Abstract. Volcanic sulfate aerosols play a key role on air quality and climate. However, the oxidation of sulfur dioxide (SO2) precursor gas to sulfate aerosols (SO42−) in volcanic clouds is poorly known, especially in the troposphere. Here we determine the chemical speciation, lifetime and impact on air quality of sulfate aerosols from the 2014–15 Holuhraun flood lava eruption of Bárðarbunga icelandic volcano. To do so, we jointly analyze a set of SO2 observations from satellite (OMPS and IASI) and ground-level measurements from air quality monitoring stations together with, for the first time, high temporal resolution mass spectrometry measurements of Aerosol Chemical Speciation Monitor (ACSM) performed far from the source. We explore month/year-long ACSM data in France from stations in contrasted environments, close and far from industrial sulfur-rich activities. We demonstrate that aged volcanic sulfate aerosols exhibit a distinct chemical fingerprint, with NO3 : SO4 and Organic : SO4 concentration ratios higher than freshly-emitted industrial sulfate but lower than background aerosols in urban/rural conditions. Combining AERONET (AErosol RObotic NETwork) sunphotometric data with ACSM observations, we also show a long persistence over weeks of volcanic sulfate aerosols while SO2 disappears in a few days at most. Finally, gathering 6 month-long datasets from 19 sulfur monitoring stations of the EMEP (European Monitoring and Evaluation Programme) network allows us to demonstrate a much broader large-scale European particulate pollution in SO4 associated to the Holuhraun eruption, from Scandinavia to France. Exploiting these in-situ data, we also show the various rates of SO2 oxidation observed in the volcanic cloud, with SO2 : SO4 concentration ratios ranging in 0.6–7, distinct from background conditions of about 50. Most current studies generally focus on SO2, an unambiguous and more readily measured marker of the volcanic cloud. However, our results here on sulfate aerosols raise fundamental questions about the cumulative impact of tropospheric eruptions on air quality, health, atmospheric composition and climate, which may be significantly underestimated.

The aim of this research was to analyze sugars and phenolics of pollen obtained from 15 different ‘Oblačinska’ sour cherry clones and to assess the chemical fingerprint of this cultivar. Carbohydrate analysis was done using high-performance anion-exchange chromatography (HPAEC) with pulsed amperometric detection (PAD), while polyphenols were analyzed by ultra-high-performance liquid chromatography–diode array detector–tandem mass spectrometry (UHPLC-DAD MS/MS) system. Glucose was the most abundant sugar, followed by fructose and sucrose. Some samples had high level of stress sugars, especially trehalose. Rutin was predominantly polyphenol in a quantity up to 181.12 mg/kg (clone III/9), with chlorogenic acid (up to 59.93 mg/kg in clone III/9) and p-coumaric acid (up to 53.99 mg/kg in clone VIII/1) coming after. According to the principal component analysis (PCA), fructose, maltose, maltotriose, sorbitol, and trehalose were the most important sugars in separating pollen samples. PCA showed splitting off clones VIII/1, IV/8, III/9, and V/P according to the quantity of phenolics and dissimilar profiles. Large differences in chemical composition of studied ‘Oblačinska sour cherry’ clone pollen were shown, proving that it is not a cultivar, but population. Finally, due to the highest level of phenolics, clones IV/8, XV/3, and VIII/1 could be singled out as a promising one for producing functional food and/or in medicinal treatments.
