Abstract
Parmelia sulcata transplants were used in three different exposure systems, focused on three different influxes: free influx, horizontal influx and vertical influx. The total element deposition and the precipitation volumes were found to be positively correlated for Fe and Ni only. The element contents in lichen transplants and in total element deposition showed significant correlations for Ca, Fe and Mn in the free influx system and for Na, Ni and V in the horizontal influx system. No significant positive correlations were found for the vertical influx. The results indicate that, apart from response rates, the transplant positioning systems may have effects on element-specific net accumulation.
