Peak constituents of the optimal classification models for gills (A) and digestive gland (B) of Blue mussels exposed to 0.5 mg/L crude oil (oil) and 0.5 mg/L crude oil spiked with a mixture of APs and PAHs (0.1 mg/L; sO) for 21 days. The score equals the discriminatory weight of the variable within the classifier. A pre-selection of highly significant peaks (p < 0.001) has been carried out prior to model construction.
