Oct 24, 2024 · Outdoor air pollution is a major environmental health problem affecting everyone in low-, middle-, and high-income countries. Ambient (outdoor) air pollution in both cities and rural areas was estimated to cause 4.2 million premature deaths worldwide per year in 2019; this mortality is due to exposure to fine particulate matter, which causes cardiovascular and respiratory disease, and cancers.
WHO monitors the exposure of air pollution and its health impacts (deaths, DALYs) at the national, regional and global level from ambient (outdoor) and household air pollution. Such estimates are used for official reporting like the world health statistics, and the Sustainable Development Goals. The Air Pollution Data Portal includes Burden of Disease statistics, air quality databases and ...
Pollutants not only severely impact public health, but also the earth’s climate and ecosystems globally. Most policies to reduce air pollution offer a “win-win” strategy for both health and climate. Lower levels of air pollution result in better cardiovascular and respiratory health of populations in both the long- and short-term. Reducing ambient and household air pollution can also ...
May 19, 2020 · The unit for Air Quality and Health, Air Pollution and Health, provides support in the development of guidance, tools and provision of expertise and advice on health issues related to air pollution.
