Abstract
Context
Owing to the multiple functions of lipids and fatty acids in organisms, lipid composition can be used as an environmental biomarker of the health status of sentinel organisms in monitoring studies of aquatic ecosystems.
Aims
To study the lipid profile of the mussel Mytilus galloprovincialis from the Black Sea and to identify lipid compounds as environmental biomarkers.
Methods
Lipid and fatty acid compositions in the gills and digestive glands of mussels were analysed by chromatography.
Key results
Membrane-state fatty acid indices in phospholipids were quite stable in all the mussels examined. The fatty acid composition of triacylglycerols is primarily an indicator of the food source for mussels. The selective retention of arachidonic acid as well as the accumulation of non-methylene-interrupted fatty acids in mussels are assumed to be biomarkers of environmental stress.
Conclusions
The presence of regulatory mechanisms ensuring the stability of the membrane structure was confirmed in all studied mussels.
Implications
The content of minor phospholipid fractions (namely, phosphatidylinositol and sphingomyelin) and the distribution of some fatty acids and their indices among lipid classes in the gills and digestive glands of M. galloprovincialis can be used in the assessment of the health status of sentinel organisms.
期刊介绍：
Marine and Freshwater Research is an international and interdisciplinary journal publishing contributions on all aquatic environments. The journal’s content addresses broad conceptual questions and investigations about the ecology and management of aquatic environments. Environments range from groundwaters, wetlands and streams to estuaries, rocky shores, reefs and the open ocean. Subject areas include, but are not limited to: aquatic ecosystem processes, such as nutrient cycling; biology; ecology; biogeochemistry; biogeography and phylogeography; hydrology; limnology; oceanography; toxicology; conservation and management; and ecosystem services. Contributions that are interdisciplinary and of wide interest and consider the social-ecological and institutional issues associated with managing marine and freshwater ecosystems are welcomed.
Marine and Freshwater Research is a valuable resource for researchers in industry and academia, resource managers, environmental consultants, students and amateurs who are interested in any aspect of the aquatic sciences.
Marine and Freshwater Research is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science.
