Figure 1

Survival (%) of Daphnia magna exposed to untreated olive mill wastewater (OMWW) and olive mill wastewater treated with the chemical precipitation technique (CPT-OMWW). The percentage (%) of values (mean ± standard error (SE)) is shown versus the tested water’s dilution.
Figure 2

(a) Survival (%) after 96 h of Danio rerio exposed to untreated olive mill wastewater (OMWW) and olive mill wastewater treated with the chemical precipitation technique (CPT-OMWW). Percentage (%) (mean ± SE) of values is shown versus olive mill wastewater concentration (%). Malformations in the three highest concentrations of OMWW are not presented in the figure due to 100% mortality. (b) Malformations (%) after 96 h of D. rerio exposed to untreated OMWW and CPT-treated OMWW. Percentage (%) (mean ± SE) of values is shown versus olive mill wastewater dilution (%).
Figure 3

(a) Enchytraeus crypticus reproduction (Left y-axis) and adult survival (Right y-axis) after 21 days, and (b) Folsomia candida reproduction (Left y-axis) and adult survival (Right y-axis) after 28 days exposed to different sludge application rates using different concentrations in soil (%). All values are presented as mean ± SE, and asterisks (*) signify statistical differences in comparison with the control (0%) (Dunnett’s, p < 0.05).
Figure 4

Roots and shoot biomass (mg, fresh weight, FW) of (a) Brassica oleracea and (b) Lolium perenne after exposure to different application rates using different concentrations of sludge in soil (%). Biomass value (mg) (mean ± SE) is shown versus sludge concentration (%). Asterisks (*) indicate statistical differences to the respective control (0%) (Dunnett’s, p < 0.05) for both root and shoot biomass of B. oleracea and shoot biomass of L. perenne (Dunn’s, p < 0.05) for root biomass of L. perenne.
Figure 5

Root and shoot length (cm) of (a) Brassica oleracea and (b) Lolium perenne after exposure to different concentrations of sludge. Length value (cm) (mean ± SE) is shown versus sludge concentration (%). Asterisks (*) denote statistical differences from the respective control (0%) (Dunnett’s, p < 0.05).
Figure 6

Root and shoot hydric content (%) of (a) Brassica oleracea and (b) Lolium perenne after exposure to different concentrations of sludge. Hydric content (%) (mean ± SE) is shown versus sludge concentration (%). Asterisks (*) denote statistical differences to the respective control (0%) (Dunnett’s, p < 0.05).
