abstract={Environmental pollution by petroleum is an increasing global problem with phytoremediation being one of the viable tools for cleansing crude oil polluted soil. The aim of this study was to ascertain the remediating effect of <i>Piper</i> <i>guineense</i> and <i>Azadirachta</i> <i>indica</i> on the levels of polycyclic aromatic hydrocarbons (PAH) on the leaves of deliberately crude oil polluted germinating <i>Telfairia occidentalis</i>. Vessel I contains growing plant and water only, vessel II contains growing plant + crude oil only, vessel III, IV and V had growing plant+crude oil + 100g of <i>Azadirachta indica</i>, 77g of <i>P. guineense</i> and 100g of <i>Azadirachta indica</i> +77g of <i>P. guineense</i> leaves respectively. After 8weeks of plant growth, the levels of polyaromatic hydrocarbons (PAH) in the plants were determined using gas chromatography. The result indicates that naphthalene levels were significantly higher (p&lt;0.05) in plants grown on vessels with 77 g <i>P. guineense</i> (4.2 ¡À 0.003 ¦Ìg/Kg) and 77 g <i>P. guineense</i> + 100 g <i>A. indica</i> (4.2 ¡À 0.007 ¦Ìg/Kg) compared to the crude oil only vessel (2.1 ¡À 0.003 ¦Ìg/Kg). Phenanthrene levels were significantly lower (p&lt;0.05) in plants grown on vessels with 100 g <i>A. indica</i> (1.7 ¡À 0.002 ¦Ìg/Kg) compared to levels in crude oil only grown plants (2.2 ¡À 0.003 ¦Ìg/Kg). Acenaphthylene, acenaphthene, fluorene benzo(k)fluoranthene and benzo(a)pyrene levels were significantly higher (p&lt;0.05) in plants grown in vessels III,IV and V compared to the crude oil only vessel. Also, dibenzo(a,b)anthracene and indenol(1,2,3cd)pyrene levels were significantly lower (p&lt;0.05) in plants grown on vessels remediated with 100 g <i>A. indica</i> and 77 g <i>P. guineense</i> + 100 g <i>A. indica</i> when compared with plants grown in crude oil only vessel. Therefore, it could be concluded that <i>P. guineense</i> and <i>A. indica</i> leaves could be good for phytoremediation of phenanthrene, benzo(b)fluoranthene, dibenzo(a,b)anthracene and indeno(1,2,3cd)pyrene.},
