“…Many studies have shown that phytoplankton ingests arsenic from water, consistent with our data [33][34][35][36]38,58]. Other studies report the form of arsenic in phytoplankton is predominantly a mixture of arsenate with a small percentage as arsenite.…”

“…and a carnivore (goldfish, Carassius sp.) [36], water arsenic levels of 30 and 100 mg L −1 resulted in alga arsenic concentrations of 745 and 2850 mg kg −1 , respectively. More than 98% of the algae arsenic was found to be non-methylated inorganic.…”

“…1). Maeda et al (1990) conducted a laboratory experiment using an alga-zooplanktongoldfish freshwater food chain. The TTC value for phytoplankton to zooplankton was 0.1 and from zooplankton to goldfish 0.2, indicating that biomagnification of arsenic was not occurring.…”

“…Direct accumulation, transformation and transfer are responsible for the sublethal and acute toxicity observed in the higher trophic levels of arsenic. Our previous studies [4][5][6][7] have clarified the importance of freshwater food chain in the toxicity of arsenic on some freshwater organisms. The lethal concentrations for As(V) obtained by these studies were shown in Table I.…”

The bioaccumulation and biotransformation of arsenic compounds by freshwater Daphnia magna (D. magna) including its tolerance against arsenicals were investigated. When D. magna was exposed to a medium containing arsenicals, total arsenic metabolite in cell increased with an increase in the arsenic concentration in the medium. D. magna accumulated total arsenic in their cells higher from the medium containing arsenate [As(V)] than from medium containing arsenite [As(III)]. No methylation occurred when D. magna was exposed to methylarsonic acid (MAA) and dimethylarsinic acid (DMAA). Trimethylarsenic species was not detected in cells. Lethal concentration of D. magna against As(III), As(V), MAA and DMAA were 1.7, 5, 12 and 250mg As/L, respectively. No toxic effect of arsenic-containing algal diets on the growth of D. magna was observed up to 1130 mg As/kg.
