Carbon Dioxide is major pollutant as far as global warming is concerned, but other contributory gases are Methane, Nitrous Oxide, and water vapours. Major urban sources include vehicles, burning of gas, coal and charcoal, wood for cooking and heating, and industrial sources still located in cities. (a) Ozone. It’s also important for governments, to be able to make short and long-term planning decisions to reduce air pollution. Large cities in subtropical and tropical regions that have very light winds and many hours of sunshine, experience serious pollution episodes. It reduces crop yields, forest health and biodiversity generally. Air pollution significantly impacts places near its source, but because it can be carried long distances in the atmosphere, air pollution created in one place, can also affect faraway places. secondary pollutants). Both short and long term exposure to air pollutants have been associated to health impacts. A group of pollutants, called ‘ Short-Lived Climate Pollutants ’ (SLCPs) which include black carbon , ozone, methane , and hydrofluorocarbons (HFCs) , are highly potent climate forcers and – in the case of ozone and black carbon – dangerous air pollutants. Atmospheric conditions, such as wind, affect pollutant dispersion and can vary widely. The report highlights the seven steps that States must implement , to fulfil the right to breathe clean air. Air pollution has not been solved in any region, but there have been remarkable decreases in emissions and pollutant concentrations in many European countries, as well as the USA, Canada and Japan, where strong policies, regulations and regular monitoring systems were put into place.

O₃ is formed in the troposphere, near the Earth’s surface, when certain precursor pollutants react in the presence of sunlight. Entering into force in 1983, the Convention laid down the general principles of international cooperation for air pollution reduction and set up an institutional framework that has brought together science and policy. That percentage falls to 49 in high-income countries. Sulphur dioxide (SO 2) and nitrogen oxides (NOx) react with water in the atmosphere, producing sulphuric acid and nitric acid that return to earth as ‘acid rain’. These multiple choice questions on Air Pollution are very useful for SSC, UPSC etc. 4. In 1979, 32 countries signed the UNECE Convention on Long-range Transboundary Air Pollution: the first international treaty to deal with air pollution on a broad regional basis. This is because high quality monitors are expensive, as is the cost of training people to run and maintain monitoring networks. One of the most common sources of air pollution in rural and peri-urban areas of low-income countries, comes from households burning biomass, other solid fuels (e.g. Since then, air quality in the UK has improved remarkably. Many SLCP reduction measures also reduce other air pollutants, like nitrogen oxides. But air pollution is now inequitably affecting people in low- and middle-income countries. These impacts also disproportionately affect the most vulnerable people and communities. Within a city, areas closest to large sources can have huge pollutant concentrations, while other areas of the same city can be much cleaner. Scientific cooperation has also been initiated in Asia, and the Acid Deposition Monitoring Network in East Asia (EANET) has been building capacity and cooperation on monitoring across East and Southeast Asia. 2. The Convention counts on a solid science-policy interface, a compliance mechanism and a capacity-building support programme. While all individuals experience different levels of health impacts from air pollution, across large city or country populations, there is no evidence of a completely safe level of air pollution, especially in the case of particulate matter. which is a major pollutant of air.
