Where there is paint in older homes, there could very likely be lead-based paint. Anyone living or working in a building built before 1978 should assume lead-based paint (LBP) might be present, and protect yourself and your family accordingly.
Lead poisoning can cause serious illness, including brain damage, and is not just a concern for children and pregnant women. Lead poisoning most often occurs via ingesting or breathing in lead dust. Everyone working around old paint should be concerned. Test yourself and your children for lead, even if you believe you are healthy, since a baseline is valuable, whether you are launching any home projects or not. The only way to find out if paint, dust or soil is hazardous is to test them.
Leads toxicity became widely recognized in the late 19th century, although a number of well-educated ancient Greek and Roman writers were aware of the effects and the symptoms of lead poisoning. Lead is a neurotoxin that accumulates in soft tissues and bones. It damages the nervous system and interferes with the function of biological enzymes. Lead poisoning causes neurological disorders ranging from behavioral problems to brain damage. It also affects general health, and the cardiovascular and renal systems.
Lead interferes with some of the body’s most basic biological functions. The human body does not distinguish between lead and calcium. This causes lead to be absorbed into our bones which then leaches calcium from the body. In the U.S., approximately 900,000 children ages 1-5 have a blood lead level exceeding the level of concern.
Lead poisoning is measured through blood testing. The amount of lead in blood is referred to as the “blood lead level”, which is measured in micrograms (one millionth of a gram) of lead per deciliter of blood (μg/dL). The CDC currently uses a blood lead reference value (BLRV) of 3.5 micrograms per deciliter to identify children with blood lead levels that are higher than most children’s levels.
The Safe Drinking Water Act of 1986 and 1988 restricted the use of lead in plumbing fixtures, but lead can still be found in older plumbing.
We take lead hazards and handling of LBP very seriously around here, and have very strict guidelines for handling projects involving LBP. For more on our Lead Safe Practices please read our blog: Lead Paint & Hazardous Materials – How We Keep Everyone Safe
