Metal complexation capacity of Antarctic lacustrine sediments
The purpose of this study is to implement a work that is a part of a project funded by the Italian National Antarctic Research Program (PNRA, Piano Nazionale di Ricerche in Antartide) within the main thematic focus “Chemical Contamination-Global Change”.
