S. er aZ., Combusrion & Flame, Jan. 1995, 100, (l), 11-20. The homogeneous, gas-phase formation of polychlorinated dibenzo-pdioxins and polybrominated dibenzo-p-dioxins has been observed from the high-temperature thermal decomposition of 2,4,6-trichlorophenol and 2,4,6-tribromophenol, respectively. Experiments were conducted in a l.Ocm.i.d. flow reactor over a temperature range of 300”-800°C with reactant concentrations of approximately 3.0 X lo” mol/L in a reaction atmosphere of dry air.

The objective of this study is to develop a better understanding of the collection characteristics of dust measurement instruments used in mine dust control research with respect to properties of quartz and coal dust. 95103062 Land contamlnatlon Is all washed up Keegan, C. P. and Dietrich, A. J. Nuclear Engineering Int., Jan.-Feb. 1995, 40, (488), 39-40. In land remediation there is the common perception that soil washing is a technology that is still in its infancy. This may be changing with the development of a new washing system that could have a major impact on the remediation industry. The technology has been developed by Scientific Ecology Group, a Westinghouse subsidiary, and the Westinghouse Science and Technology Center, which provides an alternative to the usual methods (incineration, stabilisation or landfilling) for treating large volumes of contaminated materials. It is applicable to soil contammated with radioactive, hazardous, toxic and mixed waste.

The ideas of secondary school children concerning ozone layer damage Boyes, E. and Stanisstreet, M. Global Environmental Change, Dec. 1994, 4.7 141~ '311.324. \.I’ ----.. The understanding of pupils between the ages of 11 and 16 about the ozone layer - what it is, what will damage it and what will be the likely result of such damage - has been studied. Following the use of a preliminary openform questionnaire, the ideas of a large cohort of children have been probed by closed-form questionnaire and by interviews with a subset of this Prouu. The authors exulain that most ouoils seem aware that the ozone laye;is a layer of gas ardund Earth, but’less sure what that gas is. They also know that it protects Earth from ultra-violet rays from the sun, and that further depletion will allow more ultra-violet to Earth and cause more skin cancer. The authors provide evidence to suggest that such confusion of ideas is strongly held and that, even with this relatively new and abstract phenomenon, icie& are held in a consistent similar framework by most pupils.

Methand is the most abundant organic chemical in the earth’s atmosphere, and its abundance is increasing with time and has reached levels not seen in recent geological history. Methane is produced both naturally and anthropogenically. One of the sources of anthropogenic methane is manure from domesticated animals. A methodology had previously been developed to estimate the amount of methane generated from this source. This was done by estimating the methane -conversion factor (MCF’) typically achieved by various waste management systems. The present study was conducted to evaluate these MCF assumptions using dairy manure as the representative livestock manure.
