A methodology of integration of magnetometric and geochemical soil contamination measurements

摘要: Abstract There is still a high interest in the improvement of soil magnetometry procedures that could increase its accuracy. As it was often discussed literature, depth penetration magnetometric probe used to measure magnetic susceptibility on surface (e.g. MS2D) can be insufficient acquire signal pollutants accumulated deeper-located horizons. The goal this study propose practical methods integration and vertical measurements susceptibility, thus eliminate, or at least, minimize number geochemical measurements. It assumed these must cost- time-effective, easy implement, because vital importance for fast screening method. Results obtained paper clearly showed method should depend mainly thickness organic horizon layer where enhancement observed. soon as an falls interval between 15% 30% effective range Bartington MS2D magnetometer assessment potentially polluted area becomes problematic. In such situation, extent determined using values measured with device were integrated width started observed profile. Values Pearson's correlation coefficient Pollution Load Index ranged 0.63 0.77. case large removal problematic, sufficient use cokriging order integrate parameters However, if sample points high, assessed ordinary kriging surface. Validation results estimated concentrations Co, Ni, Cd, Pb significant, equaled 0.77, 0.76, 0.65, 0.74, respectively.
