Abstract: 

SOILS WERE COLLECTED FROM AHVAZ DESALTING UNIT NO.2 AT THE DEPTH OF 0-30 CM, AND THEN POLLUTED WITH 1% W/W OF CRUDE OIL, INCLUDING ASEMARI AND BANGESTAN CRUDE OIL. POTS EXPERIMENT WAS PREPARED WITH THREE REPLICATES, AND RHIZOSPHERE MICROBIAL NUMBER, PLANT BIOMASS, AND RESIDUAL TPHS WERE DETERMINED. TPHS AND HETEROTROPHIC BACTERIAL NUMBER WERE MEASURED BY GC AND HPC METHOD RESPECTIVELY. DATA WERE ANALYZED USING THE SOFTWARE STATISTICAL PACKAGE FOR SOCIAL SCIENCES [SPSS 17 FOR WINDOWS] AND EXCEL.
RESULTS SHOWED THAT THE MEAN OF TPH REMOVAL PERCENTAGE IN PLANTED SOIL [38.45%] WAS HIGHER THAN THAT IN UNPLANTED SOIL [16.67%]. ALSO, THE MEAN OF TPH REMOVAL PERCENTAGE IN TREATMENTS THAT RECEIVED NUTRIENT WAS HIGHER THAN IT IN FREE NUTRIENT TREATMENTS. ALTHOUGH HIGH CLAY AND SALINITY OF THE EXPERIMENTAL SOIL HAVE A PROHIBITIVE EFFECT ON THE PHYTOREMEDIATION EFFICIENCY, BUT RESULTS SHOW THAT THE PLANT IMPROVE TPH DEGRADATION DURING PHYTOREMEDIATION; MOREOVER, RESULTS SHOW THAT ADDITION OF NUTRIENT INCREASE TPH REMOVAL.
