Emissions of fine particles
Fine particles in ambient air cause respiratory and cardiovascular diseases and reduce the average life expectancy. Fine particles are a mixture of very small solid particles and liquid droplets, made up of a number of components and having a diameter under 10 micrometres (PM10). Ultrafine particles are the fraction of fine particles and have a diameter under 2.5 micrometres (PM2.5.).
