“…Several techniques are used to identify NPs (<100 nm) in volcanic ash and evaluate their toxic effect. Ermolin et al [ 4 ], studying different Kamchatka volcanoes, describe a separation process of NPs using coiled-tube field-flow fractionation (CTFFF) performed by a rotation column, carrier fluid (generally Milli-Q water), and UV detector for system control. A complete scheme and basic principle of the planetary motion system can be found in Ermolin et al [ 11 ] and Faucher et al [ 12 ].…”

“…The physicochemical speciation and elemental concentration of NPs are analyzed using inductively coupled plasma (ICP)-AES (atomic emission spectroscopy) [ 11 ] and ICP-MS (mass spectrometry) [ 12 ]. Recently, an analytical technique used to analyze the concentration of metalloids in selected volcanic ash NPs has been single-particle (SP) ICP-MS, which can detect a single particle with a low detection limit [ 4 ]. The volcanic ash from Nevado del Ruiz (Colombia) was also studied using field-emission (FE) SEM and high-resolution transmission electron microscopy (HR-TEM) [ 23 ].…”

“…The size and shape of ash particles are of critical importance in health. In the published literature [ 4 , 11 , 21 , 22 , 23 ], various authors have reported the transport, speciation, elemental composition, mineralogy, and pulmonary bioaccessibility of airborne volcanic ash. In particular, fractions smaller than 2 μm are associated with chronic diseases such as silicosis and pneumoconiosis [ 24 ].…”

The inhalation of natural nanoparticles (NPs) emitted from volcanic activity may be a risk to human health. However, the literature rarely reports the fate and response of NPs once in contact with lung fluids. In this work, we studied the particle size distribution of ashfall from Popocatépetl volcano, Mexico. The collected ashes (n = 5) were analyzed with scanning electron microscopy (SEM) to obtain the elemental composition and morphology, and to determine the size of the ash particles using ParticleMetric software (PMS). The PMS reported most of the ash to have submicrometric size (<1 μm) and an average equivalent circle of 2.72 μm. Moreover, to our knowledge, this study investigated for the first time the behavior of ash NPs at different times (0 to 24 h) while in contact with in vitro lung fluid, Gamble Solution (GS) and Artificial Lysosomal Fluid (ALF) using dynamic light scattering (DLS). We found a large variability in the hydrodynamic diameter, with values less than 1 nm and greater than 5 μm. Furthermore, aggregation and disaggregation processes were recognized in GS and ALF, respectively. The results of this study increase the knowledge of the interaction between NPs and lung fluids, particularly within the alveolar macrophage region.

“…It has also been suggested that volcanic plumes may provide a medium to rapidly oxidize entrained atmospheric GEM within minutes (von Glasow, 2010) which would lead to PBM as the dominant Hg species within the nearer distances considered for this study. Alternatively, the more distal samples from both Mount Spurr and Redoubt Volcano contain higher proportions of fine ash material than proximal samples (McGimsey et al, 2001;Wallace et al, 2013), providing a correspondingly higher surface area for adsorption reactions to take place (Ermolin et al, 2018;Ermolin et al, 2021) which would favor higher bulk-sample concentrations of PBM. Despite these pathways potentially favoring a decrease or increase of PBM with distance, respectively, neither process appears to be discernible within the variability of our samples.…”

Ash is a potential sink of volcanically sourced atmospheric mercury (Hg), and the concentration of particle-bound Hg may provide constraints on Hg emissions during eruptions. We analyze Hg concentrations in 227 bulk ash samples from the Mount Spurr (1992), Redoubt Volcano (2009), and Augustine Volcano (2006) volcanic eruptions to investigate large-scale spatial, temporal, and volcanic-source trends. We find no significant difference in Hg concentrations in bulk ash by distance or discrete eruptive events at each volcano, suggesting that in-plume reactions converting gaseous Hg0 to adsorbed Hg2+ are happening on shorter timescales than considered in this study (minutes) and any additional in-plume controls are not discernable within intra-volcanic sample variability. However, we do find a significant difference in Hg concentration of ash among volcanic sources, which indicates that volcanoes may emit comparatively high or low quantities of Hg. We combine our Hg findings with total mass estimates of ashfall deposits to calculate minimum, first-order Hg emissions of 8.23 t Hg for Mount Spurr (1992), 1.25 t Hg for Redoubt Volcano (2009), and 0.16 t Hg for Augustine Volcano (2006). In particular, we find that Mount Spurr is a high Hg emitting volcano, and that its 1992 particulate Hg emissions likely contributed substantially to the global eruptive volcanic Hg budget for that year. Based on our findings, previous approaches that use long-term Hg/SO2 mass ratios to estimate eruptive total Hg under-account for Hg emitted in explosive events, and global volcanogenic Total Hg estimates need revisiting.
