Question

chem question

Answer 1

Here's one that hasn't been mentioned: lead pellets from shotguns. After they fall to the ground, the pellets are often eaten by birds, which in turn get eaten by predators, etc. In the U.S, federal regulations require the use of non-lead shot when hunting migratory waterfowl. Stainless steel shot is often used for the purpose. Bismuth shot is used too. It has very good performance, but is expensive. The hunting of non-migratory birds and small game isn't subject to the federal regulations, and lead shot is normally used on them.

Answer 2

Flaking paint from pre-1950 housing is probably the major source. Toddlers may eat the chips. More subtle is the chronic inhalation of lead dust in these older homes. Soil around the foundations of such houses are also highly contaminated. A second source is the leaching of lead from old lead-containing water pipes. Adults can be at risk from inhaling certain industrial fumes, like fumes from welding, pottery glazing, smelting, leaded gasoline or, certain folk-medicine remedies.

Answer 3

Lead based paint and old water pipes are possible indoor pollution sources. Old battery manufacturing sites and illegal dump sites from certain manufacturing facilities can do the job outdoors.

Answer 4

When electricians throw away solder it goes to the landfill and animals that eat at the landfill can get lead poisoning.
