An ecotoxicological approach with transplanted mussels (Mytilus galloprovincialis) for assessing the impact of tyre reefs immersed along the NW Mediterranean Sea.
Tyre artificial reefs were deposited in a marine protected area (Vallauris-Golfe Juan Bay, France) located along the NW Mediterranean coast, during the early 80's. The potential toxic effects of the tyre artificial reefs were investigated using transplantation of marine mussels, Mytilus galloprovincialis, to stations located above tyre blocks (St1, St2) or reference site (StR). Mussels transplanted to different stations presented the following sequence of mortality: St1 > St2 > StR. Principal Component Analysis, taking into account metal accumulation (cadmium, copper and zinc) and biomarker (SOD, CAT, GST and AChE activities, TBARS and MT levels, Condition Index) responses in mussel tissues indicated a clear separation between the three stations. St1 organisms were significantly more affected by tyre reefs than those from other stations. Such an integrated monitoring study represents a key approach to assess in situ the biological impact of >25 year-old tyre artificial reefs.
