Figure 4.

Toxicity of soils treated under different configurations. The toxicity values were represented as inhibition of P. subcapitata algal growth (%) at different incubation times: 7 days (●) and 20 days (○). Reference non‐toxic value was also provided (green line) to lower toxicity. The incubated soils under pol‐MERC treatment during 7 and 20 days showed an inhibition below the non‐toxic value, in contrast with the rest of the treatments, above non‐toxic level.
