New method for testing contaminated soil——electrical resistivity method

Because there was no special apparatus to be used to test contaminated soils in China,a kind of instrument that could examine contaminated soil was manufactured according to the resistance method.And through tests on simulated samples contaminated with Fe and Al,the availability and veracity of the apparatus was proved.Furthermore,it was shown by in-situ examination that the electrical resistivity could be dtermined conveniently,easily and nondestructively.
