Web-Desk (April 17, 2018): The 95 per cent of the world’s population breathes dangerous air, says a report published by the Health Effects Institute.
According to the research, China’s air pollution exposures have stabilised and have even begun to decline slightly; however, Pakistan, Bangladesh, and India, in contrast, have experienced the steepest increases in air pollution levels since 2010.
The particulate matter (PM) standard set by the World Health Organization (WHO) has continued to exceed the PM2.5 Air quality guideline established by WHO.
Based on the data and knowledge of the populations in each country for 2016, 95 per cent of the world’s population lives in areas that exceeded the WHO Guideline for PM2.5. 58 per cent of the global population resided in areas with PM2.5.
On top of the list are countries in North Africa, West Africa and the Middle East who have the highest grossing concentration of dangerous air.
The population-weighted annual average PM2.5 concentrations were recorded 101 µg/m3 in Bangladesh, 78 µg/m3 in Nepal, and 76 µg/m3 in both India and Pakistan. The population-weighted annual average concentration in China was 56 µg/ m3.Estimates for population-weighted annual average PM2.5 concentrations were found to be lowest in Australia, Brunei, Canada, Estonia, Finland, Greenland, Iceland, New Zealand, Sweden, and several Pacific island nations.
