Calcium nanoparticle-assisted phytostabilisation of toxic metals enhances soil-dependent improvements in the nutritional and safety profile of Amaranthus hybridus.
This study investigated the efficacy of calcium nanoparticles (CaNPs) in mitigating heavy metal (HM) toxicity and enhancing the nutritional quality of Amaranthus hybridus grown in soils from the Osun riverbank (RB) and Ido-Osun dumpsite (DS). Cultivation included control treatments (RB-C, DS-C), foliar application (RB-...
