Trace metal contents in water and sediments in Samborombón Bay wetland, Argentina
Samborombón Bay is the most extensive myxohaline wetland of Argentina. This Ramsar site is considered a priority area for the conservation of biodiversity in the country. Numerous rivers and channels that drain the Pampean plain, such as the Salado River and the channels Lower Salado, 15, 9, A, 1, a...
