Determination of anthropogenic impact on the Siret River and its tributaries by the analysis of attached algae / Określenie antropogenicznych oddziaływań na rzekę Siret i jej dopływy poprzez analizę osiadłych glonów
The article is devoted to the determination of anthropogenic impact on the Siret River and its tributaries (the Sukhyj, the Mikhidra and the Malyj Siret Rivers). The taxons of attached algae were determined in this case. Then they were distributed in the saprobity groups and the correlation of each group was found. It was necessary to identify the stage of ecological regress on each site of the researched basin. The data about the ecological regress can be used as primary information on the aquatic ecosystem state for conducting the further researches. The next step of the investigations was counting of the saprobity index by Pantle and Bukk in Sladechek modification for classification of quality status of water in the researched basin.
