Study investigates how seven different Central European tree species respond to metal-contaminated soils

For centuries, artisanal and industrial activities have left many soils polluted with excessive levels of heavy metals such as zinc, cadmium, copper and lead, posing a threat to the environment and human health. Cleaning up polluted sites is often difficult and expensive, especially when larger areas are affected. As a result, many sites need to be managed i

The top 3

  1. Leading Plant Genera in Metal Uptake: Hyperaccumulating plants, representing only 0.2% of vascular plant species, include genera like Pycnandra, Noccaea (alpine pennycress), Phyllanthus, and Salix, known for their exceptional ability to absorb various metals.
  2. Trees Best for Lead (Pb) Remediation: Species such as White Poplar (*Populus alba*) and Black Locust (*Robinia pseudoacacia*) are noted for their potential in accumulating lead, making them valuable for phytoremediation efforts in lead-contaminated soils.
  3. Tree Species Most Effective for Cadmium (Cd) Removal: Trees like Chinaberry (*Melia azedarach*), White Poplar (*Populus alba*), and Subabul (*Leucaena leucocephala*) demonstrate significant capacity for cadmium accumulation, making them effective in remediating Cd-contaminated areas.
