Abstract

The effects of joint action of SO2 and HF on three Eucalyptus species were studied by exposing them to combinations of <13, 122 or 271 μg m−3 of SO2 and 0·03, 0·39 or 1·05 μg m−3 of HF in open top chambers for 120 days. HF and SO2 reduced the area and weight of immature leaves in all three species, but there were few interactive effects on immature leaves. The response of mature leaves to exposure differed among the species, with the greatest effects on E. calophylla and least effects on E. marginata. The interaction of HF + SO2 had no effect on leaf S concentrations in any of the species, but it reduced leaf F concentrations in E. calophylla and E. gomphocephala. HF increased leaf injury in E. calophylla and E. gomphocephala when simultaneously exposed to 271 μg m−3 of SO2, but had no effect at 122 μg m−3, or on E. marginata. The addition of 271 μg m−3 of SO2 increased leaf injury when E. gomphocephala was exposed to 0·39 μg m−3 of HF and when E. calophylla was exposed to 1·05 μg m−3 of HF, despite reducing the leaf F concentrations. In some cases the interaction of the pollutants may increase susceptibility to visible injury.
