- •
Co, Cr, Ni, and V total contents in serpentine soils exceed the intervention limits.
- •
Ca/Mg imbalance and low levels of organic matter caused vegetative growth problems.
- •
The highest proportion of heavy metals is bound to least available soil fractions.
- •
TOF-SIMS confirmed association of Co, Ni, Cr and V with Mg silicates and Fe oxides.
- •
There is a risk of heavy metal pollution in areas near serpentinite quarries.
