San José’s air among cleanest of Latin American cities

If the air seems relatively clear in Costa Rica’s capital, it is. The World Health Organization (WHO) puts San José in fourth place in terms of air quality among Latin American cities.

The Latin American city with the cleanest air is Salvador, Brazil, followed by Cali, Colombia and Guadalajara, Mexico. Still, only Salvador’s air has pollution levels below the WHO’s recommended average of 19 micrograms per cubic meter.

On the other end of the ranking, the most polluted air in Latin America is in Cochabamba, Bolivia, followed by Lima, Peru, Rio de Janeiro, Brazil and Monterrey, Mexico.

The WHO’s Ambient Air Pollution in Cities database ranks cities based on the annual mean concentration of particulate matter — including dust, ash, soot and pollen — in the outdoor air. Nearly 1,600 cities in 91 countries are included in the database.

On a global level, people in Vancouver, Canada breathe the cleanest air of any urban center. Two Australian cities, Melbourne and Sydney, follow Vancouver, while Ottawa, Canada has the fourth best urban air.

Four Indian cities have the worst air quality in the world, according to the WHO database: New Delhi, Patna, Gwalior and Raipur.
