Variation of content of lipid classes, sterols and fatty acids in gonads and digestive glands of Scrobicularia plana in relation to environment pollution levels

► Energy metabolism may be disturbed due to the cost of tolerance in contaminated media. ► So lipids were studied in bivalves from sites differing by their level of pollution. ► PCA of lipid classes and biometrical indices reveals clearly intersite differences. ► Adding contamination parameters enhances these intersite differences. ► TAG and glycolipid % were linked, respectively, with dioxin and PAH and estrogen levels.
