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.
Sep 22, 2021 · The WHO Air quality guidelines are a set of evidence-based recommendations of limit values for specific air pollutants developed to help countries achieve air quality that protects public health. The first release of the guidelines was in 1987. Since then, several updated versions have appeared and the latest global version was published in 2005.
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 reduce emissions of carbon dioxide (CO2) and short-lived climate pollutants.

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 modelled exposure and estimates of both ambient and household air pollution.
Mar 15, 2022 · Air pollution leads people to be exposed 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. WHO data show that almost all of the global population (99%) breathe air that ...
Sep 22, 2021 · Clean air is fundamental to health. Compared to 15 years ago, when the previous edition of these guidelines was published, there is now a much stronger body of evidence to show how air pollution affects different aspects of health at even lower concentrations than previously understood. But here’s what hasn’t changed: every year, exposure to air pollution is still estimated to cause millions of deaths and the loss of healthy years of life.
Air pollution. Air pollution is a major and pressing public health threat. WHO estimates that around 7 million people die every year from exposure to fine particles in polluted air that lead to diseases such as stroke, heart disease, lung cancer, chronic obstructive pulmonary diseases and respiratory infections, including pneumonia.
Jun 25, 2024 · In 2019, air pollution caused about 6.7 million deaths. Of these, almost 85% are attributable to noncommunicable diseases (NCDs), including ischemic heart disease, stroke, lung cancer, asthma, chronic obstructive pulmonary disease (COPD), and diabetes. This makes air pollution the second leading cause of NCDs globally after tobacco.
