“…Likewise, amphipod survival (e.g., Hyalella azteca, Eohaustorius esturius) has been often used to evaluate sediment toxicity in recent years (Ingersoll et al, , 1996Kemble et al, 1994Kemble et al, , 1998Kemble et al, , 1999Bhattacharyya et al, 2003;Blaise et al, 2004). In comparison to other biotests, such as echinoid fertilization, microinvertebrate embryo-larval toxicity, and induction of mixed function oxygenase, the Microtox 1 SPT and amphipod tests appeared among the most sensitive assays for evaluating toxicity of sediments and interstitial waters during oil spill impact assessment (Lee et al, 2003a).…”

ABSTRACT:The potential ecological impacts of anaerobic degradation of vegetable oil on freshwater sediments were investigated. Sediment toxicity was evaluated using two regulatory biotests: the Microtox 1 Solid Phase Test and an amphipod (Hyalella azteca) bioassay. The results of the Microtox test showed that the toxicity of the vegetable-oil-contaminated sediments (about 17-33 g oil/kg dry sediments) increased after 2 weeks incubation and then decreased to near background levels after incubation for 8 weeks under anaerobic conditions. The amphipod toxicity bioassay showed that the toxicity of fresh contaminated sediments decreased over time and returned to background levels within 8 weeks. These results suggest that the impact of vegetable oils on organisms within sediments may be limited. To account for the significance of environmental conditions, additional studies over a wide range of incubation conditions (e.g., temperature, nutrient concentration) and other test organisms at various trophic levels are recommended for both acute and chronic toxicity assessment. #

“…However, it may be suggested that the enzymes that catalyze the utilization of naphthalene in the concerned organisms, especially in the contaminated soils, are especially sensitive to high concentrations of nickel, in addition to other possible components of contaminated oil. Such components include other heavy metals like cadmium, vanadium [22], hydrocarbon fractions [23], and their degradation products [24]. Furthermore, since the isolated aliphatic and aromatic hydrocarbonsdegrading bacteria were generally similar (data not shown), it can be deduced that the sensitivity of naphthalene degradation to added nickel was not genusspecific but most probably pathway-specific.…”

Assessment of nickel contents in soil samples in Kuwait indicated only a minor difference in concentration in hydrocarbon-contaminated (86 mg kg(-1) soil) and non-contaminated soils (84 mg kg(-1) soil). The potential inhibitory effects of nickel on the number of hydrocarbon degraders, and hydrocarbon utilization were investigated over a wide range of nickel concentrations to span concentrations observed in the soil. Nickel addition, as nickel sulphate, to soil samples reduced the number of hydrocarbon degraders in all samples by a wide range (15-96%) depending on concentration and the hydrocarbon substrate utilized. Similarly, the metabolic activities were affected as observed in mineralization (3-60%) of soils amended with various concentrations of nickel. The inhibitive effects of nickel on hexadecane and crude oil utilization were minimal but were significantly higher with naphthalene (P < 0.05) in both hydrocarbon-contaminated and non-contaminated soils. Polarographic determination of hydrocarbons induced oxygen uptake rate demonstrated the tendency of nickel to significantly inhibit (P < 0.05) the oxidation of polyaromatic hydrocarbons compared to aliphatic hydrocarbons.

“…As part of the long-term monitoring of the spilled Arrow oil, samples have been collected 22, 23-30, and 35 years post-spill (Lee et al 2003, Owens et al 2008a, Wang et al 1994. Substantial biodegradation has depleted most resolved components, such as n-alkanes and polycyclic aromatic hydrocarbons (PAHs), particularly within the near-surface deposits.…”

“…The earlier studies of oil residues from the Arrow (Lee et al 2003, Owens et al 2008a, Owens et al 2008b, Vandermeulen & Singh 1994, Wang et al 1994) investigated only components detectable by gas chromatography (GC). In addition to these GC-detected targets, there exist many oxygenated intermediates, which are produced through the biodegradation and (or) photo-oxidation of oil.…”

Purpose This study aimed to investigate the occurrence, fate, and behaviour of oil components 46 years post-spill by analysing polar naphthenic acid fraction components (NAFCs). Methods Oil residues and sediment samples were collected from the shoreline of Chedabucto Bay, Nova Scotia, Canada, at sites affected by the 1970 Arrow oil spill, in June 2016. Sediments were extracted with Soxhlet extraction; NAFCs were separated through a silica gel column firstly, then analysed by high-performance liquid chromatography–high-resolution mass spectrometry (HPLC-HRMS). Results and discussion In all samples, the most abundant NAFC species were those having only oxygen as the heteroatom (Oo species, o indicating the number of oxygen atoms, from 1 to 8) and a high degree of saturation. O2 species accounted for 50–70% of all Oo species. NAFCs with sulphur heteroatoms were the second abundant species, then by those containing both nitrogen and oxygen heteroatoms. NAFCs in most Arrow oil residues had higher levels of oxygen species, especially for heavier molecular weight congeners, than the oil remaining stored in the sunken tanker. Environmental sediment samples, collected from near a marina away from the spill site, mainly contained a biological contribution with obviously recent petroleum oil input, whereas all Arrow oil residues were composed mainly of NAFCs that are characteristic of petroleum, and varied abundance between sites. Conclusions Characteristics of NAFCs from different sources varied from each other. Site-specific environmental conditions played a major role in controlling the fate and behaviour of oil components, including NAFCs.
