The occurrence of eight organic UV filters (UV-Fs) was assessed in fish from four Iberian river basins. This group of compounds is extensively used in cosmetic products and other industrial goods to avoid the damaging effects of UV radiation, and has been found to be ubiquitous contaminants in the aquatic ecosystem. In particular, fish are considered by the scientific community to be the most feasible organism for contamination monitoring in aquatic ecosystems. Despite that, studies on the bioaccumulation of UV-F are scarce. In this study fish samples from four Iberian river basins under high anthropogenic pressure were analysed by liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Benzophenone-3 (BP3), ethylhexyl methoxycinnamate (EHMC), 4-methylbenzylidene camphor (4MBC) and octocrylene (OC) were the predominant pollutants in the fish samples, with concentrations in the range of ng/g dry weight (d.w.). The results indicated that most polluted area corresponded to Guadalquivir River basin, where maximum concentrations were found for EHMC (241.7 ng/gd.w.). Sediments from this river basin were also analysed. Lower values were observed in relation to fish for OC and EHMC, ranging from below the limits of detection to 23 ng/gd.w. Accumulation levels of UV-F in the fish were used to calculate biota-sediment accumulation factors (BSAFs). These values were always below 1, in the range of 0.04-0.3, indicating that the target UV-Fs are excreted by fish only to some extent. The fact that the highest concentrations were determined in predators suggests that biomagnification of UV-F may take place along the freshwater food web.

“…The resistance first appears in a certain population, usually where the insecticide has been used most intensively, as can be seen at IR dam. Most resistance strains owe their survival to the ability to detoxify insecticides (Sancho et al, 1998). The ability to detoxify such insecticides is crucial to the survival of organisms.…”

“…Pesticides are very toxic compounds, widely used in agriculture, which have been shown to cause many toxicological and environmental problems (Younes and Galal-Gorchev, 2000;Sancho et al, 1998;Bassi et al, 1996;Chemnitius et al, 1996;Maines et al, 1996). Due to the large number of pesticides used nowadays, there is an increased interest that sensitive, selective and reproducible, high-throughput screening systems be developed for their determination.…”
