| Abstract: | The goal of the study was the geostatistical evaluation of quantitative magnetic measures, which can be used for effective
delineation of the extent of the area polluted with heavy metals. Several parameters of magnetic susceptibility, measured
in the soil profile, were proposed as magnetic indicators of soil pollution and analyzed in detail. The following parameters
were calculated: maximum magnetic susceptibility, magnetic susceptibility at the depth of 3 cm and 5 cm, and the area under
the curve of magnetic susceptibility. Measurements were performed at two forested study areas, located in Upper Silesian Industrial
Area (Poland). Analyses were performed using geostatistical methods, and the results were verified using dense chemical measurements.
The results showed that the area under curve of magnetic susceptibility was the most effective magnetic indicator of soil
contamination with heavy metals. It was possible to detect the entire polluted area, and only about 16% of the study area
was assumed to be contaminated while being unpolluted. The results obtained with maximum magnetic susceptibility and magnetic
susceptibility at the depth of 3 cm and 5 cm were less effective in comparison with the area under curve of magnetic susceptibility. |
