Urban air in Finland among world’s cleanest
The World Health Organisation has found the Finnish town of Muonio to have some of the cleanest air of the world’s urban centres.
The WHO Global Urban Ambient Air Pollution Database has been updated after studying the city and academic records of nearly 3 000 cities in 103 countries.
Located next to the Swedish border in Lapland, Muonio recorded just two micrograms per cubic metre of ultra-fine particles of less than 2.5 microns and four micrograms per cubic metre of less than 10 microns. This result placed it second from the top worldwide.
Nonetheless, the situation around the globe remains more dire. Urban air pollution levels worldwide increased by eight per cent between 2008–2013. More than 80 per cent of people living in urban areas that monitor air pollution are exposed to air quality levels that exceed WHO limits.
According to WHO, the most polluted city in the world is Onitsha, Nigeria.
