This study focused on the total petroleum hydrocarbon (TPH) degradation in phytoremediation of spiked diesel insand. The diesel was added to the sand that was planted with terrestrial plants. Four selected terrestrial plants used werePaspalum vaginatum Sw, Paspalums crobiculatum L. varbispicatum Hack, Eragrotis atrovirens (Desf.) Trin. ex Steud andCayratia trifolia (L.) Domin since all the plants could survive at a hydrocarbon petroleum contaminated site in Malaysia. The samplings were carried out on Day 0, 7, 14, 28, 42 and 72. The analysis of the TPH was conducted by extracting thespiked sand using ultrasonic extraction. The determination of the TPH concentration in the sand was performed usingGC-FID. The degradation of TPH depends on the plant species and time of exposure. The highest percentage degradationby P. vaginatum, P. scrobiculatum, E. atrovirens and C. trifolia were 91.9, 74.0, 68.9 and 62.9%, respectively. In conclusion,the ability to degrade TPH by plants were P. vaginatum>P. scrobiculatum>E. atrovirens>C. trifolia.
