Can you tell more about particulate matter ? You mean small particles in the air right, so air pollution right ? | ||

Right but specifically solid particles in the air, not just gasses (CO2, NOX, etc.). For example smoke and soot from combustion or dust particles from tires and brakes. | ||

Particulate matter is relatively large particles, so far as air pollution goes. Think things like soot or smoke, rather than specific chemicals. Burning wood and coal produces far more particulates than, say, natural gas or gasoline-gas. | ||

Yes, it's associated with cancer, heart disease, and dementia. | ||
