Influence Of Hydrocarbon Pollution To Soil Conductivity

The laboratory and field measurements show. that small contents of hydrocarbon pollution<br>increase soil conductivity and greater contents decrease soil conductivity (Fig. 1.). We tested some hydrocarbon<br>materials and all had this ability.<br>On the basis of laboratory measurements was developed the field method for mapping the hydrocarbon<br>pollution, The method includes resistivity profiling (with GEONICS EM-31) measurement of streaming<br>potentials and atmogeochemical measurements (with ECOPROBE 3M). For different sources of hydrocabon<br>pollutions the method has some modifications.
