Gent air samplers were used for air particulate matter sampling in Sado estuary area, separating fine and coarse fractions.
Three sampling sites were chosen (Palmela, Faralhão and Tróia), inside a 15 km × 25 km area at Setúba region, 50 km south
of Lisbon, Portugal. Transplants of Parmelia sulcata Taylor were suspended in nylon bags within the same area following a 2.5 km × 2.5 km grid, during the same period as the
aerosol collection. Both lichen transplants and filters were analysed by k0-INAA. This work compares MCTTFA results given by the two air pollution monitoring procedures. The main differences concern
a physiological factor in biomonitors and a better definition of traffic and re-suspension by aerosols.
