Mean cadmium concentrations in <i>G. pulex</i> body tissues (µg. g dry weight⁻¹).

<p>Concentrations obtained for individuals exposed 96 h to different conditions (control, arsenate, cadmium and four binary mixtures) at three temperatures (5-10-15°C). <b><i>a) Temperature × condition effect</i></b><i>.</i> Mean internal Cd concentrations <i>in G. pulex</i> for each tested condition and temperature. Vertical bars represent standard deviations. <b><i>b) Condition effect:</i></b> Weighted mean concentration of internal Cd for each tested condition (results for all the tested temperatures were combined). Vertical bars represent 0.95 confidence intervals. <b><i>c) Temperature effect:</i></b> Weighted mean concentration of internal Cd for each temperature (results for all the tested conditions were combined). Vertical bars represent 0.95 confidence intervals. Letters (a to g) were used as labels to illustrate significant differences in mean [Cd] values (two-way ANOVAs + LSD Fisher post hoc tests; at p<0.05 level of significance).
