Industrial activities in the Jiu River basin, especially coal mining, have generated a significant impact on water quality over time, by releasing variable concentrations of heavy metals into the environment. This paper analyzes the trends of variation over time of the degree of heavy metal pollution in the Jiu River, considering the direct influence of the extractive industry in the area. The study is based on data collected from multiple water quality monitoring campaigns, covering an extended period, and aims t...

The research investigates the impact of persistent organic pollutants, particularly pesticides, on the aquatic ecosystems of the Jiul de Est basin. Pesticides are introduced into water bodies via surface runoff, infiltration, and atmospheric deposition, and their bioavailability is influenced by factors such as pH, temperature, and dissolved organic matter. The research evaluates the ecotoxicological effects on key aquatic species, including Salmo trutta fario (river trout) and Squalius cephalus (common chub), by ...
