Heavy metals,

The accumulation of metals in different environmental compartments poses a risk to both the environment, human and biota health. The combination of both Phyto and nano remediation techniques have been gaining more attention in this regard. This technique leverage on the unique and specific absorption qualities of plant roots, and employs these inherent processes with the bioaccumulation, translocation, and pollutant degrading capacities of the whole plant as well as cost effectiveness, and potential to treat a broad range of contaminants.

Industrial processes, including scrap yards, can contaminate surface waters with heavy metals, posing a risk to aquatic habitat and human health. Thus, the concentrations, ecological and health risks of heavy metals in surface water and sediment of the Ogun River in Lagos was investigated. Surface water and sediments collected from the Ogun River were analyzed for some physicochemical parameters and heavy metals using standard procedures.
