“…Кроме того, в гепатопанкреасе моллюсков происходит накопление, детоксикация и выведение ксенобиотиков различной природы. Известно, что нефтяные углеводороды могут накапливаться в тканях морских животных, богатых липидами, и вызывать модификации на уровне их липидного состава (Capuzzo, Leavitt, 1988;McDowell et al, 1999;Nechev et al, 2002). В настоящей работе было показано, что изменения липидного состава в гепатопанкреасе мидий определяются соленостью морской воды, а также концентрацией нефти и продолжительностью ее воздействия.…”

The response of the organism to the pollutant impact is influenced by a variety of abiotic and biotic environmental factors that may have a synergistic or antagonistic effect on the biodegradation, accumulation, distribution and elimination of the xenobiotics. It is known that lipophilic organic contaminants including oil hydrocarbons can be accumulated in lipid-rich tissues of marine animals, thus causing changes in biosynthesis and transport of phospholipids and triacylglycerols, as well as in the physical state of biological membranes. The cooperative effect of crude oil and low salinity on digestive gland lipid composition of the White Sea blue mussels Mytilus edulis L. was studied in aquarium experiment. Low salinity (15‰) impact reflects on the lipid composition indicating high energy costs directed to acclimation of the mussels to new environmental conditions. However, the response of the lipid composition on the crude oil effect is almost not dependent on the ambient salinity, and is mainly determined by exposure duration to crude oil and its dose in aquarium water. On the third experimental day a significant increase in the cholesterol/phospholipids ratio and the subsequent its recovery to initial level possibly indicate the development of the protective compensatory mechanisms to provide low permeability of cell membranes in digestive glands under crude oil pollution. It was observed that the leading factor contributing the lipid composition modifications in blue mussel digestive glands is crude oil effect, mainly in its higher concentrations.

“…[17] The crude oil and diesel fuel may change membrane fluidity of some phytoplankton species through interference with cell membrane constitutes. [18] In addition, toxic compounds of crude oil can restrict nutrient uptake, photosynthesis, and some other biochemical processes resulting in reduced growth of algae. [19,20]…”

The capability of Scenedesmus dimorphus for biodegradation of crude oil components is evaluated using biological and biochemical techniques. After exposure of the algal cells to different concentrations of crude oil for 21 day, growth parameters such as cell number as well as fresh and dry weights have increased at low concentrations of crude oil (up to 0.04%) in comparison with control samples. However, growth criteria have decreased in response to the increase in crude oil concentration (0.08%-1%). Similar trends are observed in the content of chlorophylls, carotenoids, flavonoids, anthocyanins, and phenols. Crude oil treatment induces the production of H 2 O 2 and thiobarbituric acid reacting substances. Moreover, enhancing crude oil concentration results in increasing activities of superoxide dismutase, polyphenol oxidase, peroxidase, and lipoxygenase. In comparison, the activities of catalase, ascorbate peroxidase, and phenylalanine ammonia lyase increase at low concentrations (up to 0.02%) and then decrease. Using gas chromatography-mass spectrometry analysis several biodegradation intermediate compounds are recognized in the culture media over treatment time. Altogether, S. dimorphus shows considerable potential for biodegradation of crude oil components particularly at concentrations lower than 0.08%. Thus, this microalga can be used as a competent phytoplankton in removal of crude oil from contaminated water supplies.
