Water pollution by emerging contaminants such as antibiotics is a major and current problem in the field of environmental protection. The presence of these micropollutants in surface waters, even in low concentrations, disturbs the ecological balance and leads to the selection and increase of the antibiotic resistant bacteria incidence, so that the...

Danube River is of particular importance for countries whose territories it crosses, both economically but in its impressive biodiversity too. Thus, it is important to know the distribution of pollutants in certain areas of interest, in order to mitigate their expansion and to decontaminate the pollution prone zones. In this study was assessed an a...
