*2.9. Statistical Analysis*

Data referred to the phytoextraction test are reported as the mean of three replicate microcosms, and analyses were performed in triplicate, recording the mean value ± standard deviation ( ±SD). Data statistical analyses were performed using Statistica version 6.0 (StatSoft, Inc., Tulsa, OK, USA). Treatment effects were analyzed using a one-way analysis of variance (ANOVA, San Francisco, CA, USA). Differences between means were compared, and a post hoc analysis of variance was performed using Tukey's honestly significant difference test (*p* < 0.05).
