History of heavy metals contamination in lacustrine sediments of Admiralty bay, King George Island, Antarctic Peninsula

A temporal reconstruction of heavy metals contamination in Admiralty bay, King George Island, was conduced through the analyses of sediment profiles. Ages of the layers were determinated using super(210)Pb geochronology. Attempts had been made to examine the history of occupation and exploration of Admiralty bay based on the concentrations of the heavy metals present in the bay. Elements such as Cr, Cu and Ni, associated with paints and petroleum showed an increase in the sediment profiles of the points 1 and 5 that are in the vicinity of the focus areas. The above region has a history of fishing exploration which is nearby this research station.
