Despite the wide application of the electrical resistivity tomography (ERT) method to different environmental problems, it continually remains methodologically challenging in soil contamination near waste dumps of post-metal historical mining. The aims of our study were: (1) to validate ERT measurements for detecting soil contamination by trace elements in the vicinity of a waste dump containing post-processing spoil from Zn-Pb ore smelting, (2) to determine the extent of soil contamination, and (3) to analyze the mineralogical, physical, and chemical properties of the soils affected. ERT enabled us to study the variability of electrical properties of soils, to locate the area of contamination, and to evaluate its spatial diversity in both.

The total concentration of trace elements in soils was the highest down to a depth of 0.25 m and decreased in the order: Zn > Pb > Cu > Cd > Tl > As > Cr > Ni.

abstract = {Fractures commonly existing in rocks flow on their elastic properties and hence on velocity of seismic waves propagating in the rock mass. This relation allows to use seismic methods to determine the fracture density and the orientation of fracture sets.

Fractures commonly existing in rocks flow on their elastic properties and hence on velocity of seismic waves propagating in the rock mass. This relation allows to use seismic methods to determine the fracture density and the orientation of fracture sets. This paper presents results of the research which concern directional changes of dynamic elastic moduli in sedimentary and igneous rocks from south part of Poland. These moduli depend on density of the rock matrix as well as density and orientation of cracks and flow on seismic wave velocity.

The maximal values of moduli agree with maximal values of velocity and also with orientation of main crack sets or potential directions of weakening of rock mass.
