Study of physico-chemical parameters of surface waters in the Lana river, Albania

Abstract

The water quality in the Lana River has been and currently is under the influence of a number of factors. However, we emphasize that the main impact comes from anthropogenic activities, exactly pollutation from discharges of urban wastewater. This article presents the results of the study of the physical and chemical parameters of surface waters in the Lana River. The study report discusses about the analysis of river water quality. The water samples for this study, taken were carried out on four expeditions in the months of May, June, July, September 2016, at five monitoring stations at: the upper part of the river flow (Lanabregas) , the middle stream of the river (New Maternity and Palace with Arrow ), and downstream of the river, (Yrshek - ex Customs and Domje). Collection, preservation and conservation of samples was carried out in accordance with the recommended standard methods. Parameters: temperature, electrical conductivity, pH, DO, and % DO were analyzed directly on the site using WTW Multimeter 3420 Set G apparatus. Other chemical parameters were analyzed in the Chemistry Laboratory of the Faculty of Mathematical Engineering and Physical Engineering based on recommended standard methods. The obtained results showed high values of the quality parameters studied, and compared to international standards such as NIVA classification, UNECE, and EU standards, the Lane River waters are of very bad environmental quality. At the conclusion of this study, we recommend, establishing a continuous monitoring system of water quality studied and strengthening the controls of urban waste-free discharge in the river.
