FIELD: environmental monitoring. SUBSTANCE: samples of soil are dried, screened to fraction below 1 mm, placed alternately in nonmagnetic cuvette, which is installed onto platform of magnetic susceptibility sensor. Measurement data are put down on the map of area being investigated and contour lines of magnetic susceptibility are drawn. Data exceeding background values are regarded as indicative of heavy metal polluted area zones. EFFECT: facilitated monitoring. 5 dwg
