96/03154 A comparative study on radloeaesium (131es) uptake from coniferous forest soli Fawaris, B. H. and Johanson, K. 1. 1. Environ. Radioactivity, 1995,28, (3), 313-326. Studies related to mechanisms that were expected to influence the behaviour, uptake, transfer and sorption processes of fission products within soils of agricultural farming land have received much attention during the last 40 years. In contrast, the dynamic processes that may influence mobility and transfer mechanisms of such fission products in soils of the forest ecosystems have not been studied or understood to such an extent, and require more investigation. The aim of this study was to investigate and compare the uptake of 1lJCs by sheep fescue in pot experiments and field plants growinji in coniferous forest soil in order to obtain a better understanding of 1 Cs uptake, and to evaluate the influence of different soil parameters on 1lJCs uptake.

96/03155 Complex registration of flow paths and matter transport from a disposal sIte located In an open-cast mine. Case study Hufelsensee (Germany) Dermitzel, J. et al., Z. Geol. Wiss., 1995,23, (1), 147-162. (In German) The influence of a landfill located in a brown-coal open-cast mine residual pit on groundwater and on the residual lake separated from the landfill by an earth wall was studied by geophysics, isotopic, and chemical measurements. Contaminations were only observed in the Tertiary aquifer, whereas the emission paths from the landfill do not pass through the lake. The investigations are the first step to characterize the behaviour of landfill bodies located below or in the same level of neighbouring aquifers.

96/03158 Contaminated land - A discussion of risk, standards and 'trigger values' Watkinson, R. J. Petroleum Review, Jan, 1996, 50, (588), 36-38. In the last two decades there have been some prominent cases where chemical wastes have contaminated sites (Love Canal and Lekkerkerk in The Netherlands). Discusses how these incidents have focused attention on the issue of risks associated with the exposure of humans to polluted soil and the need to protect this environment.

96/03159 Continuous removal of sulfur oxides at ambient temperature, using activated carbon fibers and particulates Fei, Y. et al. Prepr. Pap-Am. Chem. Soc., Div. Fuel Chem. 1995, 40, (4), 1051-1055. Discusses the catalytic performance of fibrous and particulate activated carbons obtained from different precursors for S02 removal at ambient temperatures, using a humidified model flue gas.

96/03160 Contrasting geographical distrIbution of mortality from pneumoconiosis and chronic bronchitis and emphysema in BritiSh coal miners Coggon, D. et al., Occup. Environ. Med. 1995, 52, (8), 554-55, To explore whether the characteristics of coal mine dust that predispose to chronic airways obstruction are the same as those associated with pneumoconiosis, mortality from the two diseases was compared in coal miners in 22 counties of England and Wales during 1979-80 and 1982-90. The findings indicate that the pathogenetic mechanisms by which coal mine dust causes chronic bronchitis and emphysema depend on different features of the dust from those producing pneumoconosis. Also, they suggest that current social security regulations in the UK, which requires evidence of pneumoconiosis as a condition of compensation for chronic bronchitis and emphysema in coal miners, may discriminate unfairly against claimants from some regions.

VGB Kraftwerkstech., 1995. 75, (2), 141-144. (In German) Discusses the combustion of waste in coal-fired power plants with respect to German legislation, waste gas purification, technical problems. and public acceptance.

96/03162 COPATH- A spreadsheet model for the estimation of carbon flows associated with the use of forest resources Makundi, W, R, et al., Biomass & Bioenergy, 1995, 8, (5), 369·380, The forest sector plays a key role in the global climate change process, A significant amount of net greenhouse gas emissions emanate from land use changes, and the sector offers a unique opportunity to sequester carbon in vegetation, detritus, soils and forest products, However, the estimates of carbon flows associated with the use of forest resources have been quite imprecise. The paper describes a methodological framework - COPATHwhich is a spreadsheet model for estimating carbon emissions and sequestration from deforestation and harvesting of forests.

96/03163 The cost of cutting carbon emissions - A csse study of Western Europe Krause, F, and Koomey, 1. Energy Convers, Mgmi. Juri-Aug. 1996, 37, (6), 973-978. Based on a study of five core EU countries (EU-5 France, Germany, Italy, the Netherlands, United Kingdom) and extensive sensitivity analyses, it is found that a climate-oriented policy programme could reduce year 2020 EU-5 carbon emissions by as much as 60% below 1985 levels without relying on nuclear power or increased use of natural gas. It is found that a climate-oriented policy programme could lower year 2020 expenditures for energy services by 40-60 billion ECU below the level implied in the business-as-usual projections of the European Commission, Including several economic and environmental double dividends, total annual savings are estimated to be more than 2% of gnp,
