Finland is known for its pure nature, air and water, as well as its safety. In 2019, Finland was ranked the world’s safest country to visit by the World Economic Forum.

#Cleanest air in the world

The cleanest air in the world is in the Finnish Lapland. It is proven that the world’s cleanest respiratory air is in the Muonio municipality of Western Lapland. In Muonio, there are only 4 microgrammes of particles of under 10 micrometres in a cubic metre, while in the world’s dirtiest city, Nigeria’s Onitsha, there are almost 600 microgrammes.

 

The database for 2016 of the World Health Organisation (WHO) reveals that the clean localities in the world are usually small, affluent and located far from industrial areas. Other particularly clean localities are Norman Wells, Canada, Campisábalos, Spain, and Converse County, United States. The WHO list took into account the mass concentrations of fine particles whose diameter is less than 10 micrometres (PM10). The diameter corresponds to a seventh part of a hair’s thickness. Particles of under ten micrometres travel with respiratory air into the human bronchi.
