“…The (Gundlach, 2018;Little et al, 2018;Bonte et al, 2019). Prior the oil pollution saga, the creek and mangroves are known to provide nutrient filtration, fish nursery, bird staging areas and local transport corridors for human access to vital natural resources such as food and wood for building, fuel and making of cultural artifacts (Fentiman & Zabbey, 2015).…”

“…making the water unfit for domestic use. Little et al (2018) measured total aliphatic and aromatic hydrocarbon concentrations in sediments and reported high contamination of TPHs, aliphatic and aromatic hydrocarbons in the equivalent C12-C44 range (EC12-EC44) in surface and subsurface sediments. Bonte et al (2019) found high levels of TPHs in sediments from Bodo Creek at depth 2-4 m, and reported that majority of petroleum hydrocarbons are restrict to depths <50 cm.…”

Chemical-surveys of sediments are source of information about historical-pollution in aquatic-ecosystems, because ecological/human-health risks may arise from polycyclic-aromatic-hydrocarbons (PAHs) and nitrogen-PAHs presence in aquatic-environments, particularly sediments, where they partition. Despite this, sediment-PAHs/N-PAHs have not been reported in the Niger Delta. This study investigated vertical-profiles of PAHs/N-PAHs in 2cm-intervals-segments from Bonny Estuary, Niger Delta. Analysis showed that ƩPAHs/ƩN-PAHs in segments ranged from 8699-22528µg/kg and 503-2020µg/kg, respectively. Abundant-PAH/N-PAH are 2,6dimethyl-naphthalene and benzo[a]acridine. PAHs/N-PAHs in the samples appeared to be from petrogenic and pyrogenic-sources. Petrogenic-PAHs/N-PAHs were predominated by 2-, 3-rings, alkylated-substituents, while, pyrogenic-PAHs/N-PAHs were dominated by 4-, 5-, 6-rings. Surface-sediments were dominated by petrogenic-PAHs/N-PAHs while, deeper-cores were heavily-contaminated with pyrogenic-PAHs/N-PAHs. ƩPAHs exceeded the ISQGs and PELs of CSQGs. Ʃ-quinoline/Ʃ-acridine exceeded the guidelines for protection of aquatic-life. Furthermore, there are concerns over toxic-ratios >70% in the estuary. Such surveys may be helpful in future sediment-management-decisions for contaminated-systems and long-term-monitoring of sediments to assess remediation/recovery.

“…If polluted sediments are not properly cleaned, they can be perennial sources of pollution, releasing hydrocarbons whenever they are disturbed. Lightweight oil components evaporate easily, whereas the majority of the heavy fractions, rich in carcinogenic compounds like aliphatic, aromatic, and PAHs usually persist for long in sediments polluted with oil (Little et al., 2018).…”

“…After assessing the contaminated sediments in the Bodo community of Niger Delta, Little et al. (2018) recommended that the heavily contaminated surface sediment layer (0–5 cm) should be physically removed and treated ex situ. The agitation of the top sediment layer could also stimulate the evapotranspiration of volatile organics.…”

Crude oil is the major source of income to the Nigerian economy, which accounts for about 70% of government revenue and more than 83% of the country's total export earnings. Crude oil spills are frequent events in Nigeria and in the past 50 years, it is estimated that 10-13 million tons of oil have been spilled into the environment and more than 77% of it have not been recovered. The spills are caused by sabotage, oil exploration activities, equipment failure, pipeline corrosion, and tanker accidents. In most cases, simple and cheap remediation methods are employed which do not adequately consider the complexity of the different polluted media. This study reviewed the different remediation technologies for polluted water, soil, and sediment media that are appropriate for the local Nigerian environmental conditions. The characteristics of the Nigerian crude oil have been discussed, and the basic factors to be considered in cleaning crude oil contamination were explored. Both full-scale and pilot-scale case studies were reviewed. Biostimulation was identified to have a high potential for cleaning polluted sediments in the Niger Delta, while ex-situ trenching and treatment are recommended for groundwater treatment and bioremediation is recommended for contaminated soils. The limitations of the methods/techniques are discussed, and the future technological prospects are highlighted in this review.
