04130 Determination of chemical species of selected trace elements in fly ash
15 Environment (pollution, health protection, safety) 95lO4129 Degradation of xenobiotic compounds in situ: Capabilities and limits Bouwer, E. et al., FEMS Microbial. Rev., 1994, 15, (Z), 307-317. Exploiting microorganisms for remediation of waste sites is a promising alternative to groundwater pumping and above ground treatment. The objective of in situ bioremedlation is to stimulate the growth of indigenous or”introduced microorganisms in regions of subsurfaci contaminati&, and thus to provide direct contact between microorganisms and the dissolved and sorbed contaminants for biotransformation. 95/04130 Determination of chemical species of selected trace elements In fly ash Polyak, K. et al., Talanta, 1994, 41, (7). 1151-1159. The paper describes how complex analysis methods were developed to determine the chemical composition of fly ash from coal-fired power plants and municipal waste incinerators. 95104131 Determination of tar and benzo(alpha)pyrene emissions from coal combustion and coking Orszulik, E. Chemik, 1994, 47, (1) 14-16. (in Polish) Presents a method for calculating fugitive emissions of tar and benzo(alpha)pyrene from coking and an installation is described for collection of the emissions and adsorption of the pollutants in a bed of sand. 95104132 Developing an industrial waste management facility design Becker, R. Plant Engng., Jan. 1995, 49, (l), 56-60. Discusses how traditional methods of waste disposal in the manufacturing industry are becoming unable to keep up with ever-changing regulations. Illustrates a typical waste management scheme, in which all the waste disposal methods involve an outside company. The trends seems to be a single waste management facility to serve the entire company. Describes one such scheme, which increases control over the initial stages of waste disposal. 95104133 Development and testing of new filter self-rescuers Bresser. G. et al.. Glue&auf 1994. 130. (11). 716. 718-719. (In German) Describes the breathing resistance of a new ‘gas mask (filter ‘self-rescuer 990) for coal mines, using artificial lungs and man tests. The advantages of the new gas masks are low breathing resistance, low temperature of breathed air, and easy handling and wearing, and safety.

The book contains excerpts from panel dtscussions dealing with controlling and abolishing nuclear weapons. 95104135 The distribution effects of economic instruments for envlronmental policy OECD, 2 Rue Andre Pascal, 75775 Paris Ceder 16, France, 1994,159 pp. The report provides a framework for estimating the distributive effects of economic htstruments used in environmental-policy (emission charges, eco-taxes, and tradeable permits). Dust measurements in lignite-fired power plants 95104136 for an epidemlological study Thuermer, H. ef al., Staub-Reinhalt. Luft., 1994, 54, (5) 193-197. (In German) Presents gravimetric dust measurements at two lignite power station dust and ash disposal systems. The average levels, frequency distributions, relationships between particle fractions, and levels of selected chemical elements m airborne dusts revealed a log normal distribution of dust fractions and toxic element contents below the permissible limits. 95104137 The eco-management and audit scheme: A practical guide Hillary, R.

Effect of fly-ash application on yield and nutrient 95104138 composition of rice, wheat and on pH and available nutrient status of soils Sikka, R. and Kansa!, B. D. Bioresource Technoi., 1995,51, (2), 199-203. A greenhouse experiment was conducted to evaluate the effect of fly-ash application on dry-matter yield and nutrient composition of 60 day-old rice and wheat plants and on pH and available nutrient status of soils: Fly-ash was collected from an old deposit of a thermal power plant and was mixed with seven soils. Moderate rates of fly-ash application had a beneficial effect on the dry-matter yield of paddy, but a higher level had a significant depressing effect. Addition of fly ash resulted in a significant increase in the contents of N, S, Ca, Na and Fe and a significant decrease in P and Zn contents of rice

95104139 Effect of sulfur In reducing PCDD/PCDF formation Raehunathan. K. and Gullett. B. K. Proc. 13th Int. Incinceration Conf Therm. Treat. Radioact. Hazard. Chem. Mixed Munitions Pharm. Wastes, Univ. of Calij Irvine, USA, 1994, 225-230. Research has been conducted to determine whether the co-firing of coal with municipal solid waste (MSW) will decrease the downstream formation of chlorinated organic compounds, particularly polychlorinated dibenzo-p-dioxins and furans (PCDDs and PCDFs). Tests were conducted with a MSW fly ash in EPA’s pilot-scale innovative Furnace Reactor (IFR) and a bench-scale Short Time Differential Reactor. Bench-scale tests also confirmed the inhibitory effects of S. Depletion of Cl by SO, through a gas-phase reaction appears to be a significant inhibition mechanism, in addition to previously reported SO, deactivation of Cu catalysts.

One result frequently reported in the literature is that certain metals retard the rate of cement hydration. An empirical study focused on the effect of accelerators on the stabilization of K061 waste is discussed.
95104141 The effects of acidity on carbon fluxes from ombrotrophic peat Sanger, L. J. et al., Chem. Ecol., 1994, 8, (4), 249-264. Replicate intact peat/vegetation monoliths were collected along a pollution gradient in the UK, and subjected over one year in 1200 mm of simulated rainfall of the same chemical composition as they received in the field. Drainage water was analyzed periodically for DOC and pH. The chemical characteristics of the peats as initially sampled from the field were also determined. Results suggest that acidic precipitation has induced chemical chanees in ombrotroohic neats. lower their OH and base status. when due accoint is taken of calciu’m deposition or a;y mineral content.’
95104142 Effects of PAH lsomeriratlons on mutagenicity of combustion products Howard, J. B. et al., Combustion & Flame, May 1995, 101, (3), 262-270. Most of the mutagenicity of mixtures of polycyciic aromatic hydrocarbons (PAH) mixtures found in combustion exhaust gases is contributed by a relatively small number of the many PAH present. Since PAH mutagenicity is structure and hence isomer sensitive, changes in the distribution of isomers can change the mutagenicity of the mixture. Whether isomerization reactions in combustion play a significant role in determining the distributions of PAH isomers and the mutagenicity of product mixtures is assessed here for pairs of isomers.
