Lead: what is it?
Lead is a mined mineral. Like asbestos its use goes back thousands of years throughout human history. The Romans used it in cosmetics, winemaking, and even water pipes. In modern times, lead was added to numerous materials, including gasoline, paint, plumbing pipes, soldered joints, flashing and numerous other construction materials. Also, like asbestos in the 20th century, it was realized that lead had negative health effects when it was inhaled or entered the body via the skin or even eyes or was ingested. Thus, lead was and is still slowly being phased out from everyday products.
Unlike asbestos, lead can affect the whole body, including the reproductive and nervous systems and organs. Lead is especially dangerous to small children as it interferes with the development of the nervous system, causing potentially permanent learning and behaviour disorders. Symptoms of lead poisoning can include abdominal pain, headaches, anemia, irritability, and in severe cases, seizures, coma, and death.
Where can it be found?
In any building older than 40 years, lead products, especially paint, are highly likely to be found. Lead paint on window frames, doors, walls, and other interior or exterior surfaces is often in poor condition, flaking and peeling off. It is essential to contain any lead paint dust resulting from renovations in the home. As with other environmental contaminants, people are often unaware that they’ve been exposed to dangerous materials and that there is a causal connection to their illness.
What can be done about it:
If you suspect you have lead paint in your home, have it tested or leave it alone. If it is in poor condition and must be removed, or you are planning to renovate, consult a lead removal contractor who understands “lead safe” work methods. They will be able to help you decide on a safe way to proceed.
