Fig. 4 — Hydra toxicity from As (III, V) (A), Cd (II) (B), Hg (C), Pb (II) (D) and a metal mixture (0.2 ppm/metal) (E)and protection by sorbents at an inclusion rate of 0.1% Hydra media and metal controls are included for comparison Data represent the mean morphological score at each time point, run in triplicate (* p ≤ 0.05, ** p ≤ 0.01)
