Sequential extraction of metal forms in the soil near a roadway in southern Poland

Abstract

The sequential extraction of different metal forms (exchangeable, carbonate, Mn oxides, Mn–Fe oxides, organic, residual) in soil for five locations in Istebna during 1992–93 was performed. Two sites were localized in a ‘clean’ region (national park) and the remaining sites were near a road. Istebna is a small, non-industrial mountain town and the local emission source is the roadway, where the average traffic intensity is about 74 cars per hour. One- and three-way analyses of variance (ANOVA and MANOVA, respectively), were performed to investigate influence of location (roads, ‘clean}’) and the form of metal. Individual metal forms in the soil differ essentially (p < 0.000001). The location was statistically significant at the level p= 0.059, whereas the interaction effect between the location and the type of form was significant at the level P= 0.09.
