“…Corrosion of pipelines and tankers, sabotage and oil production operations accounts for 50%, 36% and 6.5% of oil spill incidence in Nigeria [1]. Generally, oil spills is a big threat to the environment in producing region because it can lead to accumulation of toxic substances such as heavy metals into the environment [2,3].…”

This study was aimed at assessing the bioavailability of heavy metals in the surface water of the Middleton river which is a tributary of the river Nun located in the Niger Delta area of Nigeria. Samples were collected at points within and around oil and gas installations in the area while control points were chosen farther from identified pollution point sources. Three replicate samples were collected for each sampling and control location on a biannual basis for two months (March and August 2017) to reflect the dry and wet seasons respectively. A total of forty-two surface water samples were analyzed for heavy metals using standard methods as given in APHA. Heavy metal variables which were examined indicated significant difference between the locations and the two seasons under study (p<0.05). Dry season heavy metals mean were: Fe (6.55 ± 2.36 mg/l and 7.39 ± 1.35 mg/l); Cr (0.43 ± 0.09 mg/l and 0.34 ± 0.02 mg/l); Mn (0.22 ± 0.31 mg/l and 0.02 ± <0.01 mg/l) and Zn (0.04 ± 0.03 mg/l and 0.01 ± <0.01 mg/l) representing five sampling and two control locations respectively. Wet season heavy metal mean levels were relatively lower when compared to the dry season and depicted values of Fe (4.91 ± 2.55 mg/l and 5.46 ± 2.09 mg/l); Cr (0.27 ± 0.05 mg/l and 0.23 ± 0.01 mg/l); Mn (0.13 ± 0.25 mg/l and <0.01 ± <0.01 mg/l) and Zn (0.01 ± 0.01 mg/l and <0.01 ± <0.01 mg/l) across five sampling and two control locations respectively. All other heavy metals analyzed such as Cd, Ni, Co, Pb, and Cu was found to be below the detection limit of the GBC Avanta PM A6600 -Flame Atomic Absorption Spectrophotometer. The iron and chromium levels found in the Middleton river exceeded permissible limits of DPR, FME, WHO and NESREA while chromium and zinc were within permissible limits of regulatory stipulations. Lower concentration of heavy metals in the wet season could be due to dilution effects while the absence of undetected heavy metals may depict that activities leaching out this heavy metals are not common in the study area.

“…According to Iniaghe et al (2013), Nwilo and Badejo (2005), about 50%, 28%, 21% and 1% of oil spills are due to corrosion, sabotage, oil production and mechanical problems (including failure of engineering drills and machines, inability to effectively control oil well, and inadequate care in loading and unloading of oil vessels) respectively. Similarly, Adelana et al (2011) reported that corrosion of pipelines and tankers, sabotage and oil production operations accounts for 50%, 36% and 6.5% oil spill incidence in Nigeria.…”

“…For instance, in 1999 Jesse community of Delta State (Ambe et al, 2015), Nembe/Brass in Bayelsa state and several others in the Niger Delta region, experienced the loss of lives due to fires from spill. In extension, Nigeria's oil line explosion killed over 200 people in Lagos state (Adelana et al, 2011).…”

The Niger Delta region of Nigeria is one of the largest wetland and biodiversity hotspots in Africa that inhabit several endemic species. Biodiversity including plants, animals and microbes have several economic importance to human and its ecosystem. Of recent, the intensity of bush burning in the Niger Delta has increased. Bush burning is among the leading cause of decline in composition and abundance of biodiversity. This study evaluated the potential causes of bush burning, impacts on biodiversity and possible options for mitigation in the Niger Delta region of Nigeria. The study found that quest for bush meat (i.e. major source of animal protein), burning of solid wastes, precarious discharge of cigarette remains and deliberate uncontrolled in-situ burning by farmers as the leading cause of bush burning. Bush burning portends adverse effects like; habitat fragmentation, destruction of medicinal plant, extinction of species in the wild, loss of food sources, loss of raw material that can be useful for several art work, wood fuel, construction and shelter materials, and disruption of ecological processes including biogeochemical cycling. The paper concludes by suggesting pasture management, wastes management, sensitization, enactment and implementation of bush burning laws and specifying punishment for offenders, and introduction of biodiversity conservation techniques in school curriculum as potential option for mitigation.

“…In-situ bioremediation is carried out at the site of interest whereas in ex-situ bioremediation, the contaminated soil is collected and processed at an offsite area such as a laboratory for cleansing [2]. The main procedure frequently used in oil-spill bioremediation technique is biostimulation, that is, through the addition of nutrients (nitrogen, phosphorus, and potassium) and regulation of environmental conditions to maximize growth of native bacteria and biological degradation.…”

This study identifies total petroleum hydrocarbons (TPH) and traces of heavy metals such as zinc, lead, cadmium, nickel, and copper in crude oil-contaminated soil. It also focuses on the use of poultry manure and sorghum husk in the bioremediation of the contaminated soil. Crude oil-contaminated soil sample was divided into five parts (A: untreated, B: poultry manure, C and D: poultry manure and sorghum husk in ratios 1:1 and 3:1, respectively, and E: sorghum husk). The heavy metals concentrations and TPH content were assessed initially in the untreated soil sample and later on the 5th, 10th, 15th, 20th, 25th, and 30th days after adding the stimulants. Gas chromatographymass spectroscopy (GC-MS), atomic absorption spectrometer (AAS), pH and conductivity meters were used for TPH, heavy metals, pH and electrical conductivity analyses, respectively. The results showed soil sample C to have highest TPH reduction, while the soil sample E exhibited 96.1% reduction in nickel, 97.5% reduction in zinc, 100% reduction in lead, and 99.3% reduction in copper. The pH of the soil ranged from 7.13 to 7.92 (within the range 6.5-8 suitable for microbial growth). The electrical conductivity for soil samples B-E increased and also in the acceptable range of 130-2320 μS/cm.
