Particulates

Particulates are very tiny things that float in the air or water. They are so small that you can't see them without using a special machine called a microscope.

Particulates can come from lots of different things, like smoke, dirt, dust, or even tiny pieces of metal. When we breathe in air that has particulates in it, they can get into our nose and lungs. This can make it hard to breathe or even make us sick.

People try to reduce the amount of particulates in the air and water because too many can be bad for our health and the environment. They do this by using filters or scrubbers that take out the particulates, or by using different types of materials that don't make as many particulates. It's important to keep our air and water clean so we can stay healthy!
