Effect of the combined action of heavy metals and phenols on aquatic organisms
The most toxic in the wastewaters of petroleum refining and pulp and paper enterprises are phenol compounds, and in nonferrous, mining, and chemical industries, heavy metals, of which the most dangerous are mercury, nickel, and cadmium. The purpose of this article is to determine the main characteristics of the combined effect of heavy metals and phenols under conditions of an acute experiment. An analysis showed that the method of quenching the luminescence of luminescent bacteria most completely meets the imposed requirements. The use of microorganisms as test objects for determining the toxicity of substances is, according to the authors, especially promising for biological testing. It was necessary to prove experimentally that a change in luminescence adequately reflects the disturbance of physiological and biochemical processes in the cell.
