Abstract
Multi-element analysis of environmental samples have been carried out by charged-particle activation using the Melbourne University Cyclotron. The air particulate matter collected in polystyerine filters around Brisbane have been found to contain S, Ca, Ti, Cr, Fe, Ni, Cu, Zn, Sc., Sr, Y, Zr, Nb, Ru, Pt and Hg ranging in concentration from 0.01 μg to 1.02 μg/m3 A comparison of the elemental concentration between the ashed roots of diseased and healthy eucalyptus trees from the Brisbane Ranges in Victoria using proton activation has indicated that the diseased tree contents of iron and titanium are only 30% and 59% respectively of that contained in healthy trees.
