Monitoring biomarkers in fish (Lepidorhombus boscii and Callionymus lyra) from the northern Iberian shelf after the Prestige oil spill

Stress Biomarkers in Juvenile Senegal Sole, Solea senegalensis, Exposed to the Water-Accommodated Fraction of the “Prestige” Fuel Oil

“…Nevertheless, we can not exclude the possibility that long-term chronic exposures to low levels of the crude oil can induce toxicity and compromise sole reproductive status as has been pointed out in other benthic fish species (Monteiro et al 2000;Martin-Skilton et al 2006;Sturve et al 2006;Martínez-Gómez et al 2006).…”

“…Nevertheless, in a field study with two species of flatfish, taken from the polluted site, effects on antioxidant defences and xenobiotic metabolising enzymes were observed, partially related to tar aggregate concentrations. However, a cause-effect relationship due solely to the ''Prestige'' oil spill could not be established because of the existence of chronic pollutants from local industries already present in some of the sampled areas (Martínez-Gómez et al 2006). Other factors to consider are the route and time of exposure.…”

Cryopreservation and storage of mussel (Mytilus spp.) haemocytes for latent analysis by the Comet assay

“…For example, field surveys have shown that industrialised estuaries are impacted with a range of contaminants, some of which are known to display genotoxic activity [5,6]. Accidental discharges also contribute to the contamination of the marine environment as exemplified by the Deepwater Horizon accident resulting in the release of 600,000 tonnes of crude oil into the Gulf of Mexico [7] and the sinking of the tanker 'Prestige' in November 2002, which led to 60,000 tonnes of fuel oil polluting the coastline of Galicia with polycyclic aromatic hydrocarbons (PAHs) and heavy metals such as nickel [8].…”

Impact Assessment of Diesel Oil on the Zhe Oyster (Crassostrea plicatula) Using RAPD Analysis

“…Marine pollution due to oil and oil exploration pollution in ocean environments is an especially critical environmental concern [3]. Most previous studies have focused on the effects of oils on survival [4][5][6][7][8][9][10][11], morphological parameters [9,11,12], hematological physiological parameters [9,12,13], biochemical parameters [14][15][16][17][18][19][20][21] and histological parameters [13,18,19]. In addition, the molecular level changes of oil on aquatic organisms, such as micronucleus frequency, DNA repair, cytochrome P4501A, DNA adducts, DNA single strand breaks, microsatellite and AFLP loci were also studied [22][23][24][25][26][27].…”
