Ecological Systems and Devices Annotation << Back EFFECT OF C60 FULLERENE WATER DISPERSION ON FUNCTIONAL CHARACTERISTICS OF CERIODAPHNIA DUBIA D.M. Gershkovich, G.A. Dallakyan Currently, fullerenes and their derivatives are intensively studied in experiments in vitro and in vivo, including in connection with the possibility of their use in biology and medicine. The description of the biological effects of fullerenes impact on aquatic organisms are fragmentary, while the results of such studies do not always agree with each other, describing the multidirectional effects. At the same time, the production of fullerenes and the probability of their release into the environment, including the aquatic environment, are increasing. Thus, the study of the effects of fullerenesaction inbiological systems, in particular – on aquatic organisms, becomes especially relevant. The paper describes the effects of the action of an aqueous dispersion of fullerene C60 at concen-trations of 0,1 and 1 mg/l on the biological indicators of the laboratory culture of planktonic crustaceans Ceriodaphniadubia. An experiment lasting 8 days showed a significant stimulating effect on survival, linear growth (up to 6 % compared with the control) and reproduction (up to 144 % compared with the control), as well as the acceleration of the onset of maturation of crustaceans. It should be noted that the appearance of juveniles (the first litter) was observed in the control group of individuals on day 6, and in the presence of fullerene in both cases somewhat earlier – on day 4…5, which indicates the stimulation of the onset of maturity in crustaceans in experimental samples.
