As a result lead can now be found in the dust in some homes, in paint, in soil around our homes, in drinking water, and in some dishes and pottery. The greatest exposure to lead in our current environment is the lead-based paint found in older homes. Before the 1970 s, household paint often contained lead, especially the paints used for trim areas such as windows, doors, and railings. As the paint ages, it can chip or crumble into dust. Remodeling projects also increase the amount of exposure as the paint is disturbed.
Lead poisoning occurs when an individual breathes or ingests the lead.
The lead then enters the blood and accumulates in the body over time. Continual exposure causes the levels of lead in the body to increase causing symptoms of lead poisoning to develop gradually. By the time physical symptoms are visible the amount of lead in the body has reached a dangerous level. At Risk Most at risk because of the dangers of lead poisoning to their developing neurological systems are children under the age of six and pregnant women. Construction workers, home renovators, and hobbyists who are exposed to high levels of lead are also in danger.
