Diagnostic ratio charts based on polycyclic aromatic hydrocarbon (PAH) concentration data (wet weight) measured in stranded Southern Resident killer whales (SRKW; O. orca) and Bigg’s killer whales. (a) Flu/(Flu + Pyr) and Ant/(Ant + Phe) for skeletal muscle samples, (b) Flu/(Flu + Pyr) and BaA/(BaA + Chr) for skeletal muscle samples, (c) Flu/(Flu + Pyr) and Ant/(Ant + Phe) for liver samples, (d) Flu/(Flu + Pyr) and BaA/(BaA + Chr) for liver samples. Note: Ant anthracene, Phe phenanthrene, Flu fluoranthene, Pyr pyrene, BaA benz[a]anthracene, Chr chrysene. See Table S3 for diagnostic ratio values.
