“…Petroleum hydrocarbon contamination of soils and sediment is a global concern because of the toxicity [16] and refractory character of the aromatic components in the absence of oxygen [17]. PAHs, which make up about 5% by volume, are a widespread class of environmental chemical contaminants of anthropogenic or natural origin (Block et al, 1991).Although predominant oil pollution in the United Kingdom contains high volumes of aliphatic hydrocarbons [18], petroleum pollution in the tropical region like the Nigeria's Niger Delta contains complex mixtures of both the aliphatic and aromatic hydrocarbons [19,20].…”

Petroleum exploration and production in the Nigeria's Niger Delta region and export of oil and gas resources by the petroleum sector has substantially improved the nation's economy over the past five decades. However, activities associated with petroleum exploration, development and production operations have local detrimental and significant impacts on the atmosphere, soils and sediments, surface and groundwater, marine environment and terrestrial ecosystems in the Niger Delta. Discharges of petroleum hydrocarbon and petroleumderived waste streams have caused environmental pollution, adverse human health effects, socioeconomic problems and degradation of host communities in the 9 oil-producing states in the Niger Delta region. Many approaches have been developed for the management of environmental impacts of petroleum production-related activities and several environmental laws have been institutionalized to regulate the Nigerian petroleum industry. However, the existing statutory laws and regulations for environmental protection appear to be grossly inadequate and some of the multinational oil companies operating in the Niger Delta region have failed to adopt sustainable practices to prevent environmental pollution. This review examines the implications of multinational oil companies operations and further highlights some of the past and present environmental issues associated with petroleum exploitation and production in the Nigeria's Niger Delta. Although effective understanding of petroleum production and associated environmental degradation is importance for developing management strategies, there is a need for more multidisciplinary approaches for sustainable risk mitigation and effective environmental protection of the oilproducing host communities in the Niger Delta.

“…In HMA plant A, the pristane/phytane ratios of subsurface samples 10 and 20 m in the dry season and 10 m in the rainy season were higher than unity. This suggests a mixture of oil and terrestrial plant materials which may be attributed to the decayed vegetation in the subsurface soils since the vicinity has been previously used as farmstead (Osuji and Achugasim, 2007). Isoprenoids (pristane and phytane) were not detected in samples from distances beyond 30 m in HMA Plant A during the dry season.…”

This study investigated the occurrence and sources of aliphatic hydrocarbons (AHCs) in soils within the vicinity of hot mix asphalt (HMA) plants. Soil samples were collected from two HMA plants and analysed with gas chromatography -flame ionisation detector (GC-FID). Sample collection was from both surface (0-15 cm) and subsurface (15-30 cm) soils at an increasing distance of 10 m from the HMA plants while the control samples at both depths were collected at 1 km away from the plants. The AHCs concentration (nC9-nC38) in soils from both HMA Plants ranged from 8.16 -433.04 mg/kg and 5.91-177.83 mg/kg for surface and subsurface soils respectively while the concentration in the control samples ranged from 5.97 -23.95 mg/kg and 2.52 -13.31 for surface and subsurface soil respectively. The sources of the AHCs were determined using isoprenoid ratios, carbon preference index (CPI) and maximum carbon chain (Cmax). The isoprenoid ratios and CPI values of the samples closer (< 20 m) to the HMA plants were < 1 and < 2 respectively indicating anthropogenic inputs. Samples > 20 m from the HMA plants showed mixture of both anthropogenic and biogenic sources. ©JASEM http://dx.doi.org/10.4314/jasem.v20i4.24
