Zusammenfassung

Acidity, nutrient availability and potential toxicity in the coal mine dump of As Pontes (NW Spain) are evaluated. Then, cationic exchange capacity, actual and potenctial acidity and available heavy metals (DPTA extracted) are analized. Results show a wide variability of the spoil materials. Sulfur level in the spoils explains the different actual and potential acidity conditions. Cationic exchange capacity is low (< 10 cmol (+) Kg-1), but is similar to the contiguous natural solis DPTA-extracte metals display folow sequence: Fe >> Mn >> Cu > Ni ≥ Zn ≥ Pb > Co >> Cd and the system acidity explains its mobilization.
