Air pollution ranks behind high blood pressure, diet and smoking as the fourth greatest risk factor for fatalities worldwide, according to the Global Burden of Disease study, done by the Institute for Health Metrics. It kills more than 5.5 million people around the world each year, with over half of those deaths occurring in fast-growing China and India, revealed researchers.
And the number of premature deaths will continue to climb in the years ahead unless more aggressive measures against pollution are adopted, scientists warned the American Association for the Advancement of Science conference in the US capital.
Air Pollution
Nearly 2.4 million deaths every year are attributable to air pollution. Air pollutants may be solid particles, liquid droplets or gases. Proper planning methods should be adopted to reduce air pollution.

"Air pollution is the fourth highest risk factor for death globally and by far the leading environmental risk factor for disease. Reducing air pollution is an incredibly efficient way to improve the health of a population," said Michael Brauer, a professor at the University of British Columbia's School of Population and Public Health in Vancouver, Canada.
China and India account for 55% of yearly global deaths from air pollution. Some 1.6 million people died of air pollution in China in 2013, while India saw 1.4 million deaths.

Air pollution levels on Saturday showed recordings of less than 100 micrograms/m3 at nine locations, which is more than 50 percent less than average recordings.
In China, burning coal is the biggest contributor to poor air quality - and pollution from coal was found to have caused 366,000 deaths in 2013, said Qiao Ma, a PhD student at the School of Environment at Tsinghua University in Beijing, China. Ma projected that air pollution will cause anywhere from 990,000 to 1.3 million premature deaths in 2030 unless more ambitious targets are introduced.
Ma said, "Our study highlights the urgent need for even more aggressive strategies to reduce emissions from coal and from other sectors."
"In India, the main culprit was burning wood, dung and biomass for cooking and heating. India needs a three-pronged mitigation approach to address industrial coal burning, open burning for agriculture, and household air pollution sources," said Chandra Venkataraman, professor of Chemical Engineering at the Indian Institute of Technology Bombay, in Mumbai, India.
The World Health Organization (WHO) air quality guidelines suggest that pollution should be restricted to a daily particulate matter of 25 micrograms per cubic meter.
"In February, Beijing and New Delhi typically see daily levels at or above 300 micrograms per cubic meter - or 1,200% higher than WHO guidelines," researchers said.
More than 85% of the global population lives in areas where the World Health Organization Air Quality Guideline is exceeded.
