Intestinal alterations in European sea bass Dicentrarchus labrax (Linnaeus, 1758) exposed to microplastics: Preliminary results

Frequency of Microplastics in Mesopelagic Fishes from the Northwest Atlantic

“…Microplastics have previously been shown to adversely impact invertebrate species such as lugworms, causing weight loss, reduced feeding activity and inflammation (Besseling et al, 2013;Wright et al, 2013), and detrimental effects on the intestinal functioning of seabass (Dicentrarchus labrax) have also been noticed (Pedà et al, 2016). Furthermore, there is growing concern about the effect of chemical pollutants sorbed to microplastics.…”

“…Indeed, Gall and Thompson (2015) have reported that over 690 marine species are impacted by marine litter. More recent studies have moved from quantifying which animals have ingested microplastics to examining the physical and health implications of microplastic ingestion (Rochman et al, 2013;Cole et al, 2014;Pedà et al, 2016). For example, Wright et al (2013) demonstrated how the ingestion of microplastics by the polychaete Arenicola marina (lugworm), an important ecosystem engineer of Northern Europe's intertidal zones, caused inflammation and decreased feeding and ultimately depleted energy reserves.…”

“…Plastics gradually break down to microscopically small particles, but these may pose an even more serious problem (Thompson et al 2004;Bergmann et al 2015). Although experimental results and model predictions are not all in agreement, concerns about microplastics are increasing as plastics can adsorb and concentrate organic pollutants from the surrounding water and, once ingested, might release chemicals into marine organisms with associated negative effects (Arthur et al 2009;Browne et al 2008Browne et al , 2013Endo et al 2005Endo et al , 2013Gouin et al 2011;Koelmans et al 2013aKoelmans et al ,b, 2014Koelmans et al , 2016Moore 2008;Teuten et al 2007Teuten et al , 2009Chua et al 2014;Rochman et al 2013Rochman et al , 2014aTanaka et al 2013;Thompson et al 2009;Van Cauwenberghe & Janssen 2014;Cole et al 2015;Watts et al 2015;CBD 2016;Beaman & Bergeron 2016;Peda et al 2016;Besseling et al 2017;Heindler et al 2017;Hermabessiere et al 2017;Ribeiro et al 2017). Thus, in addition to the toxic substances incorporated into plastics in the manufacturing process, plastics may concentrate pollutants from the environment and act as a pathway adding to their accumulation in marine organisms.…”

Microplastic occurrence and effects in commercially harvested North American finfish and shellfish: Current knowledge and future directions

“…Effects include oxidative and hepatic stress, modified predatory behaviors, reduced energy reserves, decreased lipid metabolism, and the potential for endocrine disruption (Cedervall et al 2012;Rochman et al 2014;de Sá et al 2015;Lu et al 2016;Yin et al 2018). For example, the European sea bass (Dicentrarchus labrax), a commercial species in the Mediterranean Sea, exhibited pathological alterations to its intestinal epithelium following a 30-90 d exposure to untreated and polluted PVC microplastic pellets, suggesting that microplastics and POPs can have a significant negative effect on fish health (Pedà et al 2016).
