- Abstract
This study reported the chemical and microbiological composition of a sector of Pasărea River, Romania, comprising the Dimieni Bridge (DB) and Tunari Dam (TD) sites, in relation with the chemical and microbiological pollution of this tributary of River Dâmbovița. The amount of sulfate-reducing bacteria (5.75x107 cells/mL at DB and 5.5x107 at TD), nitrite and nitrate bacteria (3x10 cells/mL at DB and 3x10³ at TD), total coliforms (2,5x10 C.F.U./mL at DB and 2.25x10 at TD) and faecal streptococci (5x10³ C.F.U./mL at DB and 1.4x10² at TD) revealed a relatively high cell density of microbial groups considered indicators of microbiological pollution. The analysis of the chemical composition highlighted the presence of chromium, cerium, aluminium and barium oxides in the 10 – 20 % range at DB in winter and in the 20 – 70% range at TD during spring confirming the chemical pollution of the analysed river sector. These contents were in accordance with values that could sustain the development of a polluting microbial community. Based on the corroborated data, the current survey proposed a set of criteria for establishing standards for the microbiological and chemical pollution of fresh water relative to drinking water values
