Lead poisoning, the No. 1 environmental illness of children, is caused primarily by lead-based paint in older homes. Illinois has higher rates of lead poisoning among its children than any other state in the nation. In 2008, more than 5,000 Illinois children were identified with elevated blood lead levels. The most common exposure to lead by children is through the ingestion of paint chips and contaminated dust from deteriorated or disturbed lead-based paint in homes built before 1978.

About 75 percent of Illinois homes built before 1978 contain some lead-based paint. Lead-based paint was used both inside and outside of homes, especially on windows, baseboards, trim and doors to ensure its durability. After many years of exposure to moisture and climate changes, the paint begins to deteriorate, causing lead dust and chips to settle in window wells, and on door frames and porches. Even the deepest layers of lead-based paint can be disturbed during remodeling or home repair. The only way to know for sure if your home contains lead-based paint is to have it tested by a licensed lead professional.
