    Notes: Abstract During the months of July and August 1993 a lichen collection campaign was held in Portugal where about 250 samples were collected and analysed by thick target TIPIXE and INAA. Results for 44 different elements were obtained and a data base was built and subjected to Monte Carlo Aided Target Transform Factor Analysis (MCATTFA), a method developed at IRI (Delft). 10×10 km2 coast and 50×50 km2 far from coast sampling grids were used for collection. In this work we will present the results which were obtained based on a reduced data set of 36 elements measured by INAA. The results for 22 elements obtained by TTPIXE were published elsewhere. In this work we will also present the conclusions considering all the 44 elements determined by both techniques.

    Notes: An absolute quantitative analytical method without external standards has been developed for thick sample analysis by XRF and PIXE and has been applied to bronze and brass alloys. Comparisons between the results obtained and the chemical results were made and the detection limits for the determined elements were evaluated. In an Appendix a rapid calculation of the efficiency of the Ge(Hp) detector is presented.
