Jul 29, 2024 · Air pollution is contamination of the indoor or outdoor environment by any chemical, physical or biological agent that modifies the natural characteristics of the atmosphere. Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include ...
Nov 1, 2018 · How air pollution affects our body. Particles with a diameter of 10 microns or less (≤ PM 10) can penetrate and lodge deep inside the lungs, causing irritation, inflammation and damaging the lining of the respiratory tract. Smaller, more health-damaging particles with a diameter of 2.5 microns or less (≤ PM 2.5 – 60 of them make up the ...
Sep 1, 2022 · In addition to health, air pollution is also linked to biodiversity and ecosystem loss, and has adverse impacts on human capital. Reducing air pollution, on the other hand, not only improves health but strengthens economies. A recent World Bank study found that a 20% decrease in PM 2.5 concentration is associated with a 16% increase in ...
Sep 22, 2021 · Русский. Español. New WHO Global Air Quality Guidelines (AQGs) provide clear evidence of the damage air pollution inflicts on human health, at even lower concentrations than previously understood. The guidelines recommend new air quality levels to protect the health of populations, by reducing levels of key air pollutants, some of which ...
Nov 7, 2024 · Healthier environments could prevent almost one quarter of the global burden of disease. The COVID-19 pandemic is a further reminder of the delicate relationship between people and our planet. Clean air, stable climate, adequate water, sanitation and hygiene, safe use of chemicals, protection from radiation, healthy and safe workplaces, sound agricultural practices, health-supportive cities and built environments, and a preserved nature are all prerequisites for good health.
Jul 12, 2023 · Air pollution is a major environmental threat and one of the main cases of death among all risk factors, ranking just below hypertension, tobacco smoking and high glucose. WHO estimates that, globally, air pollution is responsible for about 7 million premature deaths per year from ischemic heart disease, stroke, chronic obstructive pulmonary disease and lung cancer, but also from acute respiratory infections such as pneumonia which mainly affects children in low- and middle-income countries.
Mar 28, 2024 · The Bangladesh Country Environmental Analysis (CEA) finds air pollution, unsafe water, poor sanitation and hygiene, and lead exposure cause over 272,000 premature deaths and 5.2 billion days of illness annually. These environmental issues cost the equivalent of 17.6 percent of Bangladesh's GDP in 2019. Household and outdoor air pollution have ...
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.
24%. of all estimated global deaths are linked to the environment. Household air pollution. 3.2 million. deaths every year as a result of exposure to indoor smoke from cooking fuels. Ambient air pollution. 4.2 million. deaths every year as a result of exposure to fine particulate matter.
