“…The hydrocarbons are less dense than water, and tend to float and not penetrate the lower strata. Also, the hydrocarbons are mainly absorbed in the organic matter which has a polarity more similar to the hydrocarbons than to water or soil minerals; organic material is highly accumulated in the surface due to primary production of vegetable material (Cram et al, 2004). Of the samples an alyzed, in 23 of the 60 samplin g points, hydrocarbons were not found, or only in very low concentrations (range: 0 -1,600 mg/Kg, dry weight; average 700 mg/Kg).…”

“…The alternative use of land, ecological restoration and cattle pasture production in old crude oil spills sites, as well as mining residues and pesticide affected areas ar e n ecessar y and cur r en tly represent a social concern leading to litigation or agreements (Carvalho et al, 2002;Razo et al, 2006). It requires the inclusion of ecotoxicological assays, risk based criteria (Cram et al, 2004;Zavala-Cruz et al, 2005) and remote-sensing technology (Wang and Ding, 2000) during site characterization and diagnostic studies. Furthermore, the detailed analysis of soil geomorphology and flood patterns are relevant data for the development of remediation projects and for decision making by the authorities responsible (Iturbe et al, 2004;Osuji and Opiah, 2007).…”

“…In this sense, several soil characterization and diagnostic studies have been carried out in crude oil contaminated sites in this region. Cram et al, (2004) evaluated the mobility and content of PAH in sites with different spill histories and flooded conditions. They pointed out that the persistence of some PAH (polycyclic aromatic hydrocarbon) is due to limited microbial activity mostly where anaerobic conditions prevail and also to the low hydrocarbon availability to microorganisms (Okafor and Opuene, 2007;Opuene et al, 2007).…”

ABSTRACT:A site evaluation was made for a low-lying property in an old river levee/marsh association, used marginally for cattle raising, which was contaminated due to historical practices. Contamination was related to geomorphology: the lowest areas contained 79 % of the contaminated samples. Other contaminated samples were all rear access roads (probable intentional dumping). There were no samples in the higher, levee areas away from roads with hydrocarbon concentrations above 3,000 mg/kg. Medium and high impact levels, corresponding to average hydrocarbon concentrations of 13,400 mg/kg and 109,700 mg/kg, respectively, were found in 28 % and 27 % of the property area. The medium impact level was predicted to have a reduced pasture production potential of ~ 50 % while at the high impact level practically no pasture production was predicted. Toxicological risk to cattle is present in only 12 % of the sample points although almost all of these are in very marshy areas not apt for cattle raising. Because the hydrocarbons at this tropical site are very weathered, acute toxicity was not related to hydrocarbon concentration. Although slightly more than half of the property has hydrocarbon concentrations above the permissible limit, only about one-third of the contaminated area is apt for cattle raising. This study, based on hydrocarbon distribution related to site geomorphology, soil toxicity bioassay, risk assessment to cattle and evaluation of pasture production allowed to made a more accurate assessment and definition of future use of the site. These criteria could be used for diagnostic studies of sites with similar tropical conditions.

In Tabasco the petroleum industry pollutes soil recurrently by oil spills. We analysed Pb, V, Ni and Cr concentrations in water samples, and total metal contents and metal fractions in soil samples of contaminated and non-contaminated soils and in sediments. Besides, we determined Eh, pH, DOC and major ions in water and Eh, pH, C org in soils and sediments. Sediments contained considerably larger heavy metal (HM) concentrations than soils. Local background concentrations of V, Ni and Cr in soils are larger than global means and oil spillages have not added these metals in quantities that exceed the natural variation. Spillage of formation water increases Pb concentrations in soils, particularly in mobile fractions. The contribution of the oil industry to HM loads is diluted by large fluvial water and sediment discharges and difficult to assess by comparison of total metal contents. Therefore, easily mobile metal fractions are much better indicators.

“…Crude oil is a complex mixture of many chemical compounds, composed primarily of phenol and aromatic hydrocarbons including polycyclic aromatic hydrocarbons (PAHs) many of which are of toxicological interest (King, 1988;MacFarland, 1988;Cram et al, 2004). The PAHs can originate from both anthropogenic sources (such as coal gasification, accidental oil spills, as well as natural processes such as fossil fuel and wood combustion) and biogenic sources (with biogenic precursors like terpenes, pigments, and steroids) into the environment (Gevao, 1998;Asikainen et al, 2002;Law et al, 2002;Koh et al, 2004;Takasuga et al, 2007;.…”

The cumulative effects of small accidental spills in the marine environment can have significant impacts on marine wildlife. Aquatic fauna are often examined for evidence of hydrocarbon exposure, as it may pose direct threat to their health and consequently humans. The composition and spatial distribution of hydrocarbons especially polycyclic aromatic hydrocarbons (PAHs) were investigated in the tissue of periwinkles Littorina littorea from two carefully selected locations within the oil-polluted coastal area of Ondo State, Nigeria using gas chromatography with flame ionization detector and mass spectrometry (GC/FID/MS). The tissues were sampled and analyzed to evaluate the spatial extent and persistence of pollution, as well as their potential for adverse effects. Complex series of compounds, many of which were considered biotransformed products were obtained. The PAHs ranged; not detectable (nd) -56.23 µg/g dry weight (dw) and nd -79.43 µg/g dw during the dry and wet seasons respectively. The total PAHs (∑PAHs) during the wet season was almost 100% greater than ∑PAHs during the dry season; a factor attributed to run-off from contaminated land during the wet season. The levels of PAHs obtained were partly attributed to the lack of aryl hydrocarbon hydrogenase (AHH) system in L. littorea. Relative ratios of low molecular weights, LPAHs (<3-ring) compounds to those with high molecular weights, HPAHs (>4-rings) suggested a petroleum related origin for the PAHs detected in the organism. The PAH and bioaccumulation factor (BAF) are significantly correlated (P<0.05, r= 0.908). The levels of PAHs in the tissues were relatively low compared to world-wide locations reported to be chronically contaminated by oil.Keywords: Oil spill, hydrocarbons, gas chromatography; mass spectrometry; periwinkle. Deniz Salyangozu Littorina littorea'da Hidrokarbonun Varlığı ve Dinamikleri ÖzetSucul ortamda meydana gelen küçük kazaların kümülatif etkileri, suda yaşayan canlıların doğal yaşantısında önemli sonuçlara yol açabilir. Akuatik fauna sık sık hidrokarbona maruz kalıp kalmadığıyla ilgili incelenir. Çünkü akuatik faunada hidrokarbonun bulunması direkt olarak içinde yaşayan canlılara ve dolaylı olarak da insanlara tehdit teşkil eder. Nijerya'nın Ondo Eyaletindeki petrol kirliliği bilinen alanlarda ve özenle seçilen iki kıyısal bölgede deniz salyangozu Littorina littorea'nın dokusunda hidrokarbonun içerik ve uzamsal dağılımı özellikle de polisiklik aromatik hidrokarbonların (PAHs) varlığı, alev iyonlaştırıcı detektörlü ve kütle spektrometreli gaz kromotografisi (GC/FID/MS) ile araştırılmıştır. Kirliliğin sürekliliğini ve mekansal boyutunu hem de yan etkilerini değerlendirmek için doku örneklemesi ve analizler yapılmıştır. Bir çoğunun biyodönüşüm ürünleri olduğu düşünülen kompleks seriler halinde bileşikler elde edilmiştir. PAHs dağılımı: sırasıyla kuru ve yaş sezonda ölçülemez (nd) -56,23 µg/g kuru ağırlık (dw) ve nd -79,43 µg/g dw'dir.
