Post Oil Spill Petroleum Hydrocarbon Components Transport and Evaluation in Parts of the Niger Delta Mangrove Swamp of Nigeria: A Case of Hydrocarbon Component Transport through Non-Turbulent Water
European Journal of Sustainable Development Research, 2021, 5(1), em0152, https://doi.org/10.21601/ejosdr/9708
ABSTRACT: Parts of the Nigerian Niger Delta which also accommodates huge number of oil facilities has swamps in some parts with non – turbulent water bodies. These water bodies are negatively impacted from oil pollution but lack the capacities to self-clean like high flowing waters. The calm nature of these swamps result in higher than normal retention, partitioning and diffusion of hydrocarbon components. This study investigated aliphatic and aromatic hydrocarbon concentrations at different depths for a period of ten months by simulating an oil spill site (8m by 5m and 1.5m deep) typical of a non-turbulent mangrove swamp with suspended sediments and vegetation polluted with 60 litres of crude oil. Impacted water samples were collected at depths of 0.25m, 0.5m, 0.75m and 1.0m. They were filtered and the petroleum aliphatic and aromatic contents analyzed using a GC-FID. The results obtained showed that petroleum hydrocarbons can dissolve and diffuse to different depths at concentrations above safe limits, thus posing great danger to aquatic life and its entire value chain.

Modeling of Vertical Transport of Hydrocarbons of Crude Oil Spills in Non-Convective Water Bodies Supported by Suspended Sediments: Case of Parts of the Nigerian Niger Delta Mangrove Swamps
European Journal of Sustainable Development Research, 2020, 4(4), em0143, https://doi.org/10.29333/ejosdr/9144
ABSTRACT: Crude oil spill is a major source of water pollution. In water with wave and tides, the environment could be self-cleansed. This kind of environment has enjoyed tremendous research attention over the years with plethora of models available for the forecasting, monitoring and management of residual petroleum presence in imparted environments. On the other hand, parts of the Nigerian Niger Delta mangrove swamp contain stagnant water with suspended sediments. The heavy load of suspended sediments has the capacity to adsorb oil and dissolved hydrocarbon components. This paper reports on the development of models for the vertical transport and concentrations of petroleum hydrocarbon components at different strata of the water column by suspended sediments adsorption using governing equations of transport and mass transfer. The developed models were validated with data obtained from simulated stagnant water that was polluted with crude oil.
