Abstract: The research covered in the suggested article is meant for ecological monitoring in the broad sense. The express-method of water solution quality level estimation and the technique of fast response to the quality level of industrial, agricultural and domestic wastewaters along with food products are proposed. The novelty of the proposed technique roots in the implementation of suggested methods and means of electric parameter measurement aimed at the quality index controlling of nonelectric qualimetry objects. Relevant research includes the exploration of water-solutions as well as different-level purification of industrial and domestic spillage waters, colloid solutions (cream, milk with the known contaminants), mixtures of superficially active substances and chlorine-containing substances.


Keywords: Threshold concentrations (ThC’s), Wastewater, Ecological water monitoring, Impedance method, Conductometry method
