Title: Accumulation and regulation of zinc in Daphnia magna: Links with homeostasis and toxicity
Abstract: Zinc accumulation in Daphnia magna was investigated, and the results were linked to the previously established optimal concentration range for zinc and D. magna. It was observed that organisms cultured in this optimal range (300-600 μg Zn/L) contained 212 ± 57 to 254 ± 79 μg Zn/g dry weight. Lower and higher zinc contents were obtained after acclimation to previously established culture concentrations inducing deficiency and toxicity, respectively. The calculation of bioconcentration factors indicated that zinc was actively regulated, at least up to a concentration of 600 μg Zn/L. Zinc uptake and elimination are rapid processes; major increases and decreases in body content occurred within I day. Zinc concentrations in daphnids exposed to 600 μg Zn/L fluctuated with 2-to 3-day intervals, suggesting a role of molting in the regulation and elimination of zinc.
