The Concentrations of Polycyclic Aromatic Hydrocarbons in Fish: A Systematic Review

Andre Vieira Kuhn (SuperTCC), Helen Henrique (Santa Cecilia University), Natheili Cozer, Giorgi Dal Pont, The Concentrations of Polycyclic Aromatic Hydrocarbons in Fish: A Systematic Review (2023):

A study assessed PAH concentrations, specifically benzo[a]pyrene and a quartet of PAHs (benz[a]anthracene, chryseno, benzo[b]fluoranthene, and benzo[a]pyrene), in untreated fish tissues. Correlations were drawn between values, temporal spans, regions, lifestyles, diets, and habitats of fish species. Data were contrasted with limits from U.S. EPA and E.U. regulations. PRISMA systematic review (1982-2020) was used, focusing on PAH concentration data. Notably, China, Nigeria, and Iran contributed the most studies. Prominent bioindicators were Coptodon zillii, Siganus punctatus, and Liza Abu. Demersal and pelagic fish exhibited elevated PAH levels. While instances of surpassing benzo[a]pyrene and PAH limits occurred, many findings remained within European consumption standards.
