“…In spite of the heterogeneity noted by White et al (1989), the bulk cleat infill does not apparently differ significantly in composition to the early diagenetic pyrite, suggesting a diagenetic origin for both. In some US coals it has been noted that the trace element composition of pyrite varies significantly both between samples and also within sample grains (Hower et al, 1997(Hower et al, , 2007Ruppert et al, 2005;Goldhaber et al, 2002;Diehl et al, 2004 ), which does not conflict with the conclusions of White et al (1989).…”

“…This mineral contains nearly all the Hg, As, Se, Tl and Pb and most of the Mo, Ni, Cd and Sb. Sulphides in coal, and pyrite in particular, have long been recognised as an important location for many of the chalcophile trace elements (see for example Finkelman, 1982;Hower, 1997;Gayer et al, 1999). In general, coals high in sulphur typically contain more Hg, which is usually in pyrite (Yudovich and Ketris, 2005).…”

The Parkgate coal of Langsettian age in the Yorkshire-Nottinghamshire coalfield is typical of many coals in the UK in that it has a high sulphur (S) content. Detailed information on the distribution of the forms of S, both laterally and vertically through the seam, was known from previous investigations. In the present work, 38 interval samples from five measured sections of the coal were comprehensively analysed for major, minor and trace elements and the significance of relationships established using both raw and centered logtransformed data.The major elements are used to quantify the variations in the inorganic and organic coal components and determine the trace element associations. Pyrite contains nearly all of the Hg, As, Se, Tl and Pb and is also the major source of the Mo, Ni, Cd and Sb. The clays contain the following elements in decreasing order of association: Rb, Cs, Li, Ga, U, Cr, V, Sc, Y, Bi, Cu, Nb, Sn, Te and Th. Nearly all of the Rb is present in the clay fraction, whereas for elements such as V, Cu and U, a significant amount is thought to be present in the organic matter, based on the K vs trace element regression equations. Only Ge, and possibly Be, would appear to have a dominant organic source. The trace element concentrations are 2 calculated for pyrite, the clay fraction and organic matter. For pyrite it is noted that concentrations agree with published data from the Yorkshire-Nottinghamshire coalfield and also that Tl concentrations (median of 0.33 ppm) in the pyrite are greater than either Hg or Cd. Unlike these elements, Tl has attracted less attention and possibly more information is needed on its anthropogenic distribution and impacts on man and the environment. A seawater source is thought to be responsible for the high concentrations of S, Cl and the nondetrital trace elements in the Parkgate coal. Indicative of the seawater control is the Th/U ratio, which expresses the detrital to non-detrital element contributions. Using other elements, similar ratios can be calculated, which in combination offer greater interpretative value.

“…Whole-channel As (ash basis) is higher at the two western sites, but not significantly higher than at the eastern sites. The wholechannel As is, in certain cases, among the highest found in Eastern Kentucky, comparable to high values in the Fire Clay coal bed (Hower et al, 1997).…”

“…Note that some samples with >1000 ppm As have < 100 ppm Pb (both on ash basis). This is not surprising since, although both elements can have associations with sulfide minerals, they are not necessarily distributed uniformly in sulfides present in coal (Ruppert et al, 1995;Hower et al, 1997). Lead, as will be noted below, may have its primary form in a selenide, not a sulfide (Hower and Robertson, 2003).…”

“…Coal shipped to and from the Lambert's Point Docks originates from mines in Alabama, Indiana, Illinois, Kentucky, Tennessee, Ohio, Pennsylvania, Virginia, (Henderson et al 1985;Hower et al 1997). These mean values are between an order of magnitude to as much as ∼45 times greater than upper continental crust As concentrations (1.5-2.0 mg/kg; Taylor and McLennan 1985;Wedepohl 1995).…”

Soil samples were collected from Norfolk, Virginia in order to examine the extent of particulate coal, and associated arsenic (As) deposition to local soils. The particulate coal originates from the adjacent coal shipping terminal at the Lambert's Point Docks, which is the largest marine coal shipping terminal in the Northern Hemisphere. Particulate coal was separated from soil samples using heavy liquid (i.e., sodium polytungstate) extraction. Sand-sized coal separates isolated from the soil samples were subsequently digested using concentrated nitric and sulfuric acid, and analyzed for As by high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). Selected total soil digests were also analyzed for As by HR-ICP-MS. Results indicate particulate coal ranges from less than 1% up to ∼20%, by weight, of the soil samples analyzed. Arsenic concentrations in sand-sized particulate coal extracted from these sediments range from undetectable levels (i.e., <3 ng/kg) up to 17.4 mg/kg, whereas total As concentrations in the soils range from 3 to 30.5 mg/kg. The data indicate that particulate coal originating at the Lambert's Point Docks is an additional source of As to local soils, especially sites proximal to the shipping terminal. Although the particulate coal itself likely poses only minor health hazards (if any), the environmental consequences of As transported with the particulate coal is not known.
