Characterization of hydrocarbons in sediments from Laxe Ria and their relationship with the Prestige oil spill (NW Iberian Peninsula)

Surface sediment samples were collected from Laxe Ria (NW Spain) in September 2003 in order to characterize the extractable organic matter and compare it with the fuel oil spilled by the Prestige tanker. The valoration of polycyclic aromatic hydrocarbons by gas chromatography and gas chromatography-...

The valoration of polycyclic aromatic hydrocarbons by gas chromatography and gas chromatography-mass spectroscopy indicated an organic similarity in the middle part of the ria of pyrolytic origin. On the other hand, the comparison of different fragmentograms of characteristic ions (m/z 85 [n-alkanes], m/z 128 [naphthalene], m/z 142 [alkylnaphthalenes], m/z 156 [dialkylnaphthalenes], m/z 178 [phenanthrene or anthracene], m/z 202 [fluoranthene or pyrene], m/z 228 [benzo(a)anthracene or chrysene], and m/z 252 [benzofluoranthenes, benzopyrenes and perylene]) revealed that the organic matter extracted from the sediments did not correspond to the Prestige oil spill. En septiembre de 2003 se recogieron muestras de sedimento superficial en la Ría de Laxe (NW de la Península Ibérica) con el fin de caracterizar lamateria orgánica extraíble y compararla, además, con el fuel oil procedente del vertido del petrolero Prestige recogido en la Costa de la Muerte. La valoración de determinados hidrocarburos aromáticos policíclicos mediante cromatografía de gases y cromatografía de gases-espectrometría de masas denota una similitud orgánica en la parte media de la ría y establece para ellos un origen pirolítico. Por otra parte, tras la comparación de distintos fragmentogramas de iones característicos: m/z 85 (n-alcanos), m/z 128 (naftaleno), m/z 142 (alquilnaftalenos), m/z 156 (dialquilnaftalenos), m/z 178 (fenantreno o antraceno), m/z 202 (fluoranteno o pireno), m/z 228 (benzo(a)antraceno o criseno) y m/z 252 (benzofluorantenos, benzopirenos y perileno), no se observa que la materia orgánica extraída de los sedimentos corresponda al vertido del Prestige. 2006-08-21 2021-06-03T03:55:14Z 2021-06-03T03:55:14Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1084 10.7773/cm.v32i22.1084 https://hdl.handle.net/20.500.12930/7411 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1084/1923 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 2B (2006); 429-437 Ciencias Marinas; Vol. 32 Núm. 2B (2006); 429-437 2395-9053 0185-3880
