    Method development for trace-level analyses of phosphite in chloride-rich matrices. Dataset includes linearity data from the ion chromatograph (IC) in stand-alone mode and coupled to the inductively-coupled plasma mass spectrometer (ICP-MS), with and without removing chloride from the solution, as well as nuclear magnetic resonance (NMR) data for phosphorus species. The results demonstrate successful removal of the chloride matrix for analyses of phosphite in solutions at sub-ppb concentrations. Additional details about the methodology are published in Baidya, A.S. and Stüeken, E.E., 2024, Rapid Communications in Mass Spectrometry, 38(1), p.e9665.

    The dataset has been published open-access in Ilyinskaya et al. (2017), Earth and Planetary Science Letters, 472, 309-322 https://doi.org/10.1016/j.epsl.2017.05.025 This study quantifies the air quality impact of Holuhraun eruption 2014-2015 on populated areas in Iceland. Specifically we trace the evolution of the plume chemistry from the eruption site to 2 key areas of population: Reykjahlid, which is the nearest municipality to Holuhraun at 100 km distance, and Reykjavik capital area, which hosts ~60% of Iceland's population, 250 km distance. This dataset is the full chemical analysis of filter pack samples of volcanic gas and aerosol, including trace species (e.g. heavy metals).
