Abstract
A study at the Ferrol-Fene area by means of epiphytic lichens as biological monitoring of air pollution is carried up. There were selected 24 sampling points at Ferrol town and another 5 at Fene. The used methods were the Index of Atmospheric Purity (TAP.) of Leblanc & De Sloover (1970), the qualitative scale of Hawksworth & Rose (1970) and the qualitative scale modified for Galicia of Carballal & García Molares (1987-88). Three zones of isopollution were delimited and mapped taking in account the I.A.P. and the qualitative scale modified for Galicia.
