Resumen
Muchos contaminantes orgánicos e inorgánicos que se originan desde las actividades humanas son depositados y concentrados en los sedimentos acuáticos. El propósito de este trabajo de revisión, es analizar y discutir los objetivos, metodologías y aplicaciones de los bioensayos en sedimentos marinos, y reflexionar sobre la posibilidad de implementar regulaciones en el monitoreo ambiental de estos estudios en nuestro país para mejorar la calidad ambiental y su manejo en zonas costeras. El principal objetivo es exaltar el entendimiento de la apropiada aplicación e interpretación de los bioensayos. Se presenta un resumen de reportes, conocimientos y análisis relacionados con los sedimentos marinos, la determinación de la toxicidad de sedimentos incluyendo, el análisis químico, la determinación directa de cambios ecológicos, los bioensayos de toxicidad y las líneas multiplex de evidencia, los objetivos de la pruebas de toxicidad de sedimentos, las metodologías y consideraciones mas importantes de bioensayos en sedimentos completos. Una de las conclusiones más convincente que se presenta sería evaluar la calidad ambiental no solo evaluando la química del sedimento y la estructura de la comunidad bentónica, sino incorporando las pruebas de toxicidad como una línea de evidencia fundamental en la triada de calidad del sedimento.

Abstract
Toxicity bioassays in marine sediments
Many organic and in organic contaminants originated from human activities are deposited and concentrated in aquatic sediments. The purpose of this review article is to analyze and discuss, the objectives, procedures and applications of bioassays on the triad of marine sediments, aiming at a reflection on the possibility of implementing regulations on the environmental monitoring of these studies in our country, so as to improve the environmental quality and its management on coastal zones. The main objective is to highlight the understanding of the adequate application and interpretation of bioassays. A summary of reports is presented, knowledge and analysis concerning marine sediments including, the chemical analysis, the direct determination of ecological changes, the toxicity bioassays and the lines of multiple evidence, the objectives of the toxicity test on sediments, the most important approaches and considerations of bioassays on whole sediments. One of the most convincing conclusions is the need of evaluating the environmental quality not only testing the chemistry of the chemistry of the sediment and structure of the benthic community, but incorporating the toxicity tests as a line of fundamental evidence on the triad of sediment quality.
Key words: Toxicity, bioassays, marine sediments, triad and environmental quality.
