Overcome the limits of multi-contaminated industrial soils bioremediation: Insights from a multi-disciplinary study.

Phytoremediation can be a promising and sustainable strategy to recovery Potentially Toxic Elements (PTEs) contaminated soils. However, at the field level, this tool can be limited by many issues. Herein, we combined native plant species with different cover type (mono and poly culture) in an in-field mesocosm experiment for the remediation of multi-contaminated soils from Bagnoli brownfield site (Southern Italy).

Investigation and Assessment for an effective approach to the reclamation of Polycyclic Aromatic Hydrocarbon (PAHs) contaminated site: SIN Bagnoli, Italy.

Native plant species were screened for their remediation potential for the removal of Polycyclic Aromatic Hydrocarbons (PAHs) contaminated soil of Bagnoli brownfield site (Southern Italy). Soils at this site contain all of the PAHs congeners at concentration levels well above the contamination threshold limits established by Italian environmental legislation for residential/recreational land use, which represent the remediation target. The concentration of 13 High Molecular Weight Polycyclic Aromatic Hydrocarbons in soil rhizosphere, plants roots and plants leaves was assessed in order to evaluate native plants suitability for a gentle remediation of the study area.

Identification of native-metal tolerant plant species in situ: Environmental implications and functional traits.

A study was undertaken to identify suitable native plants for the phytoremediation of the second largest integrated steelworks in Italy (Bagnoli brownfield site). A phytoecological survey allowed us to identify 139 plant taxa belonging to 58 different families. The most represented families were in the decreasing order Poaceae > Fabaceae > Asteraceae > Apiaceae.
