Impacto humano en la ría de Suances (Cantabria): indicadores geoquímicos y microfaunísticos en los sedimentos actuales
Metal and benthic foraminiferal contents from surface sediments of the Suances estuary have been analyzed in order to characterize the geochemical and microfaunal responses to the present environmental conditions in this coastal area. High levels of Zn, Pb, and Cd together with reduced numbers of fo...

| Resumo: | Metal and benthic foraminiferal contents from surface sediments of the Suances estuary have been analyzed in order to characterize the geochemical and microfaunal responses to the present environmental conditions in this coastal area. High levels of Zn, Pb, and Cd together with reduced numbers of foraminifera present in this estuary suggest very negative and persistent environmental conditions through time as a consequence of mining, industrial and urban effluents disposal in this ecosystem during the last 160 years. Multiproxy geological analysis represents a powerful tool for the historical monitoring of both the past and future environmental transformation processes |
