Lead and Your Health

Lead dust is a common means of exposure in the U.S. Many older homes, built before 1978, probably contain . lead-based paint, inside and out. When that paint cracks or peels, it makes lead dust. The soil around homes can contain lead from old exterior paint. Children can breathe in lead dust or eat lead from soil,

How Does Lead Affect Our Environment? - The Green Optimistic

The Impact Lead Has on Plants . Plants have evolved to cope with the naturally low level of lead in the soil. However, they are not going to thrive in an area where mining tailings and buried lead-acid batteries pollute the soil with lead. Lead in the soil inhibits seed germination and seedling development.
