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 deaths per year due to stroke, heart disease, lung 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 and context - specific. Major outdoor pollution sources include residential energy for cooking and vehicles, power generation, agriculture / waste incineration, and industry. Policies and investments supporting integrated policies that support sustainable land use, cleaner household energy and transport, energy - efficient housing, power generation, industry, better municipal waste management can effectively reduce key sources of ambient air pollution. Air quality is linked to earths climate and ecosystems globally. Many drivers of 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 from cooking fires Cause 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 emissions of fine particles other pollutants.

What else causes air pollution?

Pollution is now commonplace term that our ears are attuned to. We hear about various forms of pollution every day and read about through mass media. Air Pollution is one form that refers to contamination of air, irrespective of indoors or outside. Physical, biological or chemical alteration to air in atmosphere can be termed as pollution. It occurs when any harmful gases, dust, smoke enters into atmosphere and makes it difficult for plants, animals, and humans to survive as air becomes dirty. Read here more about facts about air pollution. Another way of looking at air pollution could be any substance that holds potential to hinder atmosphere or well being of living beings surviving in it. Sustainment of all things living is due to combination of gases that collectively form atmosphere; imbalance caused by increase or decrease in percentage of these gases can be harmful to survival. Ozone Layer, Considered Crucial For Existence Of Ecosystems On Planet, Is Depleting Due To Increased Pollution. Global warming, direct result of increased imbalance of gases in atmosphere, has come to be known as biggest threat and challenge that contemporary world has to overcome in bid for survival.

Air Pollution Challenges: Common Pollutants

Great progress has been made in achieving national Air quality Standards, which EPA originally established in 1971 and update periodically based on latest science. One sign of this progress is that visible air pollution is less frequent and widespread than it was in 1970s. However, air pollution can be harmful even when is not visible. Newer scientific studies have shown that some pollutants can harm public health and welfare at very low levels. Epa in recent years revised standards for five of common pollutants subject to national Air quality Standards. Epa make standards more protective because new, peer - review scientific studies show that existing standards are not adequate to protect public health and environment.
