Characterization of soil sampling sites in areas contaminated with heavy metals after the use of the rehabilitation systems [S1 (Ec-R and Ec-IR) and S2 (EcB-R and EcB-IR)], in non-rehabilitated contaminated area (NR,) and in non-contaminated areas [Cerrado (C) and Pasture (P)].

Areas – soil vegetation cover at the sampling time	Sampling sites
1 – S1 Area planted with Eucalyptus camaldulensis in rows and with spontaneous vegetation between rows of E. camaldulensis. Anthropized soil.	Ec-R	Row
	Ec-IR	Inter-row
2 – S2 Area with E. camaldulensis plantation in rows and complete cover by Brachiaria decumbens (sown) between the rows of E. camaldulensis plantation. Anthropized soil.	EcB-R	Row
	EcB-IR	Inter-row
3 – Non-rehabilitated contaminated area- Area of waste disposal with high soil contamination and without vegetation cover. Anthropized soil.	NR
4 – Original Cerrado – Cerrado vegetation with regional typical species. Latosols typical cerrado.	C
5 – Pasture- Brachiaria decumbens grass planted in Latosols typical cerrado.	P
