About fine particles (PM10, PM2.5)Fine particles, particulates or particulate matter (PM) are tiny particles of solid or liquid droplets – known as aerosols – found in the air.
The combustion of fossil fuels is the principal source of emissions of fine particles, this includes the burning of coal, oil, diesel fuel and gasoline.
Aerosols even occur naturally, originating from:
Until now most monitoring was focused on PM10. But due to the effects
on health and environment PM2.5 are becoming of increasing interest.
Impact of fine particles on your healthThe microscopic small solids and liquids comprised in particles can be carried into the lungs. Fine and especially ultrafine particles get deep into the lungs where they can cause inflammation and a worsening of the symptoms of people suffering from heart and lung disease; some particles even get into the human bloodstream. In addition, they may carry carcinogenic compounds into the lung and may lead to other health problems such as premature death, the exacerbation of asthma, acute respiratory problems, chronic bronchitis and decreased lung function.
