Abstract

Remediation technology is a promising technique that decreases pollutants like hydrocarbons from the environment. An experimental work was done at green house of University of Technology in order to study the effect of crude oil on the plant growth and to measure the decrement which happened on shoot height, germination rate and the reduction of total petroleum hydrocarbon (TPH), which resulted by this phytoremediation technique. The samples of soil were measured for TPH reduction and removal by Horiba model OCMA - 350. Five doses were used in this experiment (0 control, 10x103, 30 x103, 50 x103, 75 x103) (mg crude oil / kg soil) or (ppm). The greater efficiency was obtained in the treatment 50 x103 ppm seeded with cotton, in which cotton removed 50.66% of the primary TPHs from soil. Results showed that the employed vegetate species were promising and effective in reducing and removing TPHs from freshly polluted soil.

Highlights

Pollution that had been found in the used agricultural lands is serious trouble contributed by the processing and allocation of crude oil and refined petroleum output in many oil producing countries [1]
A promising behavior is shown by the vegetated species that was employed in this phytoremediation research in removing petroleum hydrocarboncontaminated soil
The collected water from the pans was put in the irrigation to avoid the loss of the petroleum crude oil

Summary

Introduction

Pollution that had been found in the used agricultural lands is serious trouble contributed by the processing and allocation of crude oil and refined petroleum output in many oil producing countries [1]. As these problems are becoming bigger day by day, the solution must be found to clean up the pollution and this has led to exploration of many remedial approaches including physical and chemical methods to reduce the pollution. One of the most effective techniques in the biodegradation is phytoremediation where it employed vegetates and microbes for the remediation of contaminated sites. Many vegetates were studied to know if they have phytoremediation potential to remove and decrease petroleum contaminants from soil [5],[6],[7]
