Аннотация: The paper gives the results of the laboratory experiments on the influence of different concentrations of oil in water environment over the chlorella and daphnia. It is shown that as the oil content in water increases, the intensity of delayed fluorescence of test-culture of chlorella and the survival rate of the daphnia decrease. Показать полностьюHowever, for the chlorella the decrease in fluorescence as the indicator of its photosynthetic activity is observed only at very high concentrations of oil (1000-2000 MPC), whereas the survival rate of the cladocerans begins to drop at 4 MPC. A similar dependence is observed when sunflower-seed oil is introduced into the environment as an imitator of the oil pollution. We suppose that the negative influence of oil over the microalgae and cladocerans is conditioned more by the physical factors than by chemical ones.
