  1. 1. If Trees Could Talk - Dendrochemistry, a Promising Method for Understanding Pollution History

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jonatan Uusitalo; [2023-08-17]
    Nyckelord :;

    Sammanfattning : Heavy metal pollution presents a significant environmental challenge in the Anthropocene era, and understanding pollution history is crucial to address historical pollution and implementing effective mitigation measures. This study stands among a few comprehensive dendrochemical investigations that utilized an extensive dataset and energy dispersive X-ray fluorescence (EDXRF) technique to reconstruct the contamination history of As, Cd, Cu, Ni, Pb, and Zn, with a focus on Cu.
