Abstract
This paper aims at underlying some physico - chemical, chemical and biological characteristics of the water in the Nicolina River in Iasi city area. 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 (pH, conductivity, TDS) according to the interval of time and the station of water sampling. The water pH is mainly slightly alkaline; The conductivity and TDS values indicate a high degree of mineralization. We identified 74 taxa of algae belonging to six groups: Cyanophyta, Bacillariophyta, Euglenophyta, Zygnematophyta, Chlorophyta and Chrysophyta. The results obtained and the algal taxons identified underlie the existence of some human influence on the river water in the analysed sector.
