Seagrass soil archives reveal centennial-scale metal smelter contamination while acting as natural filters
Unidad de excelencia María de Maeztu MdM-2015-0552 The upper Spencer Gulf in South Australia hosts the world's largest single stream Pb-Zn smelter, which has caused environmental and health issues related to elevated metal concentrations in the surrounding environment. The area also has extensi...
