Persistent organic pollutants in tissues of farmed tuna from the Adriatic Sea

This study investigated the levels and distribution of polychlorinated biphenyls (PCBs) and organochlorine pesticides in three tissue types of farmed Bluefin tuna (Thunnus thynnus): muscle, liver and branchiae. Seven adult species were caught in 2015 at a tuna farm in the Croatian Adriatic. The organochlorine compound levels decreased in the following order: liver>muscle>branchiae while contaminant distribution in all three tissues followed the same order: ΣPCB ≫ ΣDDT>ΣHCH ~ HCB. The found POP levels indicated moderate pollution of farmed tuna and were below all limits set by current laws. Furthermore, no cytotoxic effect of the POP mixture extracted from tuna liver samples on human neuroblastoma cells was observed.
