The World Health Organization (WHO) termed air pollution as the world's largest single environmental health risk at the World Health Assembly in Geneva last week.
Air pollution annually accounts for eight million deaths worldwide. China and India are the worst affected countries. The death rate due to air pollution has increased fourfold over the last decade.
"The resolution highlights the key role national health authorities need to play in raising awareness about the potential to save lives and reduce health costs, if air pollution is addressed effectively," according to a press statement from the World Health Organization (WHO).
WHO ranked Delhi as the most polluted among 1,600 cities in the world last year. According to a report by WHO, air pollution in Delhi is 10 times higher than acceptable standards.
According to WHO, exposure to air pollution leads to increased risk of cancer, cardiovascular diseases, such as strokes, ischemic heart disease and respiratory diseases.
By next year, WHO is expected to propose a roadmap for an enhanced global response by the health sector that reduces the adverse health effects of air pollution.
