Abstract
The vanadium content of the lichen Hypogymnia physodes was determined in the vicinity of a power plant using heavy oil as fuel. For the chemical analysis a DC plasma emission spectrometer was used. Air dried samplesof the lichen contained between 1–4 and 57 parts per million (ppm) of vanadium. The highest concentrations were found in specimens collected less than 1 km from the power plant. Lichens collected 50 km from the plant contained less than 2 ppm of vanadium.
