Special Pollutants: Lead

Lead is toxic to humans. Children under the age of six years are especially sensitive to lead poisoning. Lead poisoning can slow a child's development and cause learning and behavioral problems. Adults may also be affected by high lead levels, which can cause headaches, high blood pressure, digestive problems, memory and concentration problems, mood changes, sleep disorders, and muscle and joint pain. It can also cause abnormal development of an unborn baby when a pregnant woman is exposed.

The lead hazard occurs primarily from exposure to dust from lead-based paint. When lead-based paint deteriorates, paint dust containing lead is released. This paint dust can be inhaled and eaten by the people living and working in buildings painted with lead-based paints.

The Minnesota Department of Health is a good resource for information on lead poisoning prevention.

Tips for Reducing the Risk of Lead Exposure in the Home

• Test your child for lead. A simple blood test can detect high levels of lead.
• Have your home checked for lead hazards. Peeling paint around windows and sills, doors and other areas can create lead dust, which is breathable and may come in contact with children's hands. Lead paint was commonly used until the 1970s.
• Clean up paint chips immediately.
• Clean floors, window frames and sills, and other surfaces weekly, using warm water and an all-purpose cleaner. There are some cleaners made specifically for lead.
• Thoroughly rinse sponges and mops after cleaning dirty and dusty areas.
• Wash children's hands often, especially before meals, nap and bed times.
• Regularly clean play areas, and wash bottles, pacifiers, toys and stuffed animals.
• Keep children from chewing window sills or other painted surfaces.
• Take precautions to avoid exposure to lead dust when remodeling or renovating (call 1-800-424-LEAD for guidelines).
• Don't use a belt-sander, propane torch, dry scraper, or dry sandpaper on painted surfaces that may contain lead.
