Environ Radioactivity, 1995, 26, (2), 119-133. Edible winkles from Saltom Bay, Cumbria (north-eastern Irish Sea) had flesh ““PO concentrations in excess of 200 Bq Lg’ (wet). This came from liquid waste discharged under authorization from a chemical plant producing phos boric acid. This labellin of the winkles under natural conditions was exp P* cuted to determine the ‘40 depuration rate and biological halftime.

A senes of tests have been completed at the British Coal Research &tablishment on an atmospheric pressure spouted fluidized-bed gasifier aimed at reducing the alkali inetal &tent of ihe fuel gas to aroundb.1 ppm Na t K. The work has been completed in three phases. The aper describes the rationale to alkali control work in the British Coal # opping Cycle, the experimental work, and results of each of the phases.

._ ..,.

A process model has been developed which is able to predcit with confidence the sulohur-dioxidc removal nerformance of sorbent iniected into the furnace for &ntrol of SO,. The model requires limited inpit information on the boiler plant conditions and the sorbent. It has been validated against laborato and industrial-scale plant data, and gives a sood rediction of sulphur-a!loxidc removal for both limestone and dolomitic sor& n$. Therefok this model provides industrial plant designers and process operators with a valuable tool, enabling them to assess the rformance of in-iiunacc sorbent injection for their plant, as well as sep” ecting the most suitable sorbent and identifying the optimum location for the addition of aorbent. 95105357 Modern, scologlcally clean and hlghly sfflclsnt coal utilization technologies Nowak, W.

Emissions of N$ were mea&red d& the in&era&m of sewage sludges, originatmg from various municip 9 waste-water treatment plants, in stationary and circulating fluid&d-bed wmbustors. The mechanically de-watered sludges had a solids content of 20-3096 wt dm, and the pndried sludges had 87-9446 wt dm. Bituminous and brown coals were also investigated, for purposes of comparison. Measurements from both wmbusters showed that the slud es yield much higher N,O than the coals, in comparable combustion con %* Itions. Wet sludges emitted higher NIO than pre-dried slud es. Staged combustion proved effective for lowering the emissions of r$*O during the combustion of the pre-dried sludge. Increasing the freeboard temperature was shown to be the most effective way of reducing N,O. 95105362 Natlonal pollcls~ for achlsvln snsrgy thrift, envlronmental protsctlon, Improved quaPlty of Ilfs, and sustalnablllw Mackay, R.

For thrs studv. countries are cateaorised on the basis of their level of economic de&lopment (i.e. as b&g either industrialised or developing) and with respect to their indigenous energy resources (i.e. as being either energy rich or energy poor). A further factor to consider is the growing strength of the emerging regional tradin blocs in the world, and the moreeffective protectiomst measures that t%ese blocs have the potential to administer: a developing country is likely to benefit when it becomes part of such a trading bloc. Nevertheless not only re ionally, but also worldwide, governments are failing to address with su d lcient urgency the simultaneous but related problems and consequences. The issues that need to IX considered when trying to implement sustainable energy policies are discussed.
