PRELIMINARY ASPECTS REGARDING SOME PHYSICO-CHEMICAL AND BIOLOGICAL CHARACTERISTICS OF THE WATER BISTRI A RIVER (LOWER COURSE)

This paper aims at underlying some physico-chemical, chemical, and biological characteristics of the water in the Bistri a River in the sector Piatra Neam – Podoleni. Field observations and physical – chemical and chemical analysis of water samples were performed; the species of algae were identified. The results obtained emphasize specific values of the analyzed indicators (temperature, pH, conductivity, TDS) according to the interval of time and the station of water sampling. Water samples collected from the Roznov and Podoleni stations presents high values of conductivity and TDS throughout the period studied. The species of algae identified in the water samples belong to the groups Cyanophyta, Chrysophyta, Bacillariophyceae; Euglenophyta, Chlorophyta.
