A report published by the Health Effects Institute, says that 95 per cent of the world’s population breathes dangerous air.
According to the study, China’s air pollution exposures have stabilized and have even begun to get worst however, Pakistan, Bangladesh, and India, in contrast, have experienced the steepest increases in air pollution levels since 2010.
The tiny particles of dust matter (PM) standard set by the World Health Organization (WHO) has continued to go beyond the PM2.5 Air quality guideline established by WHO.
Based on the data and knowledge population in each country for 2016, 95 per cent of the world’s population lives in areas that went beyond the WHO Guideline for PM2.5. 58 percent of the worldwide population lived 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 next-highest concentrations appeared in South Asia where burning things from multiple sources, including household solid fuel use, coal-fired power plants, agricultural and another open burning, and industrial and transportation-related sources, are the main contributors, the report states.
The population-weighted Annual average PM2.5 concentrations were recorded 101 Âµg/m3 in Bangladesh, 78 Âµg/m3 in Nepal, and 76 Âµg/m3 in both India and Pakistan. The population-weighted annual average concentration in China was 56 Âµg/ 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 other Pacific island nations.
Vice president of the institute, Bob O’Keefe, said the gap between the most polluted air on the planet and the least polluted was striking. While developed countries have made moves to clean up, many developing countries have fallen further behind while looking for economic growth.
