Enzymatic activities measurements performed along the study during 8 months. (Aa) show dehydrogenase activity, (Bb) show phosphatase activity and (Cc) shows β-glucosidase activity assessed on Control pristine soil (filled circle), Control burnt soil (filled diamond), Bioremediation (triangle) and Rhizoremediation (square), and plants control (circle). A–C data are shown as mean (n = 3) and error bars refer to standard deviations. a–c data are shown as mean (n = 3), vertical boxes show the median (solid line), mean (dash line) and the 5th/95th percentiles.
