The major fossil fuels (oil, coal, gas) each use hundreds, if not thousands, of chemicals—often not disclosed—many of which are highly dangerous to human health. Attempting a comprehensive list of all the harmful chemicals used willingly by the oil, coal and gas industries would be far beyond the scope of .
Trace elements, such as, iron, manganese, zinc, copper, lead, nickel, chromium, cobalt, arsenic, cadmium, and mercury, can be found at higher concentrations compared to bottom ash and the parent coal. Fly ash can leach toxic constituents that can be anywhere from one hundred to one thousand times greater than the federal standard for drinking ...
Allowing coal ash to be spread on soil or stored in unlined pits and landfills will raise the risk that several toxic elements, including carcinogenic hexavalent chromium, could leach out of the coal ash and contaminate nearby water supplies across the U.S., according to .

High-uranium (U) coal is the dominant form of coal in Southwestern China. However, directly utilizing this resource can also harm the environment because this element is radioactive; it is, therefore, necessary to clean this kind of coal before burning. This research studied the geochemistry of toxic elements and their partitioning during the preparation of high-U coal in China.

----- ABSTRACT In this task, a list of specifically identified, poten- tially hazardous materials which may be associated with the air, water, and solid waste from a refinery, a coke plant, a Lurgi-high- Btu gas process, and the solvent refined coal process was compiled.
Mercury is a highly toxic element commonly found in coal and municipal waste. Wet scrubbers are only effective for removal of soluble mercury species, such as oxidized mercury, Hg 2+. Mercury vapor in its elemental form, Hg 0, is insoluble in the scrubber slurry and not removed.
Coal is the most abundant and widely spread fossil energy resource in the world (Benito, et al., 2001) [5]. Among the total power generated annually in India, about 70% is produced by thermal power plants. The majority of thermal power plants (about 84%) are running on coal with 70 billion tons of coal reserve, while the remaining 13% run on ...

Additionally, there is a significant cost associated with these technologies owing to the need for handling and processing contaminated waste water. For fly or coal ash, the other most common technique involves the use of either plasma heating the ash to temperatures in excess of 3,000° C., which reduces the heavy metals to their metallic state.
