Interlaboratory assessment of marine bioassays to evaluate the environmental quality of coastal sediments in Spain. III. Bioassay using embryos of the sea urchin Paracentrotus lividus

 The present paper reports the results of an interlaboratory variability study of a bioassay using larval stages of the marine sea urchin Paracentrotus lividus. This exercise was developed in two different phases and included four laboratories, each of which determined the toxicity of six s...

El presente trabajo resume los resultados del ejercicio realizado para estudiar la variabilidad interlaboratorio del ensayo con estadios larvarios del erizo de mar Paracentrotus lividus. Este ejercicio, que se desarrolló en dos fases distintas, incluyó cuatro laboratorios cada uno de los cuales estudió la toxicidad de las seis muestras de sedimento distribuidas. Las muestras, provenientes de distintos puertos de la costa española, se caracterizaron mediante la exposición de embriones del erizo de mar Paracentrotus lividus durante 48 h a los lixiviados de los sedimentos. La Fase I se utilizó para rediseñar las condiciones del ensayo y evitar posibles factores de confusión al interpretar los resultados. Los resultados de la Fase II fueron más homogéneos al clasificar las muestras según la toxicidad registrada, a pesar de la variabilidad en los protocolos de obtención y ensayo de los lixiviados. De acuerdo con estos resultados, el ensayo es adecuado para la caracterización de este tipo de muestras con una variabilidad interlaboratorio similar a la encontrada para otros bioensayos en estudios interlaboratorio previos. 2006-05-24 2021-06-03T03:55:09Z 2021-06-03T03:55:09Z 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/1040 10.7773/cm.v32i12.1040 https://hdl.handle.net/20.500.12930/7392 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1040/937 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 1B (2006); 139-147 Ciencias Marinas; Vol. 32 Núm. 1B (2006); 139-147 2395-9053 0185-3880
