Interlaboratory assessment of marine bioassays to evaluate the environmental quality of coastal sediments in Spain. V. Whole sediment toxicity test using juveniles of the bivalve Ruditapes philippinarum

Several species of bivalves and procedures have been used to characterize sediment toxicity. Here we report the results of an interlaboratory exercise that included three different laboratories to evaluate the use of the bioassay using the commercial clam Ruditapes philippinarum. Six different dredg...

Here we report the results of an interlaboratory exercise that included three different laboratories to evaluate the use of the bioassay using the commercial clam Ruditapes philippinarum. Six different dredged sediments were studied using two different endpoints: lethality after two different exposure periods (7 and 14 days) and burrowing activity after 48 h of exposure. The lethal endpoint was only sensitive to characterize samples with high metallic concentration and following the 14-day exposure period. The burrowing activity showed very variable results that evidence the unsuitability of this endpoint for dredged material characterization. According to these results, a new design is recommended for the test using juvenile bivalves if it is to be used to characterize sediment samples on a regulatory context especially if sediments are not affected by metallic contamination. Este estudio resume los resultados del ejercicio interlaboratorio realizado en tres laboratorios para evaluar el uso del ensayo con la almeja comercial de Manila Ruditapes philippinarum. Seis muestras de sedimentos dragados se estudiaron mediante dos medidas finales distintas: mortalidad tras dos periodos de exposición distintos (7 y 14 días) y la medida subletal que estudia el porcentaje de organismos enterrados tras 48 h desde el inicio de la exposición. La medida de la letalidad fue sólo sensible tras el periodo más largo de exposición y la contaminación metálica más elevada. La actividad de enterramiento mostró resultados muy variables y altamente dependientes del operador responsable. De acuerdo con estos resultados se recomienda la revisión del protocolo para mejorar su uso en la gestión de dragados portuarios especialmente si se trata de zonas no afectadas por contaminación metálica. 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/1030 10.7773/cm.v32i12.1030 https://hdl.handle.net/20.500.12930/7388 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1030/933 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 1B (2006); 159-166 Ciencias Marinas; Vol. 32 Núm. 1B (2006); 159-166 2395-9053 0185-3880
