“…Even when present at only parts per million levels in coal, hazardous elements can result in tons of pollutants discharged into the environment (von Storch et al, 2003). Previous studies have indicated the modes of occurrence, contents and distributions of Cd, Cr, and Pb varied substantially among provinces, sources, and even the coal of the same seam (Bai, 2003;Song et al, 2007;Li et al, 2006;Lu et al, 1995;Zhou et al, 2010).…”

“…In this paper, field test content data of Cd (616 samples), Cr (956 samples), and Pb (831 samples) for different Chinese raw coal are summarized from available published literature (Bai, 2003;Dai et al, 2006;Zhou et al, 2010). First, the average content of each of these elements in coal as produced on a provincial-level are determined by using a bootstrap simulation (Tian et al, 2011).…”

The quantitative measurements of uncertainties regarding the contents of hazardous trace elements (HTEs) serve as a basis for better assessment of the geochemistry and mineralogical characteristics of coals and their environmental impacts. In this paper, by using bootstrap simulation methodology, a quantitative procedure was demonstrated to characterize the variability and uncertainty of HTE (Cd, Cr, and Pb) contents in Chinese coals, which were specified by 27 different provinces and mining areas. Original data samples for Cd, Cr, and Pb contents in Chinese coals were compiled and summarized from the results reported in published literature. Sampling distributions for uncertainties in statistics such as the mean, median, and confidence interval were calculated. The national average contents were estimated at approximately 0.61 g/g for Cd, 30.37 g/g for Cr, and 23.04 g/g for Pb. The ranges of uncertainties for bootstrap samples of national HTE contents were nearly symmetrical, and the ranges of the 95% confidence interval for the arithmetic mean were relatively small, with relative uncertainties of Ϫ16.39% to ϩ21.31% for Cd, Ϫ10.11% to ϩ11.72% for Cr, and Ϫ8.55% to ϩ8.64% for Pb.

“…Zinc in most coal is generally associated with sulphides such as sphalerite and pyrite (Finkelman 1995;Hower et al 2008). There are some studies which reported that Zn is association with aluminosilicate (Zhou et al 2010). Zinc has very strong positive correlation with Ni, which indicates that there may be possible occurrence with clay minerals along with organic complex.…”

The mineralogy and trace element contents in coals from the West Bokaro coalfield, which is the one of the biggest Gondwana coalfields of India, were studied to delineate enrichment of trace elements and their modes of occurrence. Elemental concentrations with reference to their crustal abundances indicated that coals are relatively enriched in As (4.4-15.5 mg/kg), Cd (0.3-3.0 mg/kg), Cu (28.0-68.1 mg/kg) and V (46.6-178.0 mg/kg); depleted in Co (10.8-28.4 mg/ kg), Mn (7.6-483.4 mg/kg), Ni (13.0-31.6 mg/kg), Cr (14.2-85.5 mg/kg) and Zn (5.25-70.4 mg/kg). The concentration of As, Cd, Co, Cu and V were higher than the average values of world and Indian coals. Mineralogical study carried out by X-ray diffraction shows that quartz and kaolinite occur as dominant mineral phases in this coal. Fourier transform infrared spectroscopy pattern suggests organic structures primarily containing aromatic nuclei, aliphatic side chain and some oxygen containing groups. The modes of occurrence of trace elements present in these coals have been determined through statistical approach. Both Cu and Cr are more closely associated with mineral matter, whereas Co is dominantly present with its organic form. The concentrations of Cd, Mn, Ni, Zn, As and V have apparently occur in both organic and inorganic constituents. This study would be helpful to assess the potential environmental impacts during mining and combustion of this coal.
