Health aspects of coal fly ash
نویسندگان
چکیده
Employees of coal-fired power stations and people living nearby as well as those involved in the shipment and processing of coal fly ash can be exposed to coal fly ash (pulverised fuel ash or “PFA”). An extensive research program was carried out in order to map such exposure and its effects. Particle size distribution, chemical composition, quartz, radioactivity, emission factors and fugitive dust modelling were studied.

Distribution of trace elements in coal and coal fly ash and their recovery with mineral processing practices: A review
Today coal is among the most important energy sources. In order to meet the world's energy demands, low-calorie lignite with a high ash content is generally used in the large capacity coal-fired thermal power plants. As a result of coal firing, wastes such as fly ash, slag, and flue gas are also produced. Subsequently, toxic trace elements within coal are transferred to wastes such as slag, fl...

BACKGROUND U.S. military perception of nuclear warfare led to countless unethical nuclear experiments performed on unsuspecting individuals without their informed consent. As evidenced here, subsequent perception of weather warfare has led to exposing millions of unsuspecting individuals to toxic coal fly ash with no public disclosure, no informed consent, and no health warnings. METHODS Thre...
متن کاملPhysical and biological studies of coal and oil fly ash.
Studies were performed to compare the physical and chemical characteristics and the in vitro macrophage cytotoxicity of oil and coal fly ash. Sampling methodology was developed to collect size-fractionated particulate matter from the smokestack of either a coal-fired or an oil-fired power plant. Morphological studies demonstrated particle heterogeneity, although most coal fly ash particles appe...
متن کاملEnvironmental and health aspects of coal and biomass co-combustion ashes
Co-combustion is an important aspect of power generation from coal in the Netherlands and becomes increasingly important in the rest of Europe as well. To study these aspects several ashes have been sampled for many years under different firing conditions in test series, mostly at power plants. These ashes were analyzed and its properties assessed. Occupational health aspects discussed in this ...
