Lead-based paint has been banned in the U.S. for decades, but some older homes and painted products can still contain it. As the paint deteriorates, the lead can contaminate dust and soil, which increases the risk of unsafe exposure to lead. If youâre concerned about unacceptable levels of lead in your older home, you should call in the professionals in the Bay Area to handle the lead-based paint removal for you.
Unacceptable levels of contamination have been defined according to where the lead is. For instance, 40 micrograms or more of lead in the dust found in a square foot on floors is an unacceptable amount. The same applies to 250 micrograms of lead per square foot of dust on interior window sills, and 400 parts per million (ppm) of lead in the soil found in childrenâs play areas. Soil that is found in places other than childrenâs play areas is considered contaminated at 1,000 ppm.
