Air Pollution Kills Millions Each Year

Outdoor air pollution is estimated to contribute to more than two-and-a-half million deaths each year, a study has suggested.
It calculated that, each year, 470,000 people died as a result of ozone and 2.1 million deaths were linked to fine particulate matter.
Air pollution increased respiratory and heart disease risks, with the young, elderly and infirm most vulnerable.
The findings appear in the Environmental Research Letters journal.
The team added: “Our methods likely underestimate the true burden of outdoor pollution because we have limited the evaluation to adults aged 30 and older.
The World Health Organization (WHO) says it is difficult to identify the world’s most polluted areas because many cities with high levels of air pollution do not have monitoring systems in place.
“Nevertheless, the available data indicates that air pollution is very high in a number of Asian cities (Karachi, New Delhi, Kathmandu, Beijing), in Latin American cities (Lima, Arequipa) and in Africa (Cairo),” it observes.
But the WHO adds that although most air pollution hotspots are located in developing nations, it says that developed countries are also at risk and the issue is a major environmental risk globally.
Ozone pollution is linked to breathing problems, such as asthma, reduced lung function and lung disease.
