Determination of copper, iron, nickel, and sulphur by X-ray fluorescence in lichens from the Mackenzie Valley, Northwest Territories, and the Sudbury District, Ontario
X-ray fluorescence was adapted to the analysis of 22 terricolous lichen species from 14 sites in the Mackenzie Valley, Northwest Territories, and 7 species from the Sudbury District of Northern Ontario. X-ray fluorescence (XRF) proved to be faster and exhibited better sensitivity and reproducibility...
