Mutagenicity in emissions from coal- and oil-fired boilers.
The mutagenicity of emission samples from three oil-fired and four coal-fired boilers have been compared by using the Salmonella/microsome assay. Very little or no mutagenic activity was observed in samples from five of these boilers. The sample from one oil-fired boiler showed mutagenic activity of about 500 revertants/MJ, and the sample from a coal-fired fluidized bed combustor had an activit...
متن کاملControl of mercury emissions from coal-fired electric utility boilers.
Introduction During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg to ionic mercury (Hg) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto t...
متن کاملVanadium poisoning from gas turbines.
Vanadium pentoxide poisoning has been described in men working in plants processing vanadium ore by Symanski (1939) and Sjoberg (1950), and twice (Wyers, 1946; Williams, 1952) in men exposed to the soot of fuel oil burned in boilers. It does not, however, appear to have been described before in men who work on gas turbines. Since these may become much more common in the future as sources of pow...
متن کاملActivated carbons from oil-fired fly ashes
Introduction. The aim of this investigation is to prepare activated carbons with good sorbent characteristics from oil-fired fly ash, looking for suitable activation processes to produce surface sites with high reactivity on the carbonaceous matrices [1-4]. In particular, the nitrogen surface sites, formed by gaseous ammonia reaction at 800°C, could greatly increase the adsorption of gaseous sp...
متن کاملDirect effect of vanadium on citrate uptake by rat renal brush border membrane vesicles (BBMV).
Vanadium pentoxide is used as a catalyst and a ferrovanadium alloy ingredient in automotive steels and in jet engines and airframes. In addition, vanadium is found in fuel oils. Thus, occupational exposures to vanadium pentoxide and trioxide may occur during the cleaning of oil-fired ship boilers, and from oil-fired power station boilers. Occupational exposure to vanadium pentoxide induces gree...
