homeowners who have aluminum wiring and who haven't yet taken steps to make their homes safe.
We have a greater concern with metal jewelry because of the higher level of exposure. It's around the neck, on the wrists -- that's in addition to hand-to-mouth contact, so there's a stronger potential that more lead can get to the body.
