Thermal effluent from a large coal-fired electric generating facility located on Mt. Hope Bay in the Narragansett Bay (Rhode Island, U.S.A.) has been implicated in a large decline in fish populations in this region. Detailed information on the spatial and temporal properties of this thermal input (approximately 5 million m day 1 of thermal effluent 7 C above ambient) is, however, lacking. In th...

The relationship between glucose-induced insulin secretion and metabolism of inositol phospholipid was investigated by means of an islet perifusion method and direct measuring of inositol phosphates after sonicating the islets. The results showed that the time course of inositol phospholipid breakdown is coincident with the first phase of glucose-induced insulin secretion. Analysis of the efflu...

The effect of the two parameters is reviewed. Variability with time is discussed in relation to stability and other atmospheric conditions. The magnitude of ground level concentrations from elevated release is discussed as an interaction between rate of emission release, physical height of stack, and thermal conditions. The point is made that plant effluent rates have increased in proportion to...

Dye tracer technique is well established and of wide application for assessment of outfalls and for delineation of near field and far field extensions. Common goals of a tracer study include the measurement of the dilution factor, estimation of the dispersion coefficients, measurement of the effluent discharge and calibration of a contaminant transport model. This paper presents a brief review ...

Magnesium oxide suitable for the use in basic refractories was prepared from dolomite (CaMg(CO3)2) by hydrochloric acid leaching, precipitation with CO2 and thermal hydrolysis. Leaching of the dolomite ore in aqueous hydrochloric acid solution was investigated with respect to the effects of time on dissolution of the dolomite sample. The dependence of the observed dissolution rate on pH was est...

Wastewater treatment plant effluent can increase stream water temperature from near freezing to 5°C–12°C in winter months. Recent research the South Platte River Basin Colorado showed that this warming alters reproductive timing of some fishes. However, spatial extent and magnitude are unknown. Thus, we created models both upstream downstream inputs for two urban tributaries River, Big Thompson...

Persistent Organic Pollutants (POPs) are toxic, persistent, bioaccumulative and prone to long-range transport. In the environmental sectors, solids including soil and sediment are recognized as the ultimate ‘sink’ for accumulating POPs. In order to combat the threat posed by POPs to human health and the environment, research and development of technologies for removal of POPs from solids have g...

Pyrolysis of chlorinated phenolics and thiolignin was investigated to elucidate the principle step occurring during combustion of organic material in bleach plant effluent. Chlorinated phenolics found in bleach plant effluent. such as chlorophenols, chloroguaiacols, chlorovanillins and chlorosyringaldehydes, were completely decomposed at 700 to 900°C with alkali and oxygen. Organically bound ch...
