The Niger Delta region has witnessed environmental pollution arising from oil activities over the years of oil exploration and production. Soil fertility in both the Lowland Forest Ecological Zone and Island Forest Ecological Zone were investigated to establish the consequences of oil pollution on the soil and remedial actions to restore back quality and fertility of the soil. A suitable cost effective and environmentally friendly technology to handle the pollutions in the Niger Delta region can be found in Remediation by Enhanced Natural Attenuation Process (ENAP) which facilitates the activities of microorganisms to biodegrade the hydrocarbon impacted soil. The study compared the bio-physicochemical parameters of the oil spill polluted soil with particular reference to areas of oil production of the two Ecological Systems with those of the unaffected soil as well as their response to bioremediation interventions using ENAP. The results demonstrated significant decrease in the values of the key indicator parameter, the Total Petroleum Hydrocarbons (TPH). But for the unenhanced process, the result showed low level of reduction of TPH values for the polluted soils. A degradation trend was demonstrated with time leading to significant TPH reductions and improved key soil fertility indices. The result showed that the level of the nutrient status of soil in the region can be improved through the natural attenuation process.

In most field studies, enhancing biodegradation of petroleum hydrocarbons depends on the specific microbial population present. It is a dispute whether inoculation microbial consortium improved the degradation of petroleum because indigenous microorganism can easily adapt to surroundings and contend for inoculation microbial consortium. Therefore, all of three technologies (natural attenuation, biostimulation and bioaugmentation) were evaluated. After 8 weeks of bioremediation, it was observed that bioaugmentation most effectively removed 53% of oil under inoculation condition. Poor oil removal of below 4% was observed under natural attenuation without inoculation. In addition, it was found that the degradation of oil in oil-polluted soil followed second-order model and acquired the dynamics equations. The half-life of natural attenuation, biostimulation and bioaugmentation was 833 days, 75days, 25days, respectively. The results indicated bioaugmentation could improve efficiently the degradation of TPH and shorten the bioremediation period.

Secondary Contamination

Petroleum is an important source of hydrocarbons, which are one of the major environmental contaminants that disturb ecosystem functioning and stability. In the past few decades, a number of approaches employed in the remediation of polluted soil, water, and aquifers have experienced setbacks. Recently, phytoremediation is gaining more attention due to its numerous benefits. Different mechanisms are used in phytoremediation; however, the integration of microorganisms and plant species to achieve remediation has been alluring. Phytoremediation provides a solution to one of the dreadful problems of pollution in situ, devoid of secondary contamination. Phytoremediation addresses pressing environmental pollution problems, and it also provides other important ecosystem services. In this review, a concise discussion of phytoremediation in synergy with microbes will be provided.
