Level of contamination in sediments affected by the Prestige oil spill and impact on the embryo development of the sea urchin

 The level of contamination in sediments from several sites on the coast of Galicia (Spain) diversely affected by the Prestige oil spill was evaluated 18 months after the accident. Data of metal and total hydrocarbon concentrations in sediments were integrated with data on the toxicity of t...

Data of metal and total hydrocarbon concentrations in sediments were integrated with data on the toxicity of these sediments on sea urchin embryos, obtained through bioassays using an aqueous sediment extract (elutriate) containing the soluble phase of fuel.

Transcurridos 18 meses desde el desastre provocado por el accidente del buque petrolero Prestige, se evaluó el estado de polución del sedimento de varios puntos de la costa gallega afectados en diferente grado por el vertido. Para ello se integraron datos de concentración de metales e hidrocarburos totales en sedimento, con datos de toxicidad de dichos sedimentos sobre embriones de erizo de mar, obtenidos mediante bioensayos realizados con un extracto acuoso del sedimento (lixiviado) conteniendo la fase soluble del fuel. Los resultados de los análisis químicos muestran que en algunos puntos se concentran niveles significativamente elevados de hidrocarburos y metales y además en algunos de estos casos pueden pasar a la columna de agua quedando disponibles para los organismos planctónicos, como demuestran los resultados de los bioensayos realizados con las fases larvarias de una especie local de erizo de mar (Paracentrotus lividus). 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/1085 10.7773/cm.v32i22.1085 https://hdl.handle.net/20.500.12930/7412 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1085/1922 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 2B (2006); 421-427 Ciencias Marinas; Vol. 32 Núm. 2B (2006); 421-427 2395-9053 0185-3880
