Abstract
The operations of the Dave Johnston coal-fired powerplant near Glenrock, Wyoming [USA] have had a measurable effect on trace-element concentrations in P. chlorochroa Tuck., which is common to the area. Concentrations of 35 elements were measured in samples collected along upwind and downwind transects. Of these elements, concentrations of Ca, F, Li, Se, Sr and U, as well as ash yields, decreased with distance from the powerplant. Compared to background levels established for this lichen from the Powder River Basin, only the Se values near the powerplant are considered unusually high.This publication has 1 reference indexed in Scilit:
