Abstract
The value of terricolous lichens as bioindicators of industrial metal fallout patterns is investigated; the widely-known inverse relationship between the metal content of lichens, as well as their associated soils, and the distance from the pollution source was found to be affected by microclimatic factors dependent upon soil surface topography and the local vegetation. Samples of lichen vegetation and their associated soils from Risby Warren, North Lincolnshire, were analysed for Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn. Enhanced concentrations of Fe and Mn in the lichen, soil and air samples were indicative of their emission from the nearby Scunthorpe steelworks. The highest concentrations of all metals analysed were found to be in the top layer (0-5 cm) of the soils.Keywords
