Bioaccumulation of organochlorines in relation to the life history in the white-spotted charr Salvelinus leucomaenis

► The ecological risk for organochlorines (OCs) was examined in both anadromous and fluvial salmonids. ► A positive correlation between the lipid content and the OCs concentrations was observed. ► The OCs levels in the anadromous fishes were significantly higher than those in fluvial fishes. ► Anadromous salmon have a higher ecological risk for OCs exposure than the fluvial fish.
