EVALUATION OF ECOLOGICAL STATUS OF THE SHKUMBINI RIVER BASED ON BIO-CHEMICAL INDICATORSLirika Kupe, Aida Bani Oljan Dervishi, Ilir Kristo and Edmira ShahuAbstract Aims of this paper is the water quality assessment using bio-chemicals monitoring techniques, during July and September 2015, for the Shkumbini River, located in central Albania. Purpose is to provide more information about the ecological status and protection of these ecosystems. In this study from algae community, we used diatoms for Biomonitoring because they have a siliceous frustule. Three different indices (SI, TIDIA and Hâ) were used for biological evaluation. Based on diatom community structure, Shkumbini water quality was classified from mesotrophic to polytrophic, which shows a high status of eutrophication. Concentration of total phosphorus and nitrogen were used for the evaluation of trophic status for all sampling stations. This situation is due to the presence of inorganic and organic matter, originated from agricultural activity, restaurants, urban waste discharge and erosion by inhabitant centres. |
