Relative expression changes of differentially expressed peptides and proteins in the digestive gland of Blue mussels following 21d exposure 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) in % of control intensity; *, significantly different at 0.05 ≥ p ≥ 0.01, **, at 0.01 ≥ p ≥ 0.001, ***, at p < 0.001. Dotted bars indicate differential expression occurring in one of two exposures only.
