Abstract
This study presents hydrochemical assessments conducted in the vicinity of a trout farm in Lake Kholmovskoye during the summer of 2022 and winter of 2023. Parameters including pH, mineralization, dissolved oxygen, and nutrient levels were analyzed. The compliance of these parameters with regulatory standards for water quality in fisheries was evaluated. Based on its chemical composition, Lake Kholmovskoye is classified as a low-mineralized, hydrocarbonate-type lake (131 mg/L) with a slightly alkaline pH range of 7.9–8.3. Observations indicated that concentrations of phosphorus, nitrogen, and silicon salts in both summer and winter did not exceed permissible limits for fisheries. Dissolved oxygen levels were within acceptable ranges for aquatic life during both periods of the study.
期刊介绍：
Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
