Kolkata Pollution Fueled by Road Dust, Not Just Vehicles: Study

Imagine the air in Kolkata is like a big soup of tiny particles that make it hard to breathe.

People used to think cars and factories were making the soup the dirtiest.

But a new study found something surprising!

The biggest problem is actually dust from the roads.

This road dust makes up a lot of the yucky stuff in the air.

Cars and factories also add some, but not as much as the dust.

In the winter, people burning things in their homes also makes the air worse.

Sometimes, pollution from other places, like Bangladesh, blows into Kolkata too.

So, to make the air cleaner, city leaders need to focus on cleaning up the roads and stopping dust, not just looking at cars and factories.
