Document Summary
1/31/17- uniformly and non-uniformly uniformly mixed- the damage caused does not depend on what pollutant is released non-uniformly mixed: damage depends in part on where source is located. In fact, a single source may cause different amounts of damage at different geographical locations. Cumulative and non-cumulative pollutants- some pollutants do not accumulate at first, but then start to accumulate once the assimilative capacity of a sink is reached. Point source- it is easy to identify where a pollutant is released and measure emissions leaving the point of discharge. Non-point source- specific release points are hard to identify (pesticide and fertilizer chemicals that end up in waterways) or measuring emissions is impractical. Localized pollutants- cause pollution to a confined area (do not travel) Global pollutants do, like air pollution for instance (leaving a hole in the ozone layer) Continuous and episodic pollutants- emissions from power plants, automobiles, and households occur on a roughly continuous basis.
