Emissions of air-borne mercury from five municipal solid waste landfills in Guiyang and Wuhan, China
air-borne mercury five municipal solid waste landfills Guiyang Wuhan
2010/8/12
China disposes of bulk Municipal Solid Waste (MSW) by landfilling, resulting in a large quantity of mercury that enters landfills through waste. A detailed study on atmospheric mercury emissions from ...
The net climate impact of coal-fired power plant emissions
The net climate impact coal-fired power plant
2010/8/12
Coal-fired power plants influence climate via both the emission of long-lived carbon dioxide (CO2) and short-lived ozone and aerosol precursors. Using a climate model, we perform the first study of th...
Influences of Traffic Emissions and Meteorological Conditions on Ambient PM10 and PM2.5 Levels at a Highway Toll Station
PM10 PM2.5 Traffic emission Meteorological condition Highway toll station
2016/3/29
The PM10 and PM2.5 levels at a highway toll station were monitored from October to December 2008. Experimental results
show that hourly average PM10 and PM2.5 levels at the highway toll station were ...
Uncertainties in estimating mercury emissions from coal-fired power plants in China
mercury emissions coal-fired power plants China
2010/8/12
A detailed multiple-year inventory of mercury emissions from anthropogenic activities in China has been developed. Coal combustion and nonferrous metals production continue to be the two leading mercu...
Molecular characterization of urban organic aerosol in tropical India: contributions of primary emissions and secondary photooxidation
Molecular characterization urban organic aerosol tropical India primary emissions secondary photooxidation
2010/8/12
Organic molecular composition of PM10 samples, collected at Chennai in tropical India, was studied using capillary gas chromatography/mass spectrometry. Fourteen organic compound classes were detected...
Wet scavenging of SO2 emissions around India's largest lignite based power plant
Wet scavenging SO2 emissions India's largest lignite based power plant
2010/9/10
The Neyveli Lignite Corporation (NLC) is among the largest lignite based power plants in South East Asia. The four elevated stacks from this power plant emanate a substantial amount of sulphur dioxide...
Linking urban aerosol fluxes in street canyons to larger scale emissions

2010/3/16
In this study we investigate ultrafine particle (UFP) fluxes using a first order eddy viscosity turbulence closure Computational Fluid Dynamics (CFD) model and determine the different factors that inf...
Estimates of biomass burning emissions in tropical Asia based on satellite-derived data
Estimates biomass burning emissions tropical Asia satellite-derived data
2010/3/16
Biomass burning in tropical Asia emits large amounts of trace gases and particulate matter into the atmosphere, which has significant implications for atmospheric chemistry and climatic change. In thi...
A numerical evaluation of global oceanic emissions of α-pinene and isoprene
global oceanic emissions α-pinene isoprene
2010/2/21
A numerical evaluation of global oceanic emissions of α-pinene and isoprene based on both "bottom-up" and "top-down" methods is presented. We infer that the global "bottom-up" oceanic emissions of α-p...
