- Abstract
A field experiment investigating the phytoremediation potential of six plant species—Goosegrass (<italic>Eleusine indica</italic>), Bermuda grass (<italic>Cynodon dactylon</italic>), Sessile joyweed (<italic>Alternanthera sessilis</italic>), Benghal dayflower (Commelina benghalensis), Lovanga (<italic>Cleome ciliata</italic>), and Chinese violet (<italic>Asystasia gangetica</italic>)—on soil contaminated with fuel oil (82.5 ml/kg of soil) have been conducted from March to August 2016. The experiments consider three modalities—Tn: unpolluted planted soils, To: unplanted polluted soils, and Tp: polluted planted soil—randomized arranged. Only three (<italic>E</italic>. <italic>indica</italic>, <italic>C</italic>. <italic>dactylon</italic>, and <italic>A</italic>. <italic>sessilis</italic>) of the six species survived while the others died 1 month after the beginning of experimentations. The relative growth indexes showed a strong similarity between the growth parameters of <italic>E</italic>. <italic>indica</italic> and <italic>C</italic>. <italic>dactylon</italic>, each on polluted and control soils, unlike <italic>A</italic>. <italic>sessilis</italic>. Total petroleum hydrocarbons (TPHs) removal efficiency were 82.56, 80.69, and 77% on soil planted with <italic>E</italic>. <italic>indica</italic>, <italic>C</italic>. <italic>dactylon</italic>, and <italic>A</italic>. <italic>sessilis</italic>, respectively; and 57.25% on non-planted soil. According to the bioconcentration and translocation factors, <italic>E</italic>. <italic>indica</italic> and <italic>A</italic>. <italic>sessilis</italic> are involved on rhizodegradation and phytoextraction of hydrocarbons whereas <italic>C</italic>. <italic>dactylon</italic> is only involved into rhizodegradation. Overall, <italic>E</italic>. <italic>indica</italic> and <italic>C</italic>. <italic>dactylon</italic> out-yielded <italic>A</italic>. <italic>sessilis</italic> in the phytoremediation capacity of fuel oil-contaminated soils.
