Long-range transport of La Soufriere volcanic plume to the western North Pacific: Influence on atmospheric mercury and aerosol properties

Saginela Ravindra Babu et al.

Summary: This study provides the first evidence of enhanced mercury levels up to 18000 km downwind from a volcano source, showcasing the significant impact of volcanic eruptions on long-distance mercury concentrations. The observations of mercury and aerosol transport over Taiwan during the volcanic plume event highlight the atmospheric processes involved in such events.

Earth system modeling of mercury using CESM2-Part 1: Atmospheric model CAM6-Chem/Hg v1.0

Peng Zhang et al.

Summary: In this study, an online model using the atmospheric component of the global climate model CESM2 was developed to simulate the cycling of atmospheric mercury. The model successfully reproduced the spatial distribution of total gaseous mercury and wet deposition fluxes. Factors affecting the seasonal variations of atmospheric mercury were also investigated.

Nanospeciation of metals and metalloids in volcanic ash using single particle inductively coupled plasma mass spectrometry

Mikhail S. Ermolin et al.

Summary: Volcanic activity is a main source of natural nanoparticles, with toxic metals/metalloids in volcanic ash nanoparticles potentially being one or two orders of magnitude higher than in bulk samples. The fate and behavior of these toxic elements depend on their binding type to nanoparticles, indicating a need to distinguish element species adsorbed onto pyroclastic nanoparticles from individual nanophases of metal/metalloid oxides or salts. This study utilizes single particle inductively coupled plasma mass spectrometry to analyze nanoparticles from Kamchatka volcanoes, revealing that the nanospeciation of various elements is dependent on both element type and volcano source.

Fifty years of volcanic mercury emission research: Knowledge gaps and future directions

Brock A. Edwards et al.

Summary: Volcanism is a potentially important natural source of mercury (Hg) to the environment, but its impact on the global Hg cycle is poorly understood, leading to uncertainty in assessing the relative contributions of natural and anthropogenic Hg sources to the global atmosphere. Research shows that arc volcanoes emit 3-fold higher Hg fluxes on average compared to non-arc volcanoes, despite the latter having significantly higher Hg concentrations in their plumes.

Rapid metal pollutant deposition from the volcanic plume of Kilauea, Hawai'i

Evgenia Ilyinskaya et al.

Summary: Through extensive sampling of Kilauea's 2018 eruption plume, it was found that volatile metal pollutants in basaltic volcanic plumes can be deposited up to 100 times faster than refractory species, potentially producing disproportionate impacts at proximal locations. The relationship between volatility and solubility was identified as an important control on the atmospheric behavior of elements, suggesting that assessment of hazards from volcanic emissions should consider heterogeneous plume depletion of metal pollutants.
