Percent contribution of the 10 most abundant PAHs to ΣPAH in 2003 (A.), ΣPAH in 2013 (B.), ΣBaPeq in 2003 (C.), and ΣBaPeq in 2013 (D.). PAHs were measured in crayfish viscera collected in the Portland Harbor Superfund Megasite (PHSM) in the Willamette River in Portland, Oregon. The top 10 PAHs contributing to ΣBaPeq in PHSM crayfish viscera are nearly identical in 2003 and 2013. The only PAHs that contribute substantially to both ΣPAH and ΣBaPeq are fluoranthene (2003 and 2013), and chrysene (2003). All tissue concentrations are in ng/g wet weight.
