Under the 11th Five Year Plan (FYP, 2006e2010) for national environmental protection by the Chinese government, the overarching goal for sulfur dioxide (SO2) controls is to achieve a total national emissions level of SO2 in 2010 10% lower than the level in 2005. A similar nitrogen oxides (NOx) emissions control plan is currently under development and could be enforced during the 12th FYP (2011e...

This paper reports the results of the investigation of air pollution from automobiles at intersections on some selected major roads in Ogbomoso, South Western, Nigeria. Four sampling routes were considered with ten sampling points (SP1 – SP10) placed 2.0m away from the edge of the road. Priority parameters: SO2, NOx, CO were monitored. The results of SO2, NOx, CO were in the range of 0.02 – 0.0...

The long-range transport of oxidized sulfur (sulfur dioxide (SO2) and sulfate) and oxidized nitrogen (nitrogen oxides (NOx) and nitrate) in East Asia is an area of increasing scientific interest and political concern. This paper reviews various published papers, including ground- and satellite-based observations and numerical simulations. The aim is to assess the status of the anthropogenic emi...

To gain a greater understanding of the spatial spillover effect of greenhouse gas emissions and their influencing factors, this paper provides a spatial analysis of four gas pollutants (CO2 emissions, SO2 emissions, NOx emissions, and dust emissions). Focusing on China, the paper also explores whether the four gas pollutants are influenced by the emissions of neighboring regions and other possi...

The effect of heterogeneous aqueous reactions on the secondary formation of inorganic aerosols during haze events was investigated by analysis of comprehensive measurements of aerosol composition and concentrations [e.g., particular matters (PM2.5), nitrate (NO3), sulfate (SO4), ammonium (NH4)], gas-phase precursors [e.g., nitrogen oxides (NOx), sulfur dioxide (SO2), and ozone (O3)], and releva...

Previous research works showed that to protect public health, the hospital incinerators should be provided with air pollution control devices. As most hospital incinerators do not possess such equipment, efficient methodologies should be developed to evaluate the safety of incineration procedure. Emission factors (EF) can be used for an easy estimation of legal parameters. Nevertheless, the act...

In India, air pollution is restricted mostly to urban areas, where automobiles are the major contributors and to a few other areas with a concentration of industries and thermal power plants. The major pollutants are CO, SO2 and NOx. The major sources of air pollution in the country are industries (toxic gases), thermal power plants (fly ash and sulfur dioxide) and motor vehicles (carbon monoxi...

Electron-beam fl ue gas treatment (EBFGT) technology has been applied in an industrial scale, EPS Pomorzany [1]. High removal effi ciency of SO2 (>90%) and NOx (ca. 70%) was obtained at 8 kGy absorbed dose. NOx removal needs much bigger energy consumption than that for SO2. Therefore, there is a need to fi nd a way to decrease energy consumption for NOx removal in this process. Electron acceler...

China has experienced very rapid economic development in recent yearsUrban air has very high concentrations of various pollutants, including sulphur dioxide (SO2), oxides of nitrogen (NOx), ozone (O3) and particulate. This paper reviews the changes in air quality in the cities like Guangzhou over the past 15 years, and notes that a serious vehicular-related emissions problem has been superimpos...

We determined 24-hr average ambient concentrations of PM2.5 and its ionic and carbonaceous components in Steubenville, OH, between May 2000 and May 2002. We also determined daily average gaseous co-pollutant concentrations, meteorological conditions, and pollen and mold spore counts. Data were analyzed graphically and by linear regression and time series models. Multiple-day episodes of elevate...
