Zusammenfassung: | 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. |
