Click on histogram for larger view
A histogram of cadmium  in all West Virginia coal beds shows a very narrow distribution of values with a mean of 0.096 ppm (± 0.131 ppm) on a whole coal basis. Isolated coal samples contained higher values up to 1.29 ppm, in a bench of the Winifrede coal.  Cadmium did not correlate with ash yield, total sulfur or pyritic sulfur, but correlated poorly with zinc (Zn) (r = +0.6250) and lead (Pb) (r = +0.5265) reflecting known relationships between these elements in the mineral sphalerite (ZnS) in coal.  Cadmium and lead are frequently present in minor amounts in solid solution in sphalerite.
