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. [61]
Air pollution — Atmospheric particulate matter • Biological effects of UV exposure • CFC • Environmental impact of the coal industry • Environmental impact of hydraulic fracturing • Indoor air quality • Ozone depletion • Smog • Tropospheric ozone • Volatile organic compound • Ultrafine particles Light pollution Noise pollution
This creates air pollution, including nitrous oxides and particulates, and is a significant contributor to global warming through emission of carbon dioxide, [276] for which transport is the fastest-growing emission sector. [277] By subsector, road transport is the largest contributor to global warming. [276]
A 2004 study commissioned by environmental groups, but contested by the United States Environmental Protection Agency, concluded that coal burning costs 24,000 lives a year in the United States. [30] More recently, an academic study estimated that the premature deaths from coal related air pollution was about 52,000 each year. [31]
The health and environmental impact of transport is significant because transport burns most of the world's petroleum.This causes illness and deaths from air pollution, including nitrous oxides and particulates, and is a significant cause of climate change through emission of carbon dioxide.
These sections require the EPA "(1) to list widespread air pollutants that reasonably may be expected to endanger public health or welfare; (2) to issue air quality criteria for them that assess the latest available scientific information on nature and effects of ambient exposure to them; (3) to set primary NAAQS to protect human health with ...
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 ...
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 ...
