What are pollution particles?

Pollution particles are tiny bits of stuff that float around in the air and can get into your lungs.

Imagine you're playing with a big bag of lego blocks, some are small, some are big. Now imagine someone threw all those lego pieces into the air, and you had to breathe them in. That’s kind of what happens with pollution particles. They’re like tiny legos or dust that float around in the sky.

Sometimes they come from cars, when a car goes vroom, it leaves behind little bits of soot, which is like dark, smelly dust. Other times, they come from factories, imagine a giant blender full of smoke and dirt mixing together and flying up into the air.

They’re super small, some are as tiny as a grain of sand, others are even smaller than a speck of dust on your nose! You can’t see them most of the time, but they're there, floating in the air you breathe.
