Lead. Sources include lead-based paint dust from removing paint by sanding, scraping, and burning.

To protect yourself and your family from lead, find out whether you're at risk. Here are some common questions and answers.

• It was used in house paint until 1978, when it was banned. 
• It was also widely used in gasoline, but has since been removed. 
• Near major traffic corridors, soils may be contaminated from the long-term use of leaded gas. 
• Water is a potential source of lead. This is usually from lead in solder, fixtures and piping in the home. 
• There is no lead in a "lead" pencil! 

Q: How do I know if my children have been exposed to lead?
A: If you live in an older home, your children may be at high risk. All children up to age six should be tested for lead in their blood. Ask your public health department about lead testing programs for children. 

Q: How do I know if my home has significant concentrations of lead?
A: An estimated 57 million U.S. homes have at least some lead paint. Older homes are at greater risk. Prior to 1950, paint contained as much as 50 percent lead. Paint in good condition poses little risk. Paint that is peeling or on deteriorating surfaces is especially risky. Dust created from remodeling an older home can also be a source of lead. 

Do-it-yourself test kits are available at home centers, paint stores and ceramic supply stores. Their sensitivity is limited, though. Also, it may be difficult to get accurate readings on surfaces with multiple levels of paint. For more accurate information, have a professional detection service conduct a lead-based paint risk assessment. 

Q: Should I be concerned if my home has lead?
A: Yes, especially if you have young children in your home. But, it's important to distinguish between the presence of lead paint and a lead paint hazard. Lead paint in good condition may not pose a hazard until sometime in the future--say, if you plan to scrape the paint or remodel. Then paint dust will pose a hazard. 

Q: If lead is detected in my home, what should I do?
A:

• The simplest way to control exposure to lead is through frequent damp mopping to control dust. (Vacuuming can disperse dust particles back into the room.) 
• Pick up loose paint chips with duct tape. 
• Frequent washing of your child's hands and toys will also reduce exposure. 
• It's important not to sand or scrape leaded paint, or do any other activities that generate dust.

Q: Where can I get more information about lead?
A: Contact the National Lead Information Center (1-800-424-LEAD) for answers to specific questions, or its hotline (1-800-532-3394) for print materials, including an Environmental Protection Agency booklet titled Protect Your Family from Lead in Your Home.
