What is PM10 & PM2.5 and what does it do?
PM10 - Particulate Matter < 10µm (particles likely to be inhaled by humans). Produced by vehicle
exhaust - diesels produce more.

and can effect the heart and blood hence reduce your life expectancy.
PM2.5 - Particulate Matter < 2.5µm - very small, very dangerous and on the increase thanks to Biomass burning.
