Phytoremediation of Wastewater From Oil Well Drilling: Potential of Different Plant Species

Water Environment Research, Volume 98, Issue 5, May 2026.
Purple fountain grass (Cenchrus setaceus “Rubrum”) is a promising plant for using in constructed wetlands treating complex oil drilling effluents. ABSTRACT This study evaluated the removal of contaminants present in wastewater from oil well drilling in the presence of three plant species: water hyacinth (Eichhornia crassipes), cattail (Typha ...

Metarhizium anisopliae Mitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

Advanced Science, Volume 13, Issue 21, 13 April 2026.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...
