- Assessment of sediment metal contamination in the Mar Menor coastal lagoon (SE Spain): Metal distribution, toxicity, bioaccumulation and benthic community structure Lázaro Marín-Guirao Arnaldo Marín Rubén Vita Augusto Cesar Ciencias de la Tierra metals toxicity seagrass amphipods sea urchins The Mar Menor coastal lagoon is one of the largest of the Mediterranean Sea. Ancient mining activities in the mountains nearits southern basin have resulted in metal contamination in the sediment. The metal bioavailability of these sediments wasdetermined through laboratory toxicity bioassays using three Mediterranean sea urchin species and two amphipod species, and bymeans of field bioaccumulation measurements involving the seagrass Cymodocea nodosa. The effect of sediment metalcontamination on benthic communities was assessed through benthic infaunal analyses, applying classical descriptive parametersand multivariate techniques. The sediments affected by the mining activities presented high levels of toxicity and metals werealso accumulated in the seagrass tissues, pointing to metal bioavailability. Although the classical benthic indices were not clearindicators of disturbance, the multivariate techniques applied provided more consistent conclusions. 2005 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48031209 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.2 Vol.31
