General | Latest Info

From smog hanging over cities to smoke inside home, air pollution poses major threat to health and climate. Ambient air pollution accounts for estimated 4. 2 million per year due to stroke, heart disease, lung cancer, acute and chronic respiratory diseases. Around 91 percentage of world's population lives in places where air quality levels exceed WHO limit. While ambient air pollution affects developed and developing countries alike, low - and middle - income countries experience highest burden, with greatest toll in WHO Western Pacific and South - East Asia regions. Sources of air pollution are multiple context - specific. Major outdoor pollution sources include residential energy for cooking and heating, power generation, agriculture / waste incineration, and industry. Policies and investments supporting integrated that support sustainable land use, cleaner household energy and transport, energy - efficient housing, power generation, industry, and better municipal waste management can effectively reduce key sources of ambient air pollution. Air quality is closely linked to climate and ecosystems globally. Many drivers air pollution are also sources of greenhouse gas emissions. Policies to reduce air pollution, therefore, offer win - win strategy for both climate and health, lowering burden of disease attributable to air pollution, as well as contributing to near - and long - term mitigation of climate change. Exposure to smoke from cooking causes 3. 8 million premature deaths each year, mostly in - and middle - income countries. Burning fuels such as dung, wood and coal in inefficient stoves or open hearths produces variety of health - damaging pollutants, including particulate matter, methane, carbon monoxide, polyaromatic hydrocarbons and volatile organic compounds. Burning kerosene in simple wick lamps also produces significant of fine particles and other pollutants.

What causes bad air quality?

Air pollution can be created by manmade and natural sources. Natural sources include windblown or - up dust, dirt and sand, volcanic smoke, and burning materials. Manmade - sources, meaning that pollution is created by actions of human beings, tend to be leading contributor to air pollution in cities and are inherently more able to be influenced by regulations. Manmade sources primarily include various forms of combustion, such as from Gas - Power transportation and industrial businesses, biomass and agriculture. Contribution of various air pollution sources to locations Air quality is highly dependent on location and regulations. Each location has its own mix of and pollutants. Sources are commonly categorized into following:

Emissions Trends

Air pollution is local, pan - European and hemispheric issue. Air pollutants released in one country may be transported into atmosphere, contributing to or resulting in poor air quality elsewhere. Particulate Matter, Nitrogen Dioxide ground - level Ozone, are now generally recognise as three pollutants that most significantly affect human health. Long - term and peak exposures to these pollutants range in severity of impact, impairing respiratory system to premature death. Around 90 percentage of city dwellers in Europe are to pollutants at concentrations higher than air quality levels deemed harmful to health. For example, F ine Particulate Matter in Air has been estimated to reduce life expectancy in EU by more than eight months. Benzopyrene is carcinogenic pollutant of increasing concern, with concentrations being above threshold set to protect human health in several urban areas, especially in central and eastern Europe. Acidification was substantially reduced between 1990 2010 in Europe's sensitive ecosystem areas that were subject to acid deposition of excess sulphur and Nitrogen Compounds. Eutrophication, environmental problem caused by input of nutrients into ecosystems, saw less progress. Areas of sensitive ecosystems by excessive atmospheric nitrogen diminished only slightly between 1990 and 2010. Crop damage is caused by exposure high Ozone concentrations. Most agricultural crops are exposed to Ozone levels that exceed EU's long - term objective intend to protect vegetation. This notably includes significant proportion of agricultural areas, particularly in southern, central and eastern Europe. Europe's air quality has not always improved in line with general decrease of anthropogenic emissions of air pollutants. Reasons for this are complex: there is not always clear linear relationship between decreasing emissions and concentrations of air pollutants observed in air; there is growing contribution of long - distance transport of air pollutants to Europe from other countries in northern hemisphere. Target efforts to reduce emissions are therefore still required to further protect human health and environment in Europe.
