Airshed

Air pollution from a factory in Nepal

An airshed is a geographical area where local topography and meteorology limit the dispersion of pollutants away from the area. They are formed by air masses moving across a landscape, thus influencing the atmospheric composition of that area. Their boundaries are loosely defined, but can be quantified. Airborne chemicals disperse throughout an airshed and enter bodies of water in the area.[1]
