| description | The Mar Menor coastal lagoon is one of the largest of the Mediterranean Sea. Ancient mining activities in the mountains near its southern basin have resulted in metal contamination in the sediment. The metal bioavailability of these sediments was determined through laboratory toxicity bioassays using three Mediterranean sea urchin species and two amphipod species, and by means of field bioaccumulation measurements involving the seagrass Cymodocea nodosa. The effect of sediment metal contamination on benthic communities was assessed through benthic infaunal analyses, applying classical descriptive parameters and multivariate techniques. The sediments affected by the mining activities presented high levels of toxicity and metals were also accumulated in the seagrass tissues, pointing to metal bioavailability. Although the classical benthic indices were not clear indicators of disturbance, the multivariate techniques applied provided more consistent conclusions.
El Mar Menor es una de las mayores lagunas costeras en el Mediterráneo. Actividades mineras desarrolladas históricamente en las montañas situadas en su orilla sur han causado la contaminación por metales de sus sedimentos. La biodisponibilidad de los metales en estos sedimentos fue determinada por medio de bioensayos de toxicidad, empleando tres especies de erizos marinos y dos especies de anfípodos, y por medio de medidas de bioacumulación en la fanerógama marina Cymodocea nodosa. El efecto de la contaminación de los sedimentos por metales en las comunidades bentónicas fue valorado a través de análisis de la infauna bentónica, aplicando parámetros descriptivos clásicos y técnicas multivariantes. Los sedimentos afectados por las actividades mineras presentaron altos niveles de toxicidad y estos metales fueron incluso acumulados en los tejidos de la fanerógama marina, indicando la biodisponibilidad de los mismos. Aunque los índices bentónicos clásicos no resultaron ser claros indicadores de la perturbación, las técnicas multivariantes aplicadas ofrecieron conclusiones más consistentes. |
