- W2076755325 abstract "Daphnia magna was exposed to some nominal sublethal tetradifon concentrations (0.10, 0.18, 0.22 and 0.44 mg/l) during 21 days. Chronic toxicity tests were carried out using neonates of F(1) first brood (F(1)-1st) and F(1) third brood (F(1)-3rd) offspring generations from parentals (F(0)) pre-exposed to the pesticide. The effect of tetradifon on survival, reproduction and growth was monitored for the selected daphnid generations. The parameters used to evaluate pesticide effect on reproduction were: mean total young per female, mean brood size, time to first reproduction, mean number broods per female and intrinsic rate of natural increase (r). Survival and growth (body length) were also determined after 21 days of exposure to the pesticide. Reproduction was significantly reduced when tetradifon concentration increased in the medium. This effect was higher in F(1)-1st and F(1)-3rd offsprings compared to the parental generation (F(0)) daphnids. The intrinsic rate of natural increase (r) decreased with increasing concentrations of tetradifon especially in those animals from F(1)-3rd. However, the growth of the exposed organisms decreased in the same order of magnitud in all the generations tested. Survival was not affected after exposure to the selected tetradifon concentrations. The maximum acceptable toxicant concentration (MATC) was calculated for F(0), F(1)-1st and F(1)-3rd generations exposed to the pesticide using as parameter of evaluation the intrinsic rate of natural increase (r). The interpolation of these results gave MATC values of 0.13 mg/l pesticide for F(0) and F(1). The EC50 values have been derived for some selected parameters on D. magna exposed to tetradifon. EC50 values decreased in F(1)-1st and F(1)-3rd generations compared to the parental generation F(0), these results mean that less amount of toxicant would be necessary to reduce the selected parameters to 50% in the first and third broods of D. magna. Expanding the reproduction tests to several broods of a parental generation revealed important information on chronic toxicity that could be used in the protection of aquatic environment." @default.
