PAHs impacts on aquatic organisms: contamination and risk assessment of seafood following an oil spill accident

An Acad Bras Cienc. 2022 Jun 17;94(suppl 2):e20211215. doi: 10.1590/0001-3765202220211215. eCollection 2022.

Abstract

Oil spills, intrinsically related to the petroleum production chain, represent a risk to the marine environment and a potential threat to humans through seafood consumption. We revised the NE Brazil oil spill and other accidents along the Brazilian coast, with a focus on seafood contamination, covering topics such as bioaccumulation, bioaccessibility, and risk analysis. Comprehensive knowledge of the impacts of spills helps in the interpretation of the dynamics of hydrocarbons released into the sea, contributing to actions to control their negative impacts. Currently, no legal limits have been established permanently in Brazil for PAHs in seafood edible tissues.
