What is it about?
This study examines whether acute waterborne exposure of sea bream (Sparus aurata) to benzo[a]pyrene (B[a]P), a polycyclic aromatic hydrocarbon, leads to contaminant accumulation in edible muscle. It also tests whether organic extracts from contaminated fish muscle exert cytotoxic effects on human peripheral blood mononuclear cells (PBMCs) in vitro.

Why is it important?
PAHs are lipophilic contaminants that can bioaccumulate along the food chain. The work links environmental contamination to potential human health relevance by combining in vivo fish exposure with ex vivo testing on human blood cells, highlighting a possible dietary risk.
Perspectives
The exposure scenario reflects high, acute contamination (e.g., spills), and human data derive from in vitro PBMC assays, showing modest but measurable effects. Real‑world exposure involves mixtures of PAHs and other pollutants, suggesting that combined effects may be underestimated and warrant further study.
