Interlaboratory assessment of marine bioassays to evaluate the environmental quality of coastal sediments in Spain. I. Exercise description and sediment quality
description  The results of an interlaboratory assessment made to evaluate the use of different bioassays for sediment quality characterization for a regulatory purpose are presented. The objective of the study was to determine the main differences among sediment bioassays conducted at different laboratories and to evaluate how this can influence dredged material management. The exercise consisted of two parts. During Phase I, six dredged sediment samples from different Spanish ports (Barcelona, Bilbao, Cádiz, Cartagena and Huelva) were distributed to different laboratories where they were applied a screening test for initial toxicity evaluation, a test for elutriates and two solid-phase bioassays. In Phase II, six new sediment samples (from the ports of Algeciras, Bilbao, Cádiz and Huelva) were tested to re-evaluate some bioassays for which different interfering factors were identified during the first phase. The chemical characterization results for Phase I showed high concentrations of some compounds in all the samples except one, which could be considered uncontaminated, while those for Phase II showed high concentrations in most sediments of some metallic compounds, mainly Cu, Hg and As, and to a lesser extent Cd, and of the total polychlorinated biphenyl congeners analyzed. According to Spanish guidelines for dredged material management, only one of the six samples assessed in each phase of the exercise would be suitable for open water disposal.

El presente trabajo resume la organización del ejercicio interlaboratorio para distintos ensayos de toxicidad realizados sobre sedimentos de puertos españoles así como los resultados de la caracterización fisicoquímica de las muestras utilizadas. El ejercicio, que incluyó cuatro bioensayos (un ensayo comercial para la evaluación inicial de la toxicidad de los sedimentos, un ensayo para evaluar la toxicidad de los lixiviados y dos ensayos sobre la fase sólida) se desarrolló en dos fases. En la Fase I se distribuyeron a cada uno de los distintos laboratorios participantes seis muestras de sedimentos dragados en diferentes puertos alrededor de la costa española (Barcelona, Bilbao, Cádiz, Cartagena y Huelva) cuya toxicidad fue evaluada mediantelos ensayos seleccionados. La Fase II, que incluyó seis nuevas muestras de sedimento (provenientes de los puertos de Algeciras, Bilbao, Cádiz y Huelva), incluyó sólo dos ensayos para los que se habían identificado distintos factores de confusión durante la primera fase del ejercicio. Los resultados de la caracterización química de las muestras arrojaron, en la mayoría de los sedimentos, altas concentraciones de determinados elementos metálicos, principalmente Cu, Hg y en menor medida As y Cd, y de los compuestos bifenilos policlorados medidos. De acuerdo con las concentraciones encontradas y las guías de calidad de sedimentos usadas en España para la gestión de dragados portuarios, cinco de las seis muestras de sedimentos que se usaron en cada fase del ejercicio se considerarían materiales con concentraciones altas de contaminantes y, por ende, su vertido al mar no sería permitido. 2006-05-24 2021-06-03T03:55:08Z 2021-06-03T03:55:08Z 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/1032 10.7773/cm.v32i12.1032 https://hdl.handle.net/20.500.12930/7390 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1032/935 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 1B (2006); 121-128 Ciencias Marinas; Vol. 32 Núm. 1B (2006); 121-128 2395-9053 0185-3880
