Evaluating Populus tremula L. and Salix caprea L. for phytoremediation: growth, metal uptake, and biochemical responses under arsenic, cadmium, and lead stress

Frontiers in Plant Science
This study investigates the phytoremediation potential of Populus tremula L. and Salix caprea L. in response to As, Cd, and Pb exposure using hydroponics. Seedlings were exposed to 5–50 µM Cd, 100–1000 µM As, and 50–200 µM Pb in P.
