Complete removal of TNT in urea-treated soil was accomplished by vetiver at the low initial soil-TNT concentration (40 mg kg−1), masking the effect of urea. Doubling the initial TNT concentration (80 mg kg−1) significantly (p < 0.002) increased TNT removal by vetiver, in the presence of urea. Without vetiver grass, no significant (p = 0.475) change in the soil-TNT concentrations was observed over a period of 48 days, suggesting that natural attenuation of soil TNT could not explain the documented TNT disappearance from soil.||URI:||http://ktisis.cut.ac.cy/handle/10488/4220||ISSN:||0269-7491||DOI:||http://dx.doi.org/10.1016/j.envpol.2009.12.011||Rights:||© Elsevier Ltd.||Type:||Article||Affiliation :||Michigan Technological University
