- Are coastal resources of NW Portugal fingerprinting hydrocarbons released from the Prestige accident? Cristina Micaelo Ana Maria Ferreira Carlos Vale Ciencias de la Tierra fishes mussels Prestige Portugal hydrocarbons Seventy-one samples of mussels, sardine, hake, blue whiting and pouting from the NW Portuguese coast, collected between18 November 2002 and 6 January 2003, were analyzed for total hydrocarbons, individual n-alkanes and major isoprenoids,pristane and phytane. Hydrocarbons (expressed on chrysene equivalents) registered in whole soft tissues of mussels were below0.5 µg g1, with a few exceptions (maximum 1.6 µg g1). Relatively low levels and sporadic enhanced values were also found infish fillet samples. In spite of this, analyses of individual n-alkanes and major isoprenoids showed that 1061% of the samples(according to the species) exhibited these compounds in the proportions of the Prestige fuel signature. Similar diagnostic ratios inbiological samples and Prestige fuel and n-alkane composition corroborate the fingerprint hypothesis in coastal resources fromNW Portugal. 2003 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48029111 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1 Vol.29
