India's heat and dust image persists: the country was ranked
the ninth most polluted country in the world by the Global Health Report 2014
on air pollution levels, by the World Health Organization.The annual report was
prepared after studying outdoor air quality and pollution levels in 1,600
cities of 91 countries across the world. The effect is severe - the study
blames seven million deaths in 2012 on exposure to air pollution, both indoor
and outdoor. About 3.7 million deaths were due to exposure to outdoor pollution
alone, the report says.
