What is Particulate matter (PM₂.₅)?

Particulate matter (PM₂.₅) is tiny bits of stuff floating in the air that we can’t see.

Imagine you're playing with a bag of sand, each grain is like a tiny particle. Now, think about if those grains were so small they could fit inside a dust bunny or even a speck of dirt on your shoe. That's kind of what PM₂.₅ is like: it's tiny particles in the air, so small that 2.5 million of them could line up to make a meter, which is about as long as a big ruler!

When things burn, like wood or cars, they send out these little bits into the sky. You can think of it like when you light a match, there's smoke that comes out, and those are tiny particles going up.

These tiny bits can go all the way into your lungs when you breathe in. They're so small they're like invisible little visitors inside your body! Sometimes they even get stuck deep down in your lungs, it's like when a piece of confetti gets stuck in your shoe and you can't shake it out.

So, PM₂.₅ is like the tiny bits from smoke that float in the air, too small to see but big enough to affect how we feel when we breathe them in.
