Contaminant concentrations for juvenile (n = 4), subadult male (n = 8), adult male (n = 6) and adult females (n = 2), in relation to ΣPCB, ΣPBDE and TEQs published toxicity threshold. (a) ΣPCB (mg/kg l.w.) concentrations in relation to published toxicity thresholds. The lower dotted line represents the lower toxicity threshold (9 mg/kg l.w.) published for marine mammals18,47. The dashed line represents the highest threshold (41 mg/kg l.w.) published for marine mammals48. (b) ΣPBDE (mg/kg l.w.) concentrations in relation to 1.5 mg/kg l.w. published toxicity threshold49. (c) TEQ concentrations (pg WHO-TEQ/g l.w.) in relation to 210 pg WHO-TEQ/g l.w. published toxicity threshold50.
