If you have young kids, it's important to find out whether there's any risk that they might be exposed to lead, especially if you live in an older home. Many toys and other products from outside the United States have also been found to contain lead.
Long-term exposure to lead, a naturally occurring metal used in everything from construction materials to batteries, can cause serious health problems, particularly in young kids. Lead is toxic to everyone, but unborn babies and young children are at greatest risk for health problems from lead poisoning — their smaller, growing bodies make them more susceptible to absorbing and retaining lead.
Each year in the United States, 310,000 1- to 5-year-old kids are found to have unsafe levels of lead in their blood, which can lead to a wide range of symptoms, from headaches and stomach pain to behavioral problems and anemia (not enough healthy red blood cells). Lead also can affect a child's developing brain.
The good news is that you can protect your family from lead poisoning. Talk to your doctor about potential lead sources in your house or anywhere your kids spend long periods of time, especially if they're younger than 3 years old.
And it's important for kids at risk of exposure to undergo blood tests for lead — many people with lead poisoning show only mild symptoms or even no symptoms at all.
Why Is Lead Harmful?
Whether it's inhaled, swallowed, or, more rarely, absorbed through the skin (just by touching a product that contains lead), lead can act as a poison. Exposure to high lead levels in a short period of time is called acute toxicity. Exposure to small amounts of lead over a long period of time is called chronic toxicity.
Lead is particularly dangerous because once it gets into a person's system, it is distributed throughout the body just like helpful minerals such as iron, calcium, and zinc. And lead can cause harm wherever it lands in the body. In the bloodstream, for example, it can damage red blood cells and limit their ability to carry oxygen to the organs and tissues that need it, thus causing anemia.
Most lead ends up in the bone, where it causes even more problems. Lead can interfere with the production of blood cells and the absorption of calcium that bones need to grow healthy and strong. Calcium is essential for strong bones and teeth, muscle contraction, and nerve and blood vessel function.Read Full Article
