Within this context, the present study aimed to clarify (i) the spatial distribution of PTE contents released from 100 m<sup>3</sup> of excavated shale deposited in a temporary storage pit, and (ii) the geochemical parameters that control such distribution. A total of 50 shale samples were collected from a temporary storage pit of rocks.

No linear relationship was detected between the released and total PTE amounts. An error of ± 30% was estimated based on a sample of 10 rocks. The geochemical parameters controlling the PTE contents released from the excavated shale differed depending on PTE types. The release of arsenic and selenium was mainly controlled by the amount of amorphous iron, while that of lead and chromium was controlled by the amount of inorganic colloidal particles with size under 0.45-μm. This study suggested that the preparation of 10 mixed rock samples collected from temporary storage pits leads to an estimation of released PTE amounts with a 30% error.

The study's main aim was to improve the understanding of the transfer dynamics of PTEs from soil to Primary Agricultural Products (PAPs). Unlike what has been done in several former studies, bioavailable fractions, instead of total concentrations, were used to assess transfer factors (TFs) of PTEs from soil toward PAPs. Further, the variability of some soil physicochemical characteristics such as organic matter (OM), grain size (GS), cation exchange capacity (CEC), pH, salinity and electrical conductivity (EC) was considered, and their potential influence on the elements' transfer process was evaluated. Statistical analyses, including boxplots, Schoeller diagrams, Robust Principal Component Analysis (RPCA), and Multiple Regression Analysis (MRA), were employed to explore the data. On average, results showed that TF Zn > > TF Cu > TF Cd > TF Co > TF Hg > TF Pb > TF Ni > TF V > TF Se > > TF Tl, with a shared trend for all species despite differences in TF magnitudes observed. In our case, the RPCA allowed the identification of three principal components accounting for 91% of the total variance, and the MRA revealed significant influences of clay content, CEC, and OM on TFs variability, particularly for Zn and Co. The use of the bioavailable fraction of PTEs in the soil to calculate transfer factors provided new insight into the mobility along the food chain of elements, unveiling the general \"propensity\" of some elements to migrate to the biological compartment (e.g., Zn) and the marked resistance of others to be transfered (e.g., Tl).
