Abstract

Transplants of the lichen Parmelia sulcata were suspended in nylonbags in a region within a rectangle of 15 km wide and 25 km long on a grid2.5 km × 2.5 km, centred in a oil powered station. In each of the 47places, two sets of four transplants each were hung in a system that rotatesaccording to the wind direction. One set was always facing the wind and theother downwind. Every three months for a 9-month period one transplant fromeach set was collected. The transplants were analysed by instrumental neutronactivation analysis (INAA) and proton induced X-ray emission (PIXE). The transplantbehavior according to the different exposure to the wind is investigated,and some emission sources are identified.
