Heavy metals accumulation and distribution pattern in different vegetable crops

  Different vegetable crops grown on heavy metal contaminated soil showed marked difference in metal accumulation, their uptake and distribution pattern. Crop species also showed remarkable difference in metal concentration of various plant parts. Based on metal accumulation in edible parts and whole plants, root vegetables namely, radish and carrot registered lower accumulation of almost all heavy metals...

Utilization of Blighia sapida (Akee apple) pod in the removal of lead, cadmium and cobalt ions from aqueous solution

  Blighia sapida pod was utilized as a low cost adsorbent to remove Pb(II), Cd(II) and Co(II) ions from aqueous solutions. The effect of pH, contact time, initial metal ion concentration, and adsorbent dosage were evaluated using batch adsorption experiment at 32°C. pH dependence study of the biosorption process revealed that maximum pH for Pb(II), Cd(II) and Co(II) ions removal from aqueous solution...

Potentials of Synedrella nodiflora and Sida fallax growing naturally around an abandoned railway station for phytoextraction of heavy metals

  Phytoextraction is a non-destructive, cost-effective and safe alternative to conventional cleanup techniques of contaminated soils. In this study, the ability of two plants species Synedrella nodiflora and Sida fallaxgrowing naturally around the abandoned Asafo Railway Station in Kumasi for selective extraction and accumulation of four heavy metals (Pb, Cu, Fe and Zn) were studied using Atomic...
