Int., Jun. 1995, 40, (491), 40-41. </p><p>Reports that Phase 1 of the European Union feasibility study on options for dealing with the Chernobyl sarcophagus has concluded that a second shel- ter is urgently needed and that stabilisation of the existing structure can only offer, at best, a short term solution. </p><p>95104094 Analysis of amlnes In petroleum Thomson, J. S. et al., J. High Resolut. Chromatogr., 1994, 17, (6), 415-426. Describes the development of an analytical method for differentiation of primary, secondary, and tertiary amines using exhaustive trifluoroacetyla- tion prior to GC/MS. Using the conditions described, most primary amines add two and secondary amines add one trifluoroacetyl group. In general, tertiary amines do not react. GC retention indexes and relative GC/MS ion current response factors for 102 trifluoroacetyl derivatives are reported. Provides examples of the application of the method to petroleum and coal liquid products. </p><p>95/04102 Avoiding excessive greenhouse effect by delayed emission of carbon dioxide from the fossil-fuel cycle Seifritz, W. Applied Energy, 1995, 51, (l), 39-49. In order to mitigate substantially the atmospheric CO, peak, responsible for the greenhouse effect, it is proposed to sequester carbon dioxide (CO,) from the fossil-fuel cycle and to store it in the form of CO, dry ice in huge, thermallv insulated. leakv reoositories lo delav the emission of CO. into the atmdsphere. 11 is estikated that a sphere of 60, dry ice, with a diaheter of 400 m and properly insulated by a 2 m thick layer of insulating material, will be sublimated completely in a time span of a few millenia. Since the recovery time of the atmosphere due lo an anthropogenic surplus of CO, inventory is much shorter than this time interval (about 200 years), the atmospheric CO, peak the scientific community is afraid of, will be delayed and damped drastically. </p><p>95104103 Bentonltes and coal waste transformation Lopez, R.

Reports on an investigation on the possibilities of cheap and ecological remediation of wastewaters, river sediment, and soil contaminated by lig- nite pyrolysis. The wastewaters could be treated biologically by the addi- tion of phosphate and inoculation with a nitrifying culture. </p><p>95104105 Blosurfactants production and possible uses in microbial enhanced oil recovery and oil pollution remediation: A revlew Banat, I. M. Bioresource Techno!., 1995, 51, (1). 1-12. Surfactants are widely used for various purposes in industry, but for many years were mainly chemically synthesized. It has only been in the past few decades that biological surface-active compounds (biosurfactants) have been described. Biosurfactants are gaining prominence and have already taken over a number of important industrial uses, due lo their advantages of biodegradability, production on renewable resources and functionality under~ extreme conditions; particularly those pertaining during tertiar) crude-oil recovery. Conflicting reports exist concerning their efficacy and the economics of both their prod&amp;on and application. At present,. their uses are mainly in the oil and petroleum industries, where they are </p><p>95104098 An assessment of air aualltv In Karachi.
