Greenhouse Gas and Air Pollutant Emissions from Composting [PDF]

open access: yesEnvironmental Science & Technology, 2023
Composting can divert organic waste from landfills, reduce landfill methane emissions, and recycle nutrients back to soils. However, the composting process is also a source of greenhouse gas and air pollutant emissions. Researchers, regulators, and policy decision-makers all rely on emissions estimates to develop local emissions inventories and weigh ...

Emission Standards in Air Pollution [PDF]

open access: yesAmerican 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.

Air Pollution Emissions From Jet Engines [PDF]

open access: yesJournal 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.
