Chlorophyll and nutrients content in the coastal waters of lake Baikal

The investigation revealed some regularity in the change of hydrochemical and microbiological parameters in shallow waters of Lake Baikal in the areas of recreation and commercial use. The content of mineral forms of nitrogen and phosphorus in water samples was insignificant (up to 1.53 mg N/L -1 and 0.36 mg P/L 1). The content of chlorophyll in the researched water sites varied from 0.004 to 1.166 mg/L -1. In the areas of selection, where low concentrations of mineral nitrogen and phosphorus, essential for the formation of biomass, were recorded, a relatively high content of chlorophyll a was found, which indicates activity of the microbial community in this ecosystem.
