  Post-remediation assessment of residual total petroleum hydrocarbon (TPH) in an aged crude oil-contaminated soil (ACOCS) in Ogoni after seventy-day enhanced remediation by bio stimulation was investigated using gas chromatographic fingerprinting technique and phytotoxicity bioassay. Seven treatments were designed and composted water hyacinth (EC), Mexican sunflower (TD) and Bermuda grass (CD) was applied as bio stimulants. EC, TD and CD (2,500g each) were used to bio stimulate 4,000 g of ACOCS in situ in TPA (treatment plot A) through TPG. The treatments were monitored for a period of seventy days and the rate of crude oil biodegradation analyzed. Gas chromatographic fingerprints of crude oil in the soil showed the absence of n-C1 to n-C8 carbon length and could be attributed to weathering processes. Carbon lengths between n-C9 to n-C34 were significantly .. View More»
