Biomass burning (BB) is a large source of primary and secondary organic aerosols (POA and SOA). This study addresses the physical and chemical evolution of BB organic aerosols. Firstly, the evolution and lifetime of BB POA and SOA signatures observed with the Aerodyne Aerosol Mass Spectrometer are investigated, focusing on measurements at high-latitudes acquired during the 2008 NASA ARCTAS mission, in comparison to data from other field studies and from laboratory aging experiments. The parameter f60 , the ratio of the integrated signal at m/z 60 to the total signal in the organic component mass spectrum, is used as a …
If Ethanol Is The Answer, What Is The Question, Peter Z. Grossman
If Ethanol Is The Answer, What Is The Question, Peter Z. Grossman
Peter Z. Grossman
Since 2005, in the face of rising oil and gasoline prices, many Americans have looked to plant-based fuels, particularly ethanol, as the "answer" to our energy dilemmas. Section III examines the issues connected specifically to ethanol, how market forces as well as government subsidies have worked to make corn-based ethanol economically viable at times, why that viability has been lost in recent months even with subsidies, and further, why ethanol from corn on the scale the legislation demands is impractical. Clearly it would be technically possible to produce the mandated 15 billion gallons of ethanol, and distilling capacity will nearly …
The Microbial Pool And Soil Carbon Cycling On Reclaimed Surface Mine Sites, Alice Jones, Guy Evans, James Fox
The Microbial Pool And Soil Carbon Cycling On Reclaimed Surface Mine Sites, Alice Jones, Guy Evans, James Fox

The southern Appalachian region is an important source of coal resources. The wide scale practice of surface mining in this region leads to the landscape-scale removal of surface material and soils, a large carbon reservoir and important component of the carbon cycle. To date, few scientific studies have examined the development of the soil carbon cycle on post-reclamation mine sites in this region. In particular, development of the microbial pool and its role in carbon cycling in post-reclamation mine soils remains poorly understood. This study measured microbial biomass and soil respiration, as well as bulk soil total organic carbon, total …
