ANALYSIS OF PHYSICOCHEMICAL PARAMETERS AND TOTAL AMOUNTS OF MICROORGANISMS IN LAKE VLASINA

Abstract

The comprehensive examination of Like Vlasina microorganism levels and physico-chemical parameters during summer and winter aimed to assess water quality. The temperature ranged from 2 0C to 24 0C, pH from 6.20 to 8.40. Key indicators, such as ammonia 0.109-0.387 mg dm-3, nitrates 0.111-0.320 mg dm-3, and nitrites 0.002-0.025 mg dm-3, displayed distinct patterns. The count of mesophilic aerobic hemoorganotrophic microorganisms was lowest in winter 100 and peaked in summer 63500 no x 10-3 dm-3 Nitrogen gradients increased with depth. Emphasizing the need for continuous monitoring to prioritize lake protection and address pollution, ensuring its sustained revitalization.
