Are airplanes and a busy highway point source or nonpoint source pollution?

    For airplanes it depends on the modelisation and its purpose.

    Highway are obviously not a point. So I fail to imagine any case in which someone could decide to modelize a highway as a point

    If you had said "cars stucked in an highway" it could have been different. Someone could decide to create a model in which all cars are modelized as - moving point source - in which case the pollution source from the highway are a set of points. But in that case, it is not the highway itself the source, but the cars.

    Such a modelisation could be useful, for example, if you want to study how much a driver is intoxicated when driving on a busy highway; what is the influence of speed and traffic on that intoxication; or open windows.

    For airplaines, likewise: if what you want to study is the distribution of pollution in the clouds because of plane trails (or, if you are into conspiracy theories, a simulator for chemtrails :D), then you would probably want to consider each plane as a point source. And then plug your model on a planeWatch API, and see if that is coherent with the chemtrail conspiracist claims.

    But generally speaking, if the idea is the more usual computation of maps of pollutions, then you will probably want to consider highway, and airport as lines or area sources, and plane routes as well

    They are non-point sources of pollution because vehicles and planes move.
