Analysis of zinc speciation and stable isotope ratio of past aerosols in SE-Dome II ice core, Greenland.

Abstract

The chemical properties of aerosols reflect changes in anthropogenic activities and natural environments, with past aerosols preserved in ice cores. In this study, we aimed to elucidate the relationship between modern anthropogenic activities and aerosol chemical properties by examining zinc speciation and stable isotope ratios in past aerosols from the SE-Dome II ice core, which provides a high-resolution record from 1800. In terms of Zn speciation, we identified Zn sulfate and other species that have reacted with anthropogenic gases. Additionally, we will present the progress of our zinc isotope measurement.
