Air Pollution Emissions From Jet Engines [PDF]
Journal of the Air Pollution Control Association, 1968 Pollution emissions from three representative types of jet engines were determined. Pollutants measured included nitrogen oxides, aldehydes, carbon monoxide, hydrocarbons, and odors. A method is presented for determining the magnitude of pollution emissions due to commercial jet aircraft operation by using basic emission factors.

Exploring Deep Learning for Air Pollutant Emission Estimation [PDF]
Geoscientific Model Development, 2021 Abstract. The inaccuracy of anthropogenic emission inventory on a high-resolution scale due to insufficient basic data is one of the major reasons for the deviation between air quality model and observation results. A bottom-up approach, as a typical emission inventory estimation approach, requires a lot of human labor and material resources, and a top-

Emission Standards in Air Pollution [PDF]
American Journal of Public Health and the Nations Health, 1965 AN emission standard is a limit on the amount or concentration of a pollutant emitted from a source. The concentration of pollutant in the effluent may be stated subjectively in terms of its appearance to the eye or its odor, as determined by the nose; or objectively in terms of its weight or volume.
