Ecological Diagnosis of Bega River Water Quality Depending on the Topography of Timisoara City

Abstract

Human impact in various forms changes the water quality parameters and disturbs the environmental living of saprobionte organisms. The present study follows the ecological parameters of the saprobionte organism as a diagnostic method of Bega river water quality in the area of Timisoara city. In August 2014 in the Bega River were collected 20 quantitative samples of benthic zones, in order to highlight the links between pollution degree and the saprobionte organisms community. Samples were collected from the upstream, middle and downstream of Timisoara city. After the identification of saprobionte organisms, have been performed the density, abundance and frequency of the sample. Based on these values, we can say that the upstream segment waters falls into the category of superior quality compared to the waters of the central segment, especially in the downstream segment.
