Magnetic susceptibility mapping of roadside pollution

Abstract The aims of our study are to trace the distribution and concentration of contaminants in soils along roads and highways carrying appreciable traffic by using magnetic proxies. In addition, the concentration gradients and possible accumulation of pollutants in deeper soil layers are investigated. Magnetic susceptibility is used for pollution mapping in the field (Bartington bridge). The distribution of the susceptibility values represents polluted areas strongly influenced by traffic frequency, roadside topography, meteorological conditions (e.g., wind direction) and other factors. A magnetite-like phase was found to be responsible for the enhancement of the magnetic signal in the roadside soil.
