Air pollution is an example of a public bad. A public bad, in economics, is the symmetrical opposite of a public good. Air pollution is the most obvious example since it is non-excludable and non-rival, and negatively affects welfare.
Nonpoint source air pollution affects air quality, from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a nonpoint source of pollution; if the discharges were to occur to a body of water or into the ...
air pollution - the modification of the natural characteristics of the atmosphere by a chemical, particulate matter, or biological agent. albedo - reflectance; the ratio of light from the Sun that is reflected by the Earth's surface, to the light received by it. Unreflected light is converted to infrared radiation (heat), which causes ...
Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
In meteorology, an inversion (or temperature inversion) is a phenomenon in which a layer of warmer air overlies cooler air. Normally, air temperature gradually decreases as altitude increases, but this relationship is reversed in an inversion. [2] An inversion traps air pollution, such as smog, near the ground.
Water pollution point sources Air pollution point sources. A point source of pollution is a single identifiable source of air, water, thermal, noise or light pollution.A point source has negligible extent, distinguishing it from other pollution source geometrics (such as nonpoint source or area source).

A pollutant or novel entity [1] is a substance or energy introduced into the environment that has undesired effect, or adversely affects the usefulness of a resource. These can be both naturally forming (i.e. minerals or extracted compounds like oil) or anthropogenic in origin (i.e. manufactured materials or byproducts).
