Phytoremediation of Crude Oil Polluted Water by Pistia stratiotes L.
Ochekwu Edache Bernard and Ezekwe Thadeus Chukwuemeka

Background and Objective: The exploration and exploitation of crude oil in the Niger Delta has led to the pollution of water bodies in this area of Nigeria. This study was carried out to determine the phytoremediation potential of aquatic macrophyte in a crude oil polluted aquatic habitat. Pistia stratiotes (water lettuce) was used as a phytoremediating aquatic macrophyte to evaluate its remediating potential on crude oil polluted water. Materials and Methods: Four different levels of pollutions of 0, 50, 100 and 150 mL were polluted in a 20 L of water and these pollutions were replicated 5 times. Physiochemical parameters as temperature, conductivity, total dissolved solid (TDS), dissolved oxygen (DO), salinity, turbidity, pH, total hydrocarbon content (THC) were analyzed. Also, heavy metals Cu, Zn, Cd and Pb were analyzed in the water and plant samples. Results: Statistical (p<0.05) analysis reveals that Pistia stratiotes despite its low level of tolerance and negative response to high doses of crude oil pollution reduced the THC of water and heavy metals in a negligible amount which are non-significantly (p<0.05) different except for Pb which is significantly (p<0.05) lower than other heavy metals (Cu, Zn and Cd). Conclusion: Results from this experiment shows that the aquatic weed Pistia stratiotes has potential for phytoextraction and rhizofiltration which are forms of phytoremediation.
