“…Digitaria sanguinalis was observed to have relatively high concentrations of three metals, i.e., Al (4.400 mg/kg), Fe (4.330 mg/kg), and Zn (0.600 mg/kg); similarly, Cynodon dactylon was observed to have relatively high concentrations of two metals, i.e., Mn (34.700 mg/kg) and Ni (11.440 mg/kg) (Appendix A). It has been proven in past too that Digitaria sanguinalis has relatively high bioaccumulation potential for Al, Fe, and Zn [24,25], while Cynodon dactylon has high bioaccumulation potential for Mn and Ni [26][27][28][29]. Since Digitaria ciliaris and Cynodon dactylon are capable of accumulating three (Al, Fe, Zn) or two metals (Mn, Ni) at relatively high concentrations, it is an efficient phytoremediation plant Digitaria sanguinalis was observed to have relatively high concentrations of three metals, i.e., Al (4.400 mg/kg), Fe (4.330 mg/kg), and Zn (0.600 mg/kg); similarly, Cynodon dactylon was observed to have relatively high concentrations of two metals, i.e., Mn (34.700 mg/kg) and Ni (11.440 mg/kg) (Appendix A).…”
