Zusammenfassung:The relationship between the compositions of five natural water samples and the parameters of the lipid peroxidation regulation in a model system based on natural phospholipids, as well as their participation in the toxicity of natural water, have been studied. It has been shown that the presence of N- and P-containing compounds in natural water samples led to inhibition of lecithin autooxidation and luminescence intensity of luminous bacteria; it had a significant effect on spontaneous aggregation of lecithin and an increase in the content of hydrophobic compounds increased the negative value of the ζ potential of its particles. The high sensitivity of the parameters of the lipid peroxidation regulation system to the composition of natural water, even at low concentrations of its components, allows them to be considered as promising indicators for assessing the effect of natural water on biological objects. Mathematical processing of ultraviolet spectra of natural water samples using the Gauss method can be used as an express test for the analysis of its hydrochemical composition. The effect of natural water components on the state of membranes and intracellular processes of biological objects has been confirmed by biotesting methods.
