A study of celery employed as a PAHs phytoremediator examined the soil enzyme activity, PAHs-degrading microorganisms, and PAHs speciation in soil. Results showed that celery could enhance PAHs remediation significantly compared with the control after 90 days, with removal efficiencies of 31.29% in soil, 30.79% in non-rhizosphere soil, and 50.21% in rhizosphere soil. Soil enzyme activity and PAHs-degrading microorganisms increased in rhizosphere soil compared with non-rhizosphere soil. PAHs concentration in the edible portion of celery was only 17.13 1.24 µg/kg, and bioconcentration factors in the aboveground part of celery were only 0.025. This study provides an indication of potential practical utility for celery in farmland soil phytoremediation.
