Description:   The effects of time on lichen sensitivity to sulphur dioxide were studied by measurement of potassium ion efflux and carbon-14 fixation in Cladina rangiferina after sulphur dioxide exposure.  Metal and sulphur levels in lichens from selected sites in eastern Canada were determined by X-ray fluorescence.  Elemental content in the lichens was found to correspond with the levels of contamination in the test sites.
