Effectiveness of Vetiver Grass (Vetiveria Zizanioides L. Nash) for phytoremediation of endosulfan in two cotton soils from Burkina Faso

Abstract : The influence of vetiver grass (Vetiveria zizanioides) on the fate of endosulfan was studied using a vertisol and a lixisol soils from cotton-growing areas of Burkina Faso. Endosulfan adsorption isotherms were prepared for planted and unplanted soils. Pot experiments were then conducted for six months. For both soils, endosulfan adsorption was higher on planted soils (K-f= 6.53-9.73mg(1-n)L(n)kg(-1)) than on unplanted soils (6.27-7.24mg(1-n)L(n)kg(-1)). In unplanted soils, vertisol adsorbed more endosulfan than lixisol. From the pot experiments, the estimated half-lives of endosulfan in unplanted soils (40.6 to 43.1days) were higher than in planted soils (34.5 to 40.6days) containing a greater number of endosulfan-degrading microorganisms. Six months after treatment, endosulfan was not detected in soils. The effectiveness of vetiver in promoting adsorption and the disappearance of endosulfan in both studied soils should be validated on the cotton plot scale in Burkina Faso.
