Average toxicity (± SE) caused by the dissolved galvanic anode and its main components aluminum and zinc to C. volutator. Test organisms were exposed to the different metal concentrations for ten days with (w/) sediment and 3 days without (w/o) sediment. The numbers below the bars represent the number of replicates of each experiment. Experiments with statistically significant differences to the corresponding negative control are marked with an asterisk (two-tailed unpaired t-test, p < 0.01). See Additional file 1: Table SI11 for complete data of statistical evaluation
