1. What is lead?

Lead is a highly toxic metal that was used for many years in products found in and around our homes.

2. What are the health effects of lead?

Because the early symptoms of lead poisoning are easy to confuse with other illnesses, it is difficult to diagnose lead poisoning without medical testing. Early symptoms may include persistent tiredness, irritability, loss of appetite, stomach discomfort, reduced attention span, insomnia, and constipation. Failure to treat children in the early stages can cause long-term or permanent health damage. The current blood lead level which defines lead poisoning is 10 micrograms of lead per deciliter of blood.

3. Where is lead located?

lead paintOlder homes may contain lead based paint.

Lead was used as a pigment and drying agent in "alkyd" oil based paint. "Latex" water based paints generally have not contained lead. About two-thirds of the homes built before 1940 and one-half of the homes built from 1940 to 1960 contain heavily-leaded paint. Some homes built after 1960 also contain heavily-leaded paint. It may be on any interior or exterior surface, particularly on woodwork, doors, and windows. In 1978, the U.S. Consumer Product Safety Commission lowered the legal maximum lead content in most kinds of paint to 0.06% (a trace amount). Consider having the paint in homes constructed before the 1980s tested for lead before renovating or if the paint or underlying surface is deteriorating.

5. How do I submit a sample to test for lead content?

Paint chips can be collected and submitted to a laboratory for lead analysis. The US National Institute of Occupational Safety and Health (NIOSH) has developed a number of methods for analyzing lead in paint, including Methods 7082, 7105 and 7300. The paint sample collected should be about about 2.5 centimeter (cm) by 2.5 cm in surface area. When collecting paint samples, you must make sure that all of the layers of paint or coating are collected, right down to the original surface. If you cannot remove the paint from the substrate, you can submit the sample with it attached.
