Occurrence and Risks of Per- and Polyfluoroalkyl Substances in Shellfish.

ABSTRACT:

Purpose of review

Per- and polyfluoroalkyl substances (PFAS) are a diverse class of persistent, fluorinated surfactants used widely in industrial and commercial applications with known adverse health effects. Seafood consumption is thought to be an underappreciated source of PFAS exposure in the general population. This review synthesizes the current understanding of PFAS occurrence in shellfish, a term used to describe animals such as mollusk bivalves, certain gastropods (snails), cephalopods (e.g., octopuses and squid), and crustaceans, and highlights scientific gaps relative to bioaccumulation and the protection of shellfish consumers.

Recent findings

A range of sampling methodologies are used across studies, and the suite of PFAS surveyed across studies is highly variabl
