Koros River Basin Water Quality Assessment

The aim of the study is the survey of some several chemical and physical parameters (ammonium, nitrites, nitrates, phosphates, temperature, pH, alkalinity, conductivity, hardness, chlorides, dissolved oxygen, CCOMn,) in the aquatic environment on along the Crisuri Rivers Basin around border between Romania and Hungary (Barcau, Crisul Alb, Crisul Negru and Crisul Repede Rivers). The necessity of this study appeared due to: the long tradition in mining activities in the area on Crisul Negru River, the long tradition in oil extraction and exploitation activities in the area on Barcau and other industrial activity’s and agricultural and household activity’s, that could be a source of ecosystems contamination.
