Monitoring photooxidation of the Prestige's oil spill by attenuated total reflectance infrared spectroscopy

Monitoring Polycyclic Aromatic Hydrocarbon Pollution in the Marine Environment after the Prestige Oil Spill by Means of Seabird Blood Analysis

“…Although after the wreck the composition of the Prestige oil was probably altered by weathering (44), naphthalene was also the dominant parent compound found in subsurface waters (45) and intertidal sediments (46) from oiled areas immediately after spill. In contrast, gulls from unoiled colonies showed low naphthalene percentages (6-12%), and profiles were dominated by PAHs with a large number of benzene rings (g4 rings), especially in Pantorgas and Ansarón colonies, indicative of a rather pyrogenic source of contamination.…”

“…The organisms were incubated for 13 days at 20 ± 1 • C in dark/light conditions. Fresh Statfjord crude oil was artificially weathered [29,30] to simulate the loss of the more volatile compounds (42 wt% of the total hydrocarbon content) that would typically occur due evaporation in the first few days of a light and mid-weight oil spill [31]. Briefly, 8 g of weathered crude oil dissolved in 10 ml of dichloromethane were added to a glass beaker and mixed with 40 g quartz sand [32].…”

Comparing the weathering patterns of six oils using 3-way generalized Procrustes rotation and matrix-augmentation principal components

“…The Prestige and IFO fuel oils were heavy residues of refinery distillation processes. Technical details on the spillages can be found elsewhere [19]. In total, 17 aliquots of the oil lumps were taken on time, and they are referred to as 'weathering samples', which is a short for 'samples taken along the weathering process from each spilled oil'.…”
