TL;DRAbstract

We tested the effectiveness of single and repetitive additions of three amendments on trace element stabilisation and volunteer vegetation development in a contaminated soil. The results showed the need of repeated addition depending on the amendment. In the case of inorganic amendments (sugar lime) a single addition was enough to accelerate natural attenuation in soil. However, when organic materials were used solubility of these compounds increased trace element availability with time and new addition were necessary for trace element stabilization
