While paint manufacturers have not been permitted to add lead to their paints since 1980, before then it was a common additive. Adding lead made paints brighter and increased their durability. Experts believe that in some parts of the country, three out of four homes are likely to have some lead paint. Wall paint and pipe solder are probably the most prevalent sources. While experts generally concur that lead is potentially harmful, unfortunately there is little consensus on how much lead is harmful.
Children are particularly vulnerable to the effects of lead contamination.
Scientists believe that lead may cause serious health problems in children, especially young children. It may also cause problems in pregnancy. Experts believe that children under six are at greatest risk from exposure. Children who live or play with other children that have been lead poisoned are at greater risk. As are also children living in pre-1960s homes and children that do not ingest sufficient levels of iron or calcium.
