Emission characteristics of nonmethane hydrocarbons from private cars and taxis at different driving speeds in Hong Kong [PDF]
, 2011 Vehicular emissions are the major sources of a number of air pollutants including nonmethane hydrocarbons (NMHCs) in urban area. The emission composition and emission factors of NMHCs from vehicles are currently lacking in Hong Kong.

International Journal of Environmental Research and Public Health, 2022 Fertilizers are made from manure, but they are also produced through chemical processes. Fertilizer is an ammonia emission source; it releases ammonia when used. Ammonia is also emitted during the production process. Although many studies related to fertilizer application have been conducted, there are few research cases related to the production ...

Emission factor of ammonia (NH3) from on-road vehicles in China: tunnel tests in urban Guangzhou
Environmental Research Letters, 2014 Ammonia (NH _3 ) is the primary alkaline gas in the atmosphere that contributes to formation of secondary particles. Emission of NH _3 from vehicles, particularly gasoline powered light duty vehicles equipped with three-way catalysts, is regarded as an ...

Interpreting broad emission-line variations I : Factors influencing the emission-line response
, 2014 We investigate the sensitivity of the measured broad emission-line responsivity dlog f_line/dlog f_cont to continuum variations in the context of straw-man BLR geometries of varying size with fixed BLR boundaries, and for which the intrinsic emission ...

Rice Agriculture: Factors Controlling Emissions
, 1993 Recent atmospheric measurements indicate that concentrations of greenhouse gases are increasing. Atmospheric methane concentration has increased at about 1% annually to 1.7 ppmV during the last decades (Khalil and Rasmussen, 1987). The resulting effect on global temperature is highly significant because the warming efficiency of methane is up to 30 ...
