Figure 4.

(A) Predicted crayfish tissue PAH concentrations compared to measured concentrations expressed in wet tissue weight and (B) close-up view of measurements near method detection limits for four representative PAHs. Data points represent (●) average site concentrations calculated by inputting “zero” for measurements ≤ MDLs and (○) average site concentrations calculated after inputting MDLs for measurements that were below detection. The diagonal 1:1 reference line indicates perfect prediction.
