(A) Principal Component Analysis (PCA) of relative content of each PAH by sampling site, separated along the PC1 axes. Ellipses are generated at the 95% confidence limit leaving nine sites with high contents of PAH (yellow circles) and 22 sites with predominantly low PAH content (blue triangles). (B) Environmental fitting (Envifit) built onto the PCA of parameters %C, %N, water depth, protein as THAA, δ13C, δ15N, and relative content of low and high MW-PAH.
