Аннотация: The aim of the present study has been to evaluate the extension of eventual influences on the surrounding vegetation of the emission from the iron-sintering plant in Sweden- in close proximity to the communities Koskullskulle, Malmberget and Gallivare. The yearly emission of sulphur dioxide and hydrogen fluoride has been around 2000 ton and 175 ton, respectively for the last years. The content of sulphur and fluorine in the needles of Scots pine from the sample plots has been analysed and correlated to the emission source. The needle drop of coniferous trees, well-known from air polluted areas, has been quantitatively recorded and correlated with the occurrence and physiological reactions in some lichen species from the emission source.
