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 ...

Following the vehicle painting process, residual gases containing volatile organic compounds (VOCs) are released into the atmosphere through exhaust pipes. Entrepreneurs are legally obliged to report to the Environmental Protection Agency, which, in turn, reports to the European Union to reduce greenhouse gas emissions and achieve climate neutrality by 2050. The current paper investigates the temporal variation of VOC concentrations correlated with technological processes carried out in vehicle painting shops. Thr...
