Stream bottom sediments as a mean to assess metal contamination in the historic mining district of Almadén (Spain).

Located in the southern half of Spain, Almadén is the world?s largest Hg district and mercury has been mined there for over 2000 years. Its slag heaps and old metallurgy plants represent a risk to watercourses that flow through the district and receive the run-off from the mines. This study collecte...
