Abstract
The paper presents a study that was focused on the analysis of the existence of metals in the rivers located near the salt mine Targu Ocna, Romania. The points identified near mining areas and the proposal for performing analyzes regarding the presence of metals in surface waters are the Slanic River and the Trotus River. The purpose of this study is to analyze the physico-chemical parameters: (pH, electrical conductivity, dissolved oxygen, turbidity, temperature), selected heavy metals (Fe, Mn, Zn, Cr), Mg and Al of the Slanic River and the Trotus River located near the salt mine and to investigate the level of metal contamination due to mining activities. The samples were collected at two points in the Slanic River and two points for the Trotus River. The physico-chemical parameters were measured in-situ with portable equipment and within the Water Analysis Laboratory of “Vasile Alecsandri” University of Bacau. The values registered for the physico-chemical parameters were compared with the permissible limits by the legislation.
