Polycyclic Aromatic Hydrocarbons
Produced from burning coal, fly ash is a mixture of alumina, silica, carbon, and metal oxides; The alumina may be recovered by calsintering. Used as an additive in oil well casings and an absorbent in oil spills and wastewater treatments; [Hawley]
See the Process, "Cleaning Furnaces and Flues." Metal exposures include arsenic, cesium, selenium, thallium, and vanadium. Workers cleaning furnaces and flues may also be exposed to asbestos, coal tars, silica, and soots.
