Trace Elements in West Virginia Coals
geographic distribution of Mercury (Hg) in West Virginia coals show very
low abundances (<0.4 ppm) for almost all coals. Mercury contents up
to 1.0 ppm occurred in a few coals with one thin, very high sulfur coal
containing 9.3 ppm whole coal Hg. Unusually high mercury contents
occurred in generally unminable coals in Mineral County, and moderate Hg
was noted in similar age coals in Preston and Monongalia counties (see
cautionary note page). These coals were very high in total sulfur,
and mercury content correlated somewhat (r = +0.6184) with total
sulfur but poorly (r = +0.4060) with pyritic sulfur.
