Article history: Received 1 October 2006 Received in revised form 20May 2007 Accepted 20 June 2007 Co-combustion of chicken litter (CL) with coal was performed in a laboratory-scale fluidized bed combustor to investigate the effect of CL combustion on pollutant emissions. The emissions of major gaseous pollutants including CO, SO2, H2S and NO and temperature distribution along the combustor wer...

The global flux of sulfur dioxide (SO2) emitted by passive volcanic degassing is a key parameter that constrains the fluxes of other volcanic gases (including carbon dioxide, CO2) and toxic trace metals (e.g., mercury). It is also a required input for atmospheric chemistry and climate models, since it impacts the tropospheric burden of sulfate aerosol, a major climate-forcing species. Despite i...

BACKGROUND Persistently high sulphur dioxide (SO2) emissions from platinum group metal (PGM) smelting pose a major threat to communities located around smelters. This paper examined SO2 emission trends, emission regulations and residents' perceived health risks from exposures to such emissions at Selous Metallurgical Complex (SMC) PGM smelting facility in Zimbabwe. METHODS SO2 data from roof ...

With the rapid development of the economy, the sulfur dioxide (SO2) emission from China since 2000 is of increasing concern. In this work, we first presented the change of SO2 emission in China since 2000 using a technology-based methodology. Then, we compared the SO2 emission data with a variety of official statistics, ground-based measurements and satellite observations of sulfur related quan...

The problem of soot emissions from diesel engines is introduced and the possible solution of combining doped perovskites and microwave (mw) irradiation to "clean up" diesel soot filters is outlined. Eighteen doped perovskite catalysts are synthesized and tested for propane and CO oxidation, which are taken as model components for soot. The activity, selectivity, and SO2 tolerance are compared u...

Total uncertainty in greenhouse gas (GHG) emissions changes over time due to “learning” and structural changes in GHG emissions. Understanding the uncertainty in GHG emissions over time is very important to better communicate uncertainty and to improve the setting of emission targets in the future. This is a diagnostic study divided into two parts. The first part analyses the historical change ...

This study evaluates the regional and sectoral CO2 emissions estimated by different CO2 emissions accounting methodologies around 2050 under different CO2 reduction scenarios. The production-based measurement of CO2 emissions is based on polluter pays principle, while the consumption-based measurement is based on beneficiary pays principle. In the field of global warming, the widely used method...
