| Abstract: | Abstract Vanadium concentrations were determined by neutron activation analysis in samples of epiphytic lichens and tree foliage collected at sites along 10 transects in the vicinity of three oil-fired power plants in eastern Canada. The vanadium concentrations in plants decreased exponentially with increasing distance from the power plants. Substantially larger concentrations of vanadium occurred in lichen tissues than in tree foliage. Lichens clearly are more suitable for bio-monitoring environmental contamination with vanadium near oil-fired power plants. |
