Crude oil pollution of water bodies is a worldwide problem that affects water ecosystems and is detrimental to human health and the diversity of living organisms. The objective of this study was to assess the ability of water hyacinth (Eichhornia crassipes (Mart.) Solms) combined with the presence of magnetic nanoparticles capped with natural products based on Myrrh to treat fresh water contaminated by crude petroleum oil. Magnetic nanoparticles based on magnetite capped with Myrrh extracts were prepared, characterized, and used to adsorb heavy components of the crude oil. The hydrophobic hexane and ether Myrrh extracts were isolated and used as capping for magnetite nanoparticles. The chemical structures, morphologies, particle sizes, and magnetic characteristics of the magnetic nanoparticles were investigated. The adsorption efficiencies of the magnetic nanoparticles show a greater efficiency to adsorb more than 95% of the heavy crude oil components. Offsets of Water hyacinth were raised in bowls containing Nile River fresh water under open greenhouse conditions, and subjected to varying crude oil contamination treatments of 0.5, 1, 2, 3, and 5 mL/L for one month. Plants were harvested and separated into shoots and roots, oven dried at 65 °C, and grounded into powder for further analysis of sulphur and total aromatic and saturated hydrocarbons, as well as individual aromatic constituents. The pigments of chlorophylls and carotenoids were measured spectrophotometrically in fresh plant leaves. The results indicated that the bioaccumulation of sulphur in plant tissues increased with the increased level of oil contamination. Water analysis showed significant reduction in polyaromatic hydrocarbons. The increase of crude oil contamination resulted in a decrease of chlorophylls and carotenoid content of the plant tissues. The results indicate that the water hyacinth can be used for remediation of water slightly polluted by crude petroleum oil. The presence of magnetite nanoparticles capped with Myrrh resources improved the remediation of water highly polluted by petroleum crude oil.

Mathematical modelling of in situ (on site) bioremediation of crude petroleum polluted soil was investigated. An unsteady state mathematical model based on bulk flow of oil through the soil and molecular diffusion through the pores of the soil was developed. The parabolic partial differential equation developed was resolved into a system of ordinary differential equations (ODEs) by orthogonal collocation method and the necessary boundary condition was used. The resultant system of ODE was solved using fourth-order Runge-Kutta method. The simulated data gave a good agreement with experimental data.

ABSTRACT The present study consists of assessing the effects of Abura heavy crude petroleum oil (AC) and Oredo light crude petroleum oil (OC) on the survival of Paspalum vaginatum. The effectiveness of two dispersants, Goldcrew and Corexit 9527, in removing oil from P. vaginatum previously sprayed with either Abura of Oredo crude petroleum oil was assessed, the effect of time of dispersant application following crude oil pollution on growth and survival of P. vaginatum was also studied. Plants treated with AC recovered after 8 days while 100% mortality was recorded for plants treated with OC + Corexit 9527 (O24C0 and O48C0). Corexit 9527 was not effective in ameliorating the lethal effects of Oredo crude oil. Although, P. vaginatum recovery was apparent 70 days after AC pollution and after cleaning with Goldcrew (A24GCand A48GC), both treatments resulted in significant (P <0.05) lower biomass and stem density compared to control. It is concluded that plants cleaned with Goldcrew dispersant after 24 h recovered faster than those cleaned after 48 h. Exposure of P. vaginatum to light crude oil or light crude oil + Corexit 9527 is detrimental and can inhibit growth where as it will recover when exposed to heavy crude oil or heavy crude oil + Goldcrew.
