Tomb, T. F. et al., Appl. Occup. Environ. Hyg., 1995, 10, (12), 1019-1026. Reports that the Mine Safety and Health Administration (MSHA) yearly performs quartz analysis on -9ooo respirable coal mine dust samples collected for various occu ations in US coal mines. All occupational quartz exposure data collecte s by MSHA since 1985 have been compiled and analyzed to characterize current occupational exposures to quartz.

Carbon dioxide production from coal-fired power plants for enhanced oil recovery: A feaslblllty_ study- in Western Canada
96106672
Tontiwachwuthikul, P. et al., Energy, Oct. 1996, 21, (lo), 857-869. In order to sustain the current production ca acity of conventional oil in Western Canada, enhanced oil recovery ( l$OR) technologies must be increasingly applied. Among these, CO, flooding is a highly attractive alternative. A large amount of CO, is bemg produced by coal-fired power plants in this region. The CO, is currently discharged into the atmosphere and could be a major contributor to the greenhouse effect, which may lead to global warming. Thus, the concept of capturing CO, and utilizing it as a flooding agent in EOR processes is currently generating much interest among oil, utility and coal companies. The authors demonstrate how cogeneration conce ts, together with process optimization strategies, help to reduce CO?-pro Buction cost by utilizing low-pressure steam and water heat from various sections.

Assessment of the radiation field from radioactive elements In a wood-ash-treated coniferous forest in Southwest Sweden
96106565
Ravila. A. and Helm. E. J. Environ. Radioactivirv. ,I Jul.-Aue.Y 1996. ,I 32. (l), l+-156. The distribution of natural and antrophogenic radioactive elements in soil and wood was investigated in a 30-year-old forest stand of Norway spruce. Forest plots treated w$h a single dose of granulated wood ash in 198g were compared with untreated control plots. It was observed that the retention of radiocaesium and radiostrontium by the forest soil is rather strong in spite of the high annual precipitation and the relatively acidic conditions of the soil. Most of the deposited nuclear weapons fall-out of radiocaesium and radiostrontium is still residing in the forest soil.
Batteries escape the scrap heap 96106566 Barthorpe, F. Prof. Engng., Apr. 1996, 9, (7), 26-27. Reports that a working group under the auspices of the European Portable Battery Association has carried out trials which show that it is technically feasible to use metal industry processes to recycle household batteries at only a fraction of the cost of dedicated battery recycling processes.

Owens, P. N. et al., J. Environ. Radioactivity, 1996, 32, (3), 169-191. The use of “‘Cs measurements for investigating soil erosion and sediment redistribution within the landscape is now well established. However, for this ootential to be fullv realised. and to intemret the results obtained from such’investigations in ; meaningful manner ‘it is im ortant to understand how bomb-derived “‘Cs fallout interacted with partic Pes at the soil surface. Furthermore, as it is the surface soil which is tiobilised by most wind and water erosion processes, it is important to determine how the “‘Cs content as the surface as changed over time. The oaoer renorts a series of field and laboratory experiment which were carridd but td provide empirical information on the fate of “‘Cs applied to different soil types to simulate fallout during individual storm events and over a 10 month period. 96106566 Better balanced buildings Wyatt, T. Heat. Air Cot&t.. Aor. 1996. 14-18. Tde author points out that if reduced energy consumption leads to an inadequate indoor climate, the consequent productivity losses will be many times more expensive than the energy costs. A diagram presents order of magnitude of absenteeism from workplaces due to respiratory ailments. Research shows that the small cost of roviding the ideal indoor climate is about the same as that of providing Pree tea or coffee to the workforce. Describes design features of better buildings.

Jayadevappa, R. and Sumedha, C. The J. of Energy & Development, 20, (2), 229-246. Giobal climate change has become one of the most important of recent issues. It is estimated that roughly 60% of projected global climate change will be caused directly by the energy &or.-Develzping nations are tf;e fastest rowing reenhouse gas (GHG) emission sources. The restricted focus o P the GH E problem to fossil fuels and carbon dioxide emissions in particular frightens the developing countries. Most studies on global climate change neglect the impact of proposed measures of carbon tax on the economies of developing bloc. In this paper the authors examine the impacts of implementing a carbon emission tax on the economy of India using an input-output model. After discussing the economywide impacts of a carbon emission tax, possible measures for combating global climate change are examined.

96106676 Clean-up of urban areas in the CIS countries contaminated by Chernobyl fallout r;;_+Ii and Andersson, K. G. J. Environ. Radioactivity, 1996, 33, (2), Earlier investigations in the CIS (the former Soviet Union) showed that the radiation from urban surfaces contaminated by Chernobyl fallout was almost entirely due to 13’Cs. Following a series of small-scale tests, several decontamination methods were selected for field trials in Russia and Ukraine. The trials revealed that, even after 7 years, up to 75% of the ‘“Cs could be removed at relatively little cost and more could be removed if necessary.
