Comments
"TSCA Definition 2008: A complex combination of carbonaceous material including extremely high molecular weight hydrocarbons obtained as a solid material from the calcining of petroleum coke at temperatures in excess of 1000.degree.C (1832.degree.F). The hydrocarbons present in calcined coke have a very high carbon-to-hydrogen ratio." [ChemIDplus] Composed mainly of carbon (inert and of very low acute toxicity); [EPA ChAMP: Submission] An eye, upper respiratory tract, and mild skin irritant; Chronic inhalation exposure may cause pulmonary fibrosis; [Alcoa MSDS] See "Coke oven emissions."
