DNA strand breakage in mussels (Mytilus edulis L.) deployed in intertidal and subtidal zone in Reykjavík harbour.
Mar Environ Res. 2004 Aug-Dec; 58(2-5):763-7.ME

Abstract

DNA single-strand breaks were analysed in the blue mussel (Mytilus edulis L.) deployed in intertidal and subtidal zones in the PAH contaminated Reykjavík harbour and at a reference site, Hvalfjörethur, Iceland. DNA strand breaks were analysed by Comet assay in isolated gill and haemocyte cells from six mussels from each site and depth. Increased DNA damage in both gill cells and haemocytes were observed in mussels deployed in Reykjavík harbour compared to the reference site. Intertidal mussels from Reykjavík harbour had higher DNA damage in haemocytes compared to subtidal mussels. The Comet assay seems to be useful for measuring genotoxic exposure in mussels from the field, and that DNA damage might be higher in the intertidal zone either due to higher exposure to contaminants or because of physiological and biochemical responses to variations in oxygen availability.
