Before we start each section, we’ll ask you a question to help you see how much you you've learned.

Different forms of pollution in the environment can have negative effects on children's health. For example, the increase of diseases like cancer, diabetes and asthma, as well as conditions that affect the way the brain develops, from the womb, has occurred at the same time as air pollution, electronic waste and the use of harmful chemicals in everyday products has increased in many countries of the world.

One of the most dangerous and least visible forms of pollution is lead poisoning, which disproportionately affects children.

Think of lead pollution as a kind of ghost that haunts your children’s good health throughout their lives.

Lead is a quiet intruder. You can’t taste it, you can’t smell it, and you can’t see it with your own eyes. It slips into our lives unnoticed—like a ghost hiding in plain sight.

But this ghost doesn’t have to haunt our homes. Lead poisoning can be prevented when we learn where it hides and take action to push it away and protect our families.

There is no cure for lead pollution; the damage it causes is permanent. Prevention is the only cure.

Being exposed to lead is very dangerous. It can affect children’s brains for life and can cause serious health damage.

By reading this information, you are already doing something very important to protect your children.
