What is Mold?
- Mold is a type of fungus. These small organisms can be black, white, orange, green, or purple and live almost anywhere indoors and outside. Molds thrive on moisture and reproduce through lightweight spores that travel through the air. You’re exposed to mold every day. They’re usually harmless in small amounts. But when they land on a damp spot in your home, they can start to grow. They release spores that you might breathe in. If you're sensitive to mold and inhale a lot of spores, it could make you sick.

What is Asbestos?
- Asbestos is found in rocks and soil. These mineral fibers have worked well for manufacturers for many reasons. For starters, they’re flexible and resistant to heat, chemicals, and electricity. That’s why they were widely used for years to make construction materials, automotive parts, and even textiles.
-The fibers that form asbestos separate very easily into tiny pieces when they’re handled or damaged. They’re too small to see, but they’re easy to breathe in. They can build up in your lungs and cause health problems.

What is Lead?
Lead is a metal that’s found in nature, deep within the ground. It exists all around us too -- in the air, soil, water, and even in our homes.
In the late 1970s, the federal government passed measures to reduce the amount of lead in the environment and in the products we use. Still, it’s often found in things like paint, ceramics, pipes, plumbing materials, and cosmetics.
