Mlnesoli properties of 15 abandoned mlne land sites In West Vlrginia Johnson, C. D. and Skousen, J. G. J. Environ. Qual., 1995, 24, (4), 635-643. The characteristics of minesoils on abandoned mine land often dictate which plant species will invade and establish from nearby undisturbed areas. The study measured physical and chemical minesoil properties on 15 abandoned mine sites in northern West Virginia and matched these properties to vegetation cover. 96100994

Mlnimlzatlon of flue gas emissions Delaby, 0. and Smith, R. Process Saf: Environ. Pror., 1995, 73, 21-32. The paper discusses flue gas emissions resulting from the combustion of fuel to provide process heat and power which are a major source of pollution. Carbon dioxide, oxides of sulphur, oxides of nitrogen and particulates contribute in various ways to the-greenhouse effect, acid rain-and smog. Presents a method which allows the best combination of measures to be used to achieve a target reduction in emissions at minimum cost. 96100995

Mlnlng disasters caused and controled by mankind: The case for coal mining and other minerals. Part 1. Causes of mining disasters Ramani, R. V. Natural Resources Forum, Aug. 1995, 19, (3), 233-242. In Part 1 of this two-part paper, the characteristics of mine disasters and their effects are presented with case studies from coal, metal and non-metal mines leading to an amplification of their causes and opportunities for control. The disasters discussed encompass those which threaten the health and the safetv of miners and those which affect the general uooulation. In part 2 of the paper, which will be published in the N&embe;1$95 issue of Natural Resources Forum, the approaches to hazard and disaster control are reviewed with particular atteniion to laws and regulations to promote health and safety at the workplace. 96100996

Model calculations of competing climatic effects of SC+ and CO, In fossil fuel combustion RaJeevan, M. er al., Curr. Sci., 1995, 68, (12), 1226-1231. Fossil fuel combustion has two competing effects on the climate system, warming due to CO, and other trace gas emissions, and cooling due to SOd2’particles formed from SO, emissions. A detailed parameterization of the relationship between fossil fuel burning and the So2 effect on backscattering and cloud albedo was implemented in a 1-dimensional, radiative-convective model to assess the climatic impact. The results showed that currently cooling induced by the combined effect of SO, completely counteracts the CO, greehouse warming. 96100996

Mortality of mallgnant tumors among occupatlonal radlatlon workers at_CIAE Jianhua. T. et al., Prowess in Nuclear Energy, 1994, 28, (l), 87-89. In the held of radiolo&al health, there is &I interest in ‘the effect of radiation on human beings, especially, the carcinogenic effect of small dose occupational exposure. The paper presents some results in this aspect. The mortality of malignant tumours among occupational radiation workers at CIAE (China Institute of Atomic Energy) from 1973 to 1985 was investigated using historical prospective study.

M. et al., Environment In!., 1995, 21, (5), 551-556. Modelling and parameter estimation in nucrobiological systems are prerequisites for predicting and controlling processes such as wastewater treatments, production of useful intermediates of commercial interest, determination of the fate of toxic compound in the groundwater, etc. Biological treatment of contaminated aqmfers is receiving increasing interest due to the widespread problem of groundwater contamination with oil products. Assessing the biodegradation kinetics of these compounds is essential in redicting the extent 10 which contamination will spread and in estimating tg e duration of in situ biodegradation cleanup operation. Many of the monoaromatic compounds found in gasoline (es ecially under aerobic conditions) can be degraded by the microorganism Pound in the soil and in the grounwater. NO. dispatch as a compliance strategy: 96101004 .~ The effect of alternative regulations Leppitsch, M. J. and Hobbs, B. F. Proc. Am. Power Conf, 1995,57, (2), 1572-1576. The paper reports that NO, constraint policies are now being formulated to attain CAAA compliance. The effects on systems dispatch and production costs will be significant. Of the different approaches to emissions limitations, a contrast between rate limits and tonnage caps is made. NRPB cuts up the cut-off theory 96101005 Kovan,D. NuclearEngng. Int., Dec. 1995, 40, (497), p. 15. Reports that according to the National Radiological Protection Board (NRPB), there is little biological evidence to support the existence of a threshold level below which there is nil possibility of developing cancer. This review of risks from low doses comes in the wake of controversy which has built up since the International Commission on Radiological Protection reduced its estimates of risk in its 1990 recommendations. Nuclide transport of decay chain In the fractured 96101006 rock medium: A model usmg continuous time Markov process Lee, Y. M. and Lee, K. J. Ann. Nucl. Energy, Feb. 1995, 22, (2), 71-84. A model suine continuous time Markov orocess for nuclide transoort of decay chain 07 arbitrary length in the f&tured rock medium his been developed. Considering the fracture in the rock matrix as a finite number of compahments, the transition probability for nuclide from the transition intensity between and out of the compartments is represented utilizing Chapman-Kolmogorov equation, with which the expectation and the variance of nuclide distribution for the fractured rock medium could be obtained. A comparison between continuous time Markov process model and available analytical solutions for the nuclide transport of three decay chains without rock matrix diffusion has been made showing comparatively good agreement.
