New report by WHO flags the huge toll pollution continues to claim despite efforts by governments
Nine out of 10 people around the world breathe air containing high levels of pollutants. An estimated 7 million people every year die of diseases caused by ambient (outdoor) and household air pollution. Of the 15 most polluted cities in the world, 14 are in India, says the report.
These are the findings of a new WHO report which nevertheless praises a government of India scheme for giving LPG connections to rural poor as a step that seeks to nullify the effects of indoor air pollution.
“ For example, in just two years, India’s Pradhan Mantri Ujjwala Yojana Scheme has provided some 37 million women living below the poverty line with free LPG connections…”
“While the latest data show ambient air pollution levels are still dangerously high in most parts of the world, they also show some positive progress. Countries are taking measures to tackle and reduce air pollution from particulate matter. For example, in just two years, India’s Pradhan Mantri Ujjwala Yojana Scheme has provided some 37 million women living below the poverty line with free LPG connections to support them to switch to clean household energy use,” the report said.
WHO estimates that around 7 million people die every year from exposure to fine particles in polluted air that penetrate deep into the lungs and cardiovascular system, causing diseases including stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases and respiratory infections, including pneumonia.
Ambient air pollution alone caused some 4.2 million deaths in 2016, while household air pollution from cooking with polluting fuels and technologies caused an estimated 3.8 million deaths in the same period. More than 90% of air pollution-related deaths occur in low- and middle-income countries, mainly in Asia and Africa, followed by low- and middle-income countries of the Eastern Mediterranean region, Europe and the Americas.
Commenting on the findings of the report, WHO director general Dr Tedros Adhanom Ghebreyesus said: “Air pollution threatens us all, but the poorest and most marginalized people bear the brunt of the burden. It is unacceptable that over 3 billion people – most of them women and children – are still breathing deadly smoke every day from using polluting stoves and fuels in their homes. If we don’t take urgent action on air pollution, we will never come close to achieving sustainable development.”
The highest ambient air pollution levels are in the Eastern Mediterranean Region and in South-East Asia, with annual mean levels often exceeding more than 5 times WHO limits, followed by low and middle-income cities in Africa and the Western Pacific.
“Many of the world’s megacities exceed WHO’s guideline levels for air quality by more than 5 times, representing a major risk to people’s health. We are seeing an acceleration of political interest in this global public health challenge. The increase in cities recording air pollution data reflects a commitment to air quality assessment and monitoring. Most of this increase has occurred in high-income countries, but we hope to see a similar scale-up of monitoring efforts worldwide,” says Dr Maria Neira, Director of the Department of Public Health, Social and Environmental Determinants of Health at WHO.
