Since early 20th century, heavy metal contamination has increased quickly and it has posed a great danger to the environment is treacherous due to its high toxicity. Phytoremediation has gained popularity recently because of its environment-friendly approach. This study was carried out to assess the phytoremediation potential of Cynodon dactylon for heavy metals from polluted water. The objective of this research was to grow test plant in nutrient solution with different concentrations (50, 100, 150 and 200 µM) of Lead acetate for 20 days. Fresh and dry biomass of vegetative parts (above and below ground) were determined and the Bio-concentration and Translocation factor was calculated. Results revealed that most of the lead from the solution was absorbed by Cynodon dactylon, till the 20th day. Most of the lead was accumulated in the aerial part. The highest lead content was recorded in the above ground part of the plant. This shows that lead has been translocated from the ischolar_main to the above ground part.

Abstract


Since early 20th century, heavy metal contamination has increased quickly and it has posed a great danger to the environment is treacherous due to its high toxicity. Phytoremediation has gained popularity recently because of its environment-friendly approach. This study was carried out to assess the phytoremediation potential of Cynodon dactylon for heavy metals from polluted water. The objective of this research was to grow test plant in nutrient solution with different concentrations (50, 100, 150 and 200 µM) of Lead acetate for 20 days. Fresh and dry biomass of vegetative parts (above and below ground) were determined and the Bio-concentration and Translocation factor was calculated. Results revealed that most of the lead from the solution was absorbed by Cynodon dactylon, till the 20th day. Most of the lead was accumulated in the aerial part. The highest lead content was recorded in the above ground part of the plant. This shows that lead has been translocated from the ischolar_main to the above ground part.
