12c – Speciation and isotope analysis of metal ions in aerosols related to their source and chemical processes
Description
Speciation and isotopic analyses of metal ions in different types of aerosols have been carried out to understand their sources and chemical processes during long-range transport and after deposition. For example, Fe isotopes in aerosols transported to the HNLC region in the ocean have been measured to know their sources and the speciation of Fe is important to discuss its fractional solubility in seawater, both of which are important to understand the supply of soluble Fe to the ocean as a nutrient for phytoplankton. Similarly, speciation and isotopic analysis are important for Zn, Cu, Ni, and any other metal ions in aerosols, which are important from a number of perspectives. We encourage the submission of all geochemical and environmental studies that analyze either speciation or isotope ratios or both for metal ions in aerosols to extract all information in aerosols from all sources such as anthropogenic sources and natural sources emitted from arid areas and volcanoes. Analyses of aerosols in the past to understand the atmospheric environment in the Anthropocene are also included in this session. All studies on advanced analytical techniques for speciation and isotopic analysis of aerosols and laboratory studies simulating any processes such as combustion aerosol formation and dissolution in water are also welcome.
