Implication

Comparative assessment reveals elevated polybrominated diphenyl ether levels in farmed compared to wild salmon, suggesting commercial feed and higher trophic positions drive contaminant exposure.

Key Points

To measure and compare polybrominated diphenyl ether (PBDE) contamination in farmed and wild salmon across different global aquaculture regions and species.
Quantified polybrominated diphenyl ether (PBDE) concentrations in farm-raised salmon across production regions in Europe, North America, and Chile.
Evaluated PBDE contamination across multiple species of wild salmon and assessed differences in relation to adult body size and trophic level feeding patterns.
Farmed salmon exhibited higher PBDE levels than wild salmon, with European farmed stocks demonstrating greater contamination than North American farmed stocks, and both exceeding Chilean farmed stocks.
Chinook salmon had significantly elevated PBDE levels relative to other wild salmon species, consistent with their larger adult size and higher feeding position within the marine food web.
