Recent work has refined mode-of-occurrence data for Ni, Cr, and As, as compared to previous summaries. For Cr, dominant modes of occurrence include the clay mineral iliite, an amorphous CrO(OH) phase, and Cr-bearing spinels. Nickel is present in Fe-sulfides (pyrite and marcasite) and is also organically bound. Arsenic-bearing pyrite may be the dominant host of As in bituminous coals.Concentration data for the 13 HAPs, obtained primarily by quantitative microanalysis techniques, are compiled for mineral and organic portions of coal. HAPs element concentrations are greatest in Fe-sulfides, and include maxima of 2,300 ppm (Co), 4,500ppm (Ni), 4.9wt.% (As), 2,000ppm (Se), 171 ppm (Hg), and 5,500ppm (Pb). Trace-element microanalysis is a significant refinement over bulk methods, and shows that there is considerable trace-element variation on a fine scale for a given coal, and from one coal to another.", "description": "25 p.", "publisher": { "@type": "Organization", "name": "Taylor & Francis" }, "author": [ { "@type": "Person", "name": "Kolker, Allan akolker@usgs.gov", "givenName": "Allan", "familyName": "Kolker", "email": "akolker@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-5768-4533", "url": "https://orcid.org/0000-0002-5768-4533" }, "affiliation": [ { "@type": "Organization", "name": "Eastern Energy Resources Science Center", "url": "https://www.usgs.gov/centers/geology-energy-and-minerals-science-center" } ] }, { "@type": "Person", "name": "Finkelman, Robert B.", "givenName": "Robert B.", "familyName": "Finkelman", "affiliation": [ { "@type": "Organization", "name": "University of California - Berkeley" } ] } ], "funder": [ { "@type": "Organization", "name": "Eastern Energy Resources Science Center", "url": "https://www.usgs.gov/centers/geology-energy-and-minerals-science-center" } ] }, "OpenAlex": { "abstract_inverted_index": { "Mode-of-occurrence": [ 0 ], "data": [ 1, 29, 84 ], "are": [ 2, 95, 107 ], "summarized": [ 3 ], "for": [ 4, 30, 85, 97, 151 ], "13": [ 5, 87 ], "potentially": [ 6 ], "hazardous": [ 7 ], "elements": [ 8 ], "(Be,": [ 9 ], "Cr,": [ 10, 32, 41 ], "Mn,": [ 11 ], "Co,": [ 12 ], "Ni,": [ 13, 31 ], "As,": [ 14, 34 ], "Se,": [ 15 ], "Cd,": [ 16 ], "Sb,": [ 17 ], "Hg,": [ 18 ], "Pb,": [ 19 ], "Th,": [ 20 ], "U)": [ 21 ], "in": [ 22, 61, 80, 109 ], "coal.": [ 23, 103 ], "Recent": [ 24 ], "work": [ 25 ], "has": [ 26 ], "refined": [ 27 ], "mode-of-occurrence": [ 28 ], "and": [ 33, 55, 64, 66, 99, 111, 127, 139, 155 ], "as": [ 35 ], "compared": [ 36 ], "to": [ 37, 159 ], "previous": [ 38 ], "summaries.": [ 39 ], "For": [ 40 ], "dominant": [ 42, 76 ], "modes": [ 43 ], "of": [ 44, 78, 102, 114 ], "occurrence": [ 45 ], "include": [ 46, 112 ], "the": [ 47, 75, 86 ], "clay": [ 48 ], "mineral": [ 49, 98 ], "iliite,": [ 50 ], "an": [ 51 ], "amorphous": [ 52 ], "CrO(OH)": [ 53 ], "phase,": [ 54 ], "Cr-bearing": [ 56 ], "spinels.": [ 57 ], "Nickel": [ 58 ], "is": [ 59, 67, 132, 143 ], "present": [ 60 ], "Fe-sulfides": [ 62 ], "(pyrite": [ 63 ], "marcasite)": [ 65 ], "also": [ 68 ], "organically": [ 69 ], "bound.": [ 70 ], "Arsenic-bearing": [ 71 ], "pyrite": [ 72 ], "may": [ 73 ], "be": [ 74 ], "host": [ 77 ], "As": [ 79 ], "bituminous": [ 81 ], "coals.": [ 82 ], "Concentration": [ 83 ], "HAPs,": [ 88 ], "obtained": [ 89 ], "primarily": [ 90 ], "by": [ 91 ], "quantitative": [ 92 ], "microanalysis": [ 93, 131 ], "techniques,": [ 94 ], "compiled": [ 96 ], "organic": [ 100 ], "portions": [ 101 ], "HAPs": [ 104 ], "element": [ 105 ], "concentrations": [ 106 ], "greatest": [ 108 ], "Fe-sulfides,": [ 110 ], "maxima": [ 113 ], "2,300": [ 115 ], "ppm": [ 116, 125 ], "(Co),": [ 117 ], "4,500ppm": [ 118 ], "(Ni),": [ 119 ], "4.9wt.%": [ 120 ], "(As),": [ 121 ], "2,000ppm": [ 122 ], "(Se),": [ 123 ], "171": [ 124 ], "(Hg),": [ 126 ], "5,500ppm": [ 128 ], "(Pb).": [ 129 ], "Trace-element": [ 130 ], "a": [ 133, 148, 152 ], "significant": [ 134 ], "refinement": [ 135 ], "over": [ 136 ], "bulk": [ 137 ], "methods,": [ 138 ], "shows": [ 140 ], "that": [ 141 ], "there": [ 142 ], "considerable": [ 144 ], "trace-element": [ 145 ], "variation": [ 146 ], "on": [ 147 ], "fine": [ 149 ], "scale": [ 150 ], "given": [ 153 ], "coal,": [ 154 ], "from": [ 156 ], "one": [ 157 ], "coal": [ 158 ], "another.": [ 160 ] }, "apc_list": null, "apc_paid": null, "authorships": [ { "author_position": "first", "author": { "id": "https://openalex.org/A5005580240", "display_name": "Allan Kolker", "orcid": "https://orcid.org/0000-0002-5768-4533" }, "institutions": [ { "id": "https://openalex.org/I1286329397", "display_name": "United States Geological Survey", "ror": "https://ror.org/035a68863", "country_code": "US", "type": "government", "lineage": [ "https://openalex.org/I1286329397", "https://openalex.org/I1335927249" ] } ], "countries": [ "US" ], "is_corresponding": false, "raw_author_name": "ALLAN KOLKER", "raw_affiliation_strings": [ "U.S. Geological Survey , 956 National Center, Reston, VA, 20192" ], "affiliations": [ { "raw_affiliation_string": "U.S. Geological Survey , 956 National Center, Reston, VA, 20192", "institution_ids": [ "https://openalex.org/I1286329397" ] } ] }, { "author_position": "last", "author": { "id": "https://openalex.org/A5078449933", "display_name": "Robert B.
