You have recently discovered that your child has an elevated blood lead level. Suddenly, you begin frantically cleaning and inspecting everything in your home. There must be lead hiding somewhere in your older Victorian-style house, right? You check every surface your little one touches for peeling paint, metal objects, or anything suspicious that resembles the images you found during your late-night Google searches about childhood lead poisoning.

How much lead does it actually take to elevate a young child’s blood lead level? Those DIY lead test kits from the home improvement store did not show anything. So where is the lead coming from? How is your child being exposed? What else can you do?

The truth is, you often cannot even see the lead your child is being exposed to unless you happen to find the exact source. It could be an old hand-me-down toy, peeling paint around a favorite windowsill, contaminated dust, or soil tracked into the home on the shoes you remind everyone to take off before they come inside. It only takes a tiny amount of lead to create a big problem.

So how tiny are we talking?

Let’s put it into perspective. Imagine your child’s favorite juice box that is half full. Now picture a single grain of salt. Tiny, right? Next, imagine dividing that grain of salt into 20 even smaller pieces. Then sprinkle just 5 of those tiny pieces into the juice box. Can you see them? No — they are practically invisible to the naked eye. Yet that tiny amount is enough to elevate a young child’s blood lead level.

There are many other factors that can affect a child’s blood lead level as well. Their diet, hand-to-mouth habits, environment, growth rate, and even bowel habits can all play a role. However, it all starts with those microscopic lead particles. These particles can come from old paint, household dust, soil, dirt, or items that contain lead.

It may sound overwhelming, but childhood lead poisoning can be prevented. With education, proper cleaning, healthy nutrition, available resources, and support from healthcare and public health professionals, families can take important steps to protect their children.

For more information, please contact your child’s pediatrician, the Caroline County Health Department, or the Maryland Department of the Environment.
