The mobility of Cd, Co, Cu, Ni, Pb, Sb, and Zn from six different coalfired power plant fly ashes that show a wide compositional range was examined using a sequential extraction procedure in order to assess their mobility when these wastes are ponded or landfilled. The results reveal differences in the total contents of the selected trace elements among the fly ash samples, which must be related to differences in coal composition and combustion technology. 95lO3072 N,O emlsslons from anthropogenlc sources In the Federal Republic of Germany Schoeo, M. and Walz, R. Nova Acto Leopold, 1994, 70, (288). 349-354. The total anthropogeoic emissions of NO, in Germany are estimated roughly at 200-300 kt/yr. The main emission sources identified are agriculture (including a minor contribution from animal wastes) and the production of adipic acid, the latter possibly being reducible by means of a new catalytic process. These two sources are presently contributing to the total emissions each with a share of roughly 30-40%. Surface water and ground water sources follow with a share of 10-u)%. Combustion of fossil fuels produces up to 10% of the emission, caused mainly by combustion of coal. 95103073 New knowledge of the assessment of coal mlne dust Glue&auf, 1994, 130, (2), 111-114.

The exhaust from a direct-injection light-duty diesel engine was sampled for polycyclic aromatic compounds (PAC) at three constant speeds and at five load settings for each speed, using a total-exhaust solvent-stripping apparatus. Exhaust samples were analysed for 3- and 4-ring polycyclic aromatic hydrocarbon (PAH) and dibenzothiopheoe by g.c.-m.s. in electron-impact mode. The PAC recoveries (per cent of fuel PAC) were highest at low loads and progressively declined with increasing load.

A numerical model is presented, based on the local volume averaging formulation of transport phenomena in porous media, for simulating meltwater infiltration into unsaturated, frozen soil. With the defined flow and freezing boundary conditions at the snow-soil interface, using the concept of a surface local averaging volume, the time variation in profiles of temperature, liquid/ice content, infiltration/percolation rates, ahd rate of phase change in upper soil layers are predicted.

Institute ofEnergy, Mar. 1995,68, (474), The paper presents the results of combustion tests on Greek lignite in two CFBC (circulating fluidised bed combustor) facilities. The first, a laboratory-scale facility of approximately 100 kW thermal power, is at NTUA (the National Technical University of Athens); the second, which is of semi-industrial scale (1.2 MW thermal power), is at RWE’s power station at Niederaussem in Germany. The two installations are of different size and different design, and the concepts represent the major CFBC coostructioo trends; the Niederaussem facdity operates with thermally insulated (‘hot’) cyclone, whereas the CFBC in Athens features a non-insulated (‘cold’) cyclone.

Nuclear News, Feb. 1995, 38, (2), p. 28. Describes a new patented process which has been successful in removing radioactive elements from nuclear waste, and may someday be used for groundwater cleanup and for cleaning leaking fuel basins. The processing, using ion exchange columns, removes highly radioactive plutonium, cesium, and strontium from liquid waste stored in large tanks, so that waste is less hazardous and can be treated for disposal.
