The performance of these techniques was assessed in a validation study and the results were compared with the traditional chemical characterization. This study included two phases and showed promising results in particular for the Microtox® bioassay, the bioassay using crustacean amphipods and the embryo-larval development bioassay using sea urchins.

The results of this analysis showed that the toxic responses were correlated to different contaminants measured in the sediments. Para estudiar si los bioensayos de toxicidad cumplen ciertos criterios a nivel nacional se realizó un ejercicio interlaboratorio diseñado principalmente para estudiar el desarrollo, la optimización y la validación de los métodos disponibles para la evaluación de la toxicidad en material de dragado. Se evaluó la eficiencia y la utilidad de este tipo de técnicas y se compararon los resultados de toxicidad obtenidos con la caracterización química tradicional. Este ejercicio incluyó dos fases y mostró resultados satisfactorios especialmente para el ensayo Microtox®, el ensayo con el desarrollo embrionario del erizo de mar y el ensayo con anfípodos. Estos tres ensayos parecen factibles y ofrecen información útil para la gestión de dragados portuarios. Los resultados del análisis multivariante realizado para unir la toxicidad y la contaminación registrada con los ensayos mostraron que las respuestas tóxicas registradas están correlacionadas en mayor o menor medida con los distintos contaminantes analizados en el sedimento. 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/1029 10.7773/cm.v32i12.1029 https://hdl.handle.net/20.500.12930/7387 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1029/932 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 1B (2006); 167-177 Ciencias Marinas; Vol. 32 Núm. 1B (2006); 167-177 2395-9053 0185-3880 |
