Schematic drawing, causes and effects of air pollution: (1) greenhouse effect, (2) particulate contamination, (3) increased UV radiation, (4) acid rain, (5) increased ground-level ozone concentration, (6) increased levels of nitrogen oxides. An air pollutant is a material in the air that can have many effects on humans and the ecosystem. [64]
While the effects of air pollution on the respiratory diseases are well understood, air pollution also affects the cardiovascular system at the same level as or higher level than the respiratory system, [34] and the adverse cardiovascular health outcomes in both children and adults are high when exposed to air pollution. Carbon monoxide, oxides ...
Aircraft engines produce gases, noise, and particulates from fossil fuel combustion, raising environmental concerns over their global effects and their effects on local air quality. [2] Jet airliners contribute to climate change by emitting carbon dioxide (CO 2 ), the best understood greenhouse gas , and, with less scientific understanding ...
Benjamin Greeley Ferris Jr. (24 January 1919 – 1 August 1996) [1] [2] was an American physician and epidemiologist, a professor at Harvard School of Public Health who helped to pioneer statistical studies into the health effects of air pollution in the United States in the 1960s and 1970s.
Long-term exposure to fine particulate pollution may increase the risk of developing dementia, new research says. Dementia risk grows with increased exposure to air pollution, study finds Skip to ...
Various definitions of pollution exist, which may or may not recognize certain types, such as noise pollution or greenhouse gases.The United States Environmental Protection Administration defines pollution as "Any substances in water, soil, or air that degrade the natural quality of the environment, offend the senses of sight, taste, or smell, or cause a health hazard.
Air pollution can affect nearly every organ and system of the body, negatively affecting nature and humans alike. Air pollution is a particularly big problem in emerging and developing countries, where global environmental standards often cannot be met. The data in this list refers only to outdoor air quality and not indoor air quality, which ...
Building effects or downwash: When an air pollution plume flows over nearby buildings or other structures, turbulent eddies are formed in the downwind side of the building. Those eddies cause a plume from a stack source located within about five times the height of a nearby building or structure to be forced down to the ground much sooner than ...
