Abstract

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.

天然水成分与生物体内脂质过氧化状态之间的关系

研究了五种天然水样的成分与基于天然磷脂的模型系统中脂质过氧化调节参数之间的关系，以及它们参与天然水毒性的情况。研究表明，天然水样中含有含 N 和 P 的化合物会抑制卵磷脂的自氧化作用和发光细菌的发光强度；对卵磷脂的自发聚集有显著影响，疏水化合物含量的增加会增加其颗粒ζ电位的负值。脂质过氧化调节系统的参数对天然水成分的敏感性很高，即使在天然水成分浓度很低的情况下也是如此，因此这些参数被认为是评估天然水对生物物体影响的有前途的指标。使用高斯方法对天然水样本的紫外线光谱进行数学处理，可作为分析其水化学成分的一种快速测试方法。生物测试方法证实了天然水成分对生物体膜状态和细胞内过程的影响。
