The present investigation provides data on the performance of Hevea brasilliensis at site clean - up.
Effluent sample from a wetland around abandoned oil - well head in Mgbuoba, a Nigerian Niger Delta
community was characterized and a 43d hydroponic experiment using H. Brasilliensis in the presence of
white light and salted regime, were done to assess its performance at contaminant removal. Deionized
water was used as control and all experiment was done in triplicates. Observed levels of studied heavy
metals (Cd, Pb, and Fe) were statistically significant at p≤0.05 and were reduced by 98 % and 91 %)
respectively for Salted and Unsalted regimes. Salt treatment showed greater root uptake and were up to
58 % (Cd) and 59 % (Pb) compared to the unsalted 42 % and 41 % respectively. Generally, results
indicate excellent levels of phytoextraction of Cd and Pb leaving relatively low or non – detectable
values, thus presenting H. brassilliensis as a possible candidate for phytoremediation of oil-related
contaminated liquid effluent especially a salt – assisted design.
