Lanthanum ions intervened in enzymatic production and elimination of reactive oxygen species in leaves of rice seedlings under cadmium stress
Rare earth elements (REEs) at proper concentrations were observed to alleviate heavy metal stress. However, the potential mechanisms are not clear. Thus, the present work focused on the mechanisms of lanthanum (La) ions on the generation and elimination of reactive oxygen species (ROS) production in leaves of rice seedlings hydroponically cultivated in 30 µM cadmium chloride (CdCl2) for two ...

Antioxidant and prooxidant effects of lanthanum ions on Vicia faba L. seedlings under cadmium stress, suggesting ecological risk
The present study combined chemical analyses and biological measurements to investigate biphasic effects of La on Cd stress in leaves of Vicia faba seedlings, which were hydroponically cultivated for 15 d in the combination of 6 µM CdCl2 and 2 to 480 µM La(NO3)3, respectively. The results showed that contents of Cd first elevated above and then declined below the 6 µM single Cd treatment when 2 ...

Uptake and translocation of lead and pyrene by ryegrass cultivated in aged spiked soil
A greenhouse study was conducted to investigate the uptake and translocation of lead and pyrene in ryegrass (Lolium multiflorum L), cultivated in spiked soil. After ageing, the pots were cultivated with ryegrass seedlings to investigate soil-to-plant transfer characteristics of lead and pyrene. In the spiked soils, the biomass of plants was not significantly lower in comparison with the control, ...
