Igarashi, Y. et al., J. Environ. Radioactivity, 1996, 31, (2), 157-169. Recent observations of WSr and 13’Cs deposition at the Meteorolog$aI Research Institute, Tsukuba, are presented. The annual deposition of Sr and 13’Cs in the 1990s was around 0.15 and 0.3 Bq rn., respectively. Although a spring eak was found in the deposition, it is difficult lo explain this seasona P pattern only by the stratospheric fallout. The annual deposition trend of I3 Cs was found IO be well fitted by the stratospheric constant and an additional constant term. The variation in the ratios of the radioactivity and corresponding stable elements did not show the maxima in the deposition peak months in Spring. Reduction of nltrlc oxlde by ectlvated carbons as 96105595 both support and reducing agent Gao, Z. et al., Cuihua Xuebao, 1996, 17, (2), 117-122. (In Chinese) The paper describes how activated carbons from coconut shell, hawthorn nut, mountain peach nut and coal were used in the reduction of NO as both support and reducing agents.

A. ef al., Energy & Environment, 1996, 7, (2), 209-222. The concentration of greenhouse gases in the atmosphere has risen substantially during the last 200 years. It is believed that this rise is mainly caused by the burning of fossil fuels and deforestation, and it may eventually result in global warming. In response lo thise issue, a number of nations have signed the Framework Convention on Climate Change which stipulates that greenhouse gas emissions have to be stabilized at the 1990 level by the year 2000. Describes how the government of the Netherlands went a step beyond this agreement and committed itself to achieving stabilization of CO, emissions at 1989 levels by the year 1994195 with a further 3-5% reduction by the year 2000.

Self-commitments as an effective Instrument for a 96105610 world-wlde climate protectlon Strassburg, W. and Heck, V. Energy & Environment, 1996, 7, (2), 169-178. Discusses how energy is a crucial feedstock for the welfare of the world’s people. In recent decades, energy has become a major world-wide interest, both because of the imernalionalization of irs resource distribution and the global commonality of its potential environmental effects, particularly the chance of climate changes from the emissions of greenhouse gases from the use of fossil fuels. .More and more it is becoming clear that it may not be the availabilily of natural resources which is the limiting overall factor, but our environment’s capacity 10 bear and absorb mankind’s activities. SF6 the warmlng signs 96105611 Dawn, T. Elec. Rev., Jan. 1996, 229, (2), 32-34. Discusses the influence of sulphur hexafluoride, which accumulates atmosphere by 7-9% per annum, on global warming.

Three fly ash extracts, of which two were fortified with different PCDF and PCDF congeners, were analyzed by eight different laboratories. The results show relatively good precision, RSD for levels reported as TEQs are below 25%. Problems with the analysis of 1,2,3,7,8,9-hexachlordibenzofuran was observed.

96/05615 Study of alrborne radloactlvlty near to the hlgh water mark at Drlgg Polnt Branford, D. and A’elis, P. M. J. Environ. Radioactivity, 1996, 31, (3), 237-251. Measurements are reported on radionuclides collected at Drigg Point using muslin screen aerosol colleclors arranged along two transects leading inland from the high water mark for approximately 300 m. The results of seven long-term exposures, taken over periods of 1.0-8.2 weeks, and three short-term exposures, taken over 1.5-2.2 h at different states of the tide, are presented.
