Needed research on the terrestrial effects of coal gasification and liquefaction technologies

The Terrestrial Effects panel discussed the needed direction and techniques for future research in the terrestrial effects of new coal conversion technologies. Panel members concurred on the need for changes in emphasis, approach, and even attitude in environmental research. The following are the basic perceptions of the panel: Our goal is to provide for environmentally amenable technologies in coal conversion and product distribution, especially focusing on pollutants entering pathways to man.… more

Atmospheric trace element pollutants from coal combustion

In summary, analyses have been obtained for approximately 60 elements for sized flyash particles from two coal-fired steam plants. Evaluation of data from the elemental analyses, including the concentration dependence upon particle size, electron microscopy, ESCA, and mass spectrometry suggests a mechanism for formation of the submicron particles in some coal-fired plants. This mechanism involves bursting of larger particles during gas expansion and production of a very large number of very sma… more
