Chile warns over air pollution risk09/06/2012 - 10:06:20
Chile has issued an environmental alert for its capital Santiago because of air pollution.
Santiago is bordered by the snow-capped Andes mountains and smog from cars and factories is often bottled up. City officials have placed limits on industries and on the circulation of cars.
It is the first environmental alert for Santiago this year. Pollution is common during the Southern Hemisphere’s autumn and winter months, and recent dry conditions have made conditions worse.
