The study was conducted around the Jayant Coal Mine situee in the Sidhi district of Madhya Pradesh, India. Concentrations of Si, Cr, and Pb in total suspended particulates, settled dusts, foliar dusts, foliary tissues, and soil systems were quantified at mine spoils, residerma areas, and major road sites in the mining areas. Maximum concentrations of heavy metals were observed at road sites and minimum in the residential areas.

In 1993, -20 million tons of flue gas desulphurization (FGD) material was generated by electric power generating facilities equipped with wet lime- limestone FGD systems (scrubbers), Of this material, x5%, known as syn- thetic gypsum, was used as a substitute for natural crude gypsum, for agricultural uses and wallboard and cement production. This synthetic gyp- sum represents ~4% of total gypsum consumed by the industry, and -5% of crude gypsum mined in the US. Provisions of the Clean Air Act Amend- ments of 1990, calling for a 2-phase reduction of SO, .emissions, have generated considerable interest, discussion and research m FGD byprod- ucts from coal burning electric utilities.

The paper evaluates the British government’s current (and five-year old) campaign for energy conservation, ‘Helping the Earth Begins at Home’. The paper starts by reviewing some of the arguments which can be used to support this type of policy initiative which, on the face of it, urges people to consider the global implications of local actions. The argument then turns to focus upon the ideaological work that was invested into the pro- duction of the campaign, and in particular the redefinition of legitimate concern (for the global) and legitimate sites of activity (the local). Follow- ing this, the paper investigates the ways in which the campaign was con- sumed (read, ignored, rejected, acted upon) by members of the public. Long interview transcripts with householders in Bristol, UK, are analysed and represented to illustrate the weaknesses of the campaign.

A better understanding of the pyrolysis and combustion of chlorinated hydrocarbons (CHCs) remains of considerable practical and fundamental importance. As the last of four papers of detailed product analyses of the pyrolysis of unsaturated CHCs, the authors present the results of the high- temperature, oxygen-free pyrolysis of hexachlorobutadiene (C,C&) from 573 to 1273 K.

Kinetic studies on the formation of CO, hydrate on the surface of a Ii uid CO? droplet in water were conducted. Dimensionless equations for the E O2 hydration on the surface of a liquid CO? droplet were obtained. The thick- ness of the CO: hydrate was investigated in terms of the diffusion coeffi- cient, reaction rate constant, and radius of droplet by the use of dimensionless equations.

In order to reduce the toxicity of municipal solid waste incinerator fly ash containine PCDD and PCDF. flv ash was hvdrothermallv treated. Under hydrothehal conditions, conceniration of PcDDs and PcDFs decreased due to dechlorination reaction. This reaction occurred more effectively with high temperature and alkaline ingredients with/without methanol in solvent. It was found that PCDDs/PCDFs decomposed almost corn letely and the toxicity of treated ash decreased to 0.03 ng-TEQ/g at 573 I& m 20 minutes with the solvent of 1N KaOH solution containing 10 ~01% methanol.

Measurements for polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs, PCDFs) were carried out in flue gas and fly ash formed after coal combustion in a power plant at the Nitrogen Works in Tarnow, Poland.

96105559 Long radloactlve decay chains and stiffness problems Para, A. F. and Sanjust, V. Ann. Nucl. Energy, Jun. 1996. 23, (9). 185-789. The time evolution of the nuclide inventory of nuclear waste is of interest in many problems, and it is often required at very long times; the heavy nuclides involved pertain to the four actinides series and the wide dispari- ties in their half-lives gives well known numerical difficulties. In the paper the adopted procedure is described.
