“…Water pollution is one of the most important environmental problems faced by water managers [1][2][3]. The problem is particularly evident in large river basins that are international in nature [4][5][6].…”

“…Low flows mean less dilution volume and hence higher concentrations of pollutant discharges [14,15]. In addition, an increase in water abstraction-water taken to meet the demands of human activities (drinking water supply, irrigation of agricultural areas, supplying various industries) contributes to the reduction of water resources enabling the normal functioning of river ecosystems [1]. Any change in temperature affects the river's ability to purify itself by reducing the amount of oxygen that can be dissolved and used for biodegradation [16].…”

This review paper aims to analyze studies conducted over recent years (2011–2021) on hydrocarbon pollution in the Danube’s Romanian sector. This involves looking at three main issues: Space-related Romanian Danube hydrocarbon pollution; the nature of samples and the types of tests used for hydrocarbon authentication; hydrocarbon effects on bioindicators and fish cell lines. The papers extracted for this review were selected from three scientific article platforms: Web of Science, Science Direct, and Google Scholar, by using keywords, a specific search protocol and various selection filters. The main results of the present analysis are the following: the highest levels of hydrocarbon contamination in suspended particulate matter and sediments were found in the sector Iron Gates-Călărași (2013), and the main pollution sources were industry, navigation and wastewater discharges; sediment and biological samples accumulate higher concentrations of hydrocarbons than water samples, and are a good indicator for these pollutants’ presence; the most widely used bioindicators are aquatic worms, mollusks, crustaceans, the wild common bleak, and, in the laboratory, fish cells; various methods are used in order to confirm hydrocarbon presence and/or their effects on biota: fluorescence, comet assay technique, micronucleus test, complementary passive samplers, in vitro bioassays, fugacity-based calculation model, sensors, oil spill modeling.
