Air pollution in Krakow poses a significant danger to human health and life. Krakow's poisoned air includes amongst other things: particulate matter, benzo(a)pyrene and nitrogen dioxide.
The city has been rated amongst the most polluted in the world in a World Health Organiation (WHO) study. In the report, Krakow was ranked 8th among 575 cities for levels of PM 2.5 and 145th among 1100 cities for levels of PM 10. Hazardous air quality is a common problem particularly during the colder months when many residents use solid fuels (mostly coal) for household heating. Burning these fuels in heating appliances releases many pollutants into the air. Furthermore, sometimes users of these stoves burn garbage, despite the fact that doing so is forbidden. Each year, pollution levels begin creeping up in autumn, and readings for PM 10 are regularly surging above 100 µg/m3.
Therefore, solid fuel boilers, stoves and furnaces used in households constitute the biggest cause of air pollution with particulate matter (PM10, PM2.5) and polycyclic aromatic hydrocarbons (e.g. benzo[a]pyrene).
