“…After the accident involving the tanker Prestige in November 2002, that washed up the coastline of Galicia (NW Spain), numerous studies were carried out to determine the accumulation and distribution of polycyclic aromatic hydrocarbons (PAHs) in water, sediments and biota (Carro et al 2006;Franco et al 2006;González et al 2006;Viñas et al 2009) as well as along the north-west Portuguese coast (Ferreira et al 2003). In most of these studies mussels were used as bioindicators both to determine the change over time and distribution of accumulated hydrocarbon levels (Nieto et al 2006;Soriano et al 2006) and to study their biological effects Marigómez et al 2006;.…”

The aim of this study was to assess environmental quality at some of the sites most severely affected by the Prestige oil spill off 2 years after the spillage (April and November 2004). For this purpose analyses of polycyclic aromatic hydrocarbons (PAH) and several biochemical (antioxidant enzymes catalase, glutathione reductase, glutathione peroxidase, superoxide dismutase and DT-diaphorase and lipid peroxidation) and physiological [scope for growth (SFG)] biomarkers were determined on wild mussel populations (Mytilus galloprovincialis) collected at four points along the Costa da Morte and compared with those of a reference site not affected by the oil spill. Results showed that PAH contents had markedly decreased 17 months after the accident, although they were higher in April than in November, when they showed values similar to background levels reported for this area. Nevertheless, the predominance of chrysene on PAH profiles, similarly to findings obtained immediately after the spill, indicated the Prestige as their main source. In spite of the low PAH levels recorded, antioxidant activity levels (explained through the integrated antioxidant response-IAR) were higher in the Costa da Morte than at the reference site either in April and November. In April IAR seems to be related to PAH levels found 3 months after the accident (February 2003), suggesting the persistence in the environment of oxidative stress-producing components from the spill. However, evidence of oxidative stress was not reflected at physiological level by scope for growth, with only very slight differences being observed between values from the reference site and those from Costa da Morte sites. In conclusion, although 2 years after the spill PAHs bioaccumulated by mussels from the Costa da Morte had decreased to background levels, biochemical parameters showed signals of oxidative stress in mussels from this area. However, SFG reflected a good health status for the mussel populations studied and did not reveal evidence of physiological disturbance either 17 or 24 months after the Prestige spill.

“…2b), the dominant n-alkanes found in sediments ranged from C 24 to C 29 , and no clear odd to even predominance was seen. The predominance of odd n-alkanes suggests the presence of both phytoplankton (high levels of lower odd carbon number) and terrestrial plant (high levels of higher odd carbon number) hydrocarbons, indicating a strong biogenic input (Carro et al 2006). The freezing river in icebound season may reduce the hydrocarbon input from terrestrial plant and biogenic activities.…”

This paper presents the spatial and temporal characteristics of petroleum hydrocarbons (PH) in surficial sediments from the Songhuajiang River using the method of petroleum chemical fingerprinting. Twenty-four surface sediment samples were collected at 17 sites along the river from upstream to downstream in flood season (August 2005) and icebound season (December 2005) and were analyzed for PH including n-alkanes (C(16)-C(33)), isoprenoid alkanes (pristane and phytane), and unresolved complex mixture (UCM). The concentration of PH varied from 22.64 to 91.45 μg g( -1) dry sediment. n-alkanes with a carbon number from 16 to 33 were detected in all samples, and the UCM was the dominant composition for PH. The variability of the PH concentration was mostly influenced by external conditions, such as seasonal change and industrial area position, as well as internal sediment physicochemical properties, such as organic carbon and grain size. The concentration of hydrocarbons is higher in flood season than in icebound season and is higher upstream than downstream. The diagnostic ratios of specific hydrocarbons showed that the PH pollution comes from a combination of biogenic and petrogenic sources, and petrogenic input is dominant in icebound season relative to flood season. It also indicates that there is a clear terrigenous input of n-alkanes in flood season. Principal components analysis was used to study the composition and characteristics of PH in Songhuajiang River sediments and to assess the spatial and temporal distribution of their natural and anthropogenic sources.
