Figure 1

Correlogram of Spearman correlation test performed between pedological properties and soil PTE (metal and metalloid pseudo-total concentrations in mg/kg) measured at both soil depths (0–10 cm and 10–20 cm). Blue dots correspond to the positive correlations and red dots to the negative correlations. The size and color intensity of the dots are proportional to the correlation coefficient value. Parameters: CEC = cation exchange capacity; NTK = total Kjeldahl nitrogen; TC = total carbon; IC = inorganic carbon; TOC = total organic carbon; SIR/BR = substrate-induced respiration/soil basal respiration.
