Unoccupied aircraft systems (UAS) are developing into fundamental tools for tackling the grand challenges in volcanology; here, we review the systems used and their diverse applications. UAS can typically provide image and topographic data at two orders of magnitude better spatial resolution than space-based remote sensing, and close-range observations at temporal resolutions down to those of video frame rates. Responsive deployments facilitate dense time-series measurements, unique opportunities for geophysical surveys, sample collection from hostile environments such as volcanic plumes and crater lakes, and emergency deployment of ground-based sensors (and robots) into hazardous regions. UAS have already been used to support hazard management and decisionmakers during eruptive crises. As technologies advance, increased system capabilities, autonomy, and availabilitysupported by more diverse and lighter-weight sensors-will offer unparalleled potential for hazard monitoring. UAS are expected to provide opportunities for pivotal advances in our understanding of complex physical and chemical volcanic processes. Non-technical SummaryUnoccupied aircraft systems (UAS) are developing into essential tools for understanding and monitoring volcanoes. UAS can typically provide much more detailed imagery and 3-D maps of the Earth's surface, and more frequently, than satellites are able to. They can also make measurements and collect samples for geochemical analysis from hazardous regions such as volcanic plumes and near active vents. Through being quick to deploy, they offer key advantages during initial stages of volcano unrest as well as throughout eruptions. Data from UAS have already been used to support hazard management and decision-makers during crises. In the future, UAS will become increasingly capable of flying longer and more complex missions, more autonomously and with more sophisticated sensors, and are likely to become key components of broader sensor networks for monitoring and research.

“…The speciation of volatile trace elements as they are emitted at the lava-air interface provides key initial conditions for the subsequent atmospheric transport, solubility, deposition and resulting hazard from these elements (Ilyinskaya et The speciation of volatile trace elements at thermodynamic equilibrium during volcanic degassing has been modelled at several arc volcanoes (e.g. 13,43 ) however models of trace element speciation at intraplate volcanoes are rarer. Factors that control the speciation of elements in volcanic gas emissions include the temperature at the point of degassing, the composition of the parent magma, the amount of atmospheric mixing before 'quenching' (i.e.…”

“…Volcanogenic metal emissions have been sampled and studied at many volcanoes worldwide (e.g. [6][7][8][9][10][11][12][13] ), and early studies date back to the 1960s and 70s (e.g. 14,15 ).…”

“…Here, we use emanation coefficients to quantify element volatility in the magmatic plume, and X/SO2 ratios to demonstrate the consistency of Kīlauea's volatile metal fingerprint across different eruptive periods (Table S11). We also use a Gibbs Energy Minimisation algorithm to model speciation during the oxidation and cooling of Kīlauea's magmatic plume close to the lava-air interface, and we add to existing direct observations, experimental and modelling evidence (e.g 11,13,[42][43][44] ) of the importance of chloride as a control on trace metal degassing (Tables S20-S27). Our study of the laze plume reveals that late-stage degassing of distal lava flows at the ocean entry contains volatile metals that complex with chloride (e.g.…”

Volcanoes represent one of the largest natural sources of metals to Earth’s surface. Emissions of these pollutants and/or nutrients have important implications for the biosphere. We compare gas and particulate chemistry, including metals, of the substantial magmatic (≥200 kt/day SO2) and lava-seawater interaction (laze) plumes from the 2018 eruption of Kīlauea, Hawai’i. The magmatic plume contains abundant volatile chalcophile metals (e.g. Se), whereas the laze is enriched in seawater components (e.g. Cl), yet Cu concentrations are 105 times higher than seawater. High-temperature speciation modelling of magmatic gases at the lava-air interface emphasises chloride’s critical role in metal/metalloid complexation during degassing. In the laze, concentrations of moderately (Cu, Zn, Ag) to highly volatile (Bi, Cd) metals are elevated above seawater. These metals have an affinity for chloride and are derived from late-stage degassing of distal lavas, potentially facilitated by the HCl gas formed as seawater boils. Understanding these processes yields insights into the environmental impacts of volcanism in the present day and geological past.

“…Heavy metals are metallic elements with atomic density greater than that of water (Fergusson, 1990). The natural origins of heavy metals in the environment are volcanic eruptions and natural crust erosion (Mandon et al, 2019), while anthropogenic activities such as mining are the primary source of metals throughout the world (Ma et al, 2015;Zhu et al, 2017).…”

Due to anthropogenic activity, most vulture species are threatened. Neophron percnopterus, the Egyptian vulture, is a vulture species with a declining population. One of the most important factors threatening the species is exposure to chemicals. The second largest population of this bird species is found in Turkey. Accumulation of heavy metals for this species has not been investigated. The aim of this study was to detect and measure As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn values in the feathers of Neophron percnopterus. Calamis and vane, which are different part of the feathers, were analyzed separately with ICP-OES. According to the results, the mean value of heavy metal accumulation is below the threshold levels, except for Pb (mean ± SD = 32.26 ± 74.71 μg/g d.w.) and Cr (mean ± SD = 17.82 ± 33.74 μg/g d.w.) in vanes. On the other hand, all heavy metal values other than Hg and Zn had critical levels, which may result in lethal and sublethal effects on individuals.
