Mount Etna is known to release a large amount of Mercury into the environment. Flourine is a danger in the ash of volcanoes in Iceland and New Zealand.
Various scientists measure the amount of mercury released. One estimates that Mt Etna release 2 tonnes per day when erupting. Another estimates 20 tonnes per year.

Volcano gases are mixing from the Iceland volcano with four groundwater springs near the volcano. Hekla cold springs (Iceland): groundwater mixing with magmatic gases.
Mercury in water in of Kagoshima Bay from the underwater Mt. Sakurajima Volcano, Japan. The water above the volcano in the inner bay contains a large amount of Mecury compared to the water at the bay entrance which is farther from the underwater volcano. Soil samples taken from around the bay show that the soil also contains a large amount of mercury from the volcano.

We have analysed the chemical and stable isotope compositions of four spring waters situated just northwest of the Hekla volcano, where cold water emerges from the base of the lava flows. The stable isotope ratios of water (H, O), dissolved inorganic carbon (C) and sulphate (S) were used to determine whether magmatic gases are mixing with the groundwater. The waters can be characterised as Na-HCO(3) type. The results show that deep-seated gases mix with groundwater, substantially affecting the concentration of solutes and the isotopic composition of dissolved carbon and sulphate.
Estimations of mercury fluxes emitted by Mount Etna Volcano

A sampling and measuring device which enables the assessment of atmospheric particulate and gaseous mercury concentrations has been tested on Mount Etna Volcano. Particulate matter is collected on a Whatman GF/C of 1.0 µm pore- size, gaseous mercury species on a Au-column. The analysis is carried out in two steps: (1) the mercury species collected on the filter or the Au-column are transferred to a fixed analytical Au-column; (2) mercury liberated from this column during the second step is detected with a Mercury Vapour Monitor. Average concentrations of gaseous and particulate mercury in ambient sampling sites on Mount Etna are 3.8 ng m-3 and 0.49 ng m-3 respectively. Average concentrations of gaseous and particulate mercury in the plume of Bocca Nuova on Mount Etna are 15 ng m-3 and 24 ng m-3 respectively. An estimation of the total mercury discharge from Mount Etna amounts to 2.5 10-2 tons day-1.

Mercury in the vegetation, soil and atmosphere of Mt.Etna's volcanic area was studied. Mercury contents of pine and spruce needles, brooms, lichens and soil were generally low. Atmospheric gaseous mercury measured at various stations was also low. The role of Mt. Etna as a source of the metal in the Mediterranean basin is also considered.

The mercury levels in the air, aerosol, ash, lava and soil of Mount Etna, determined at the end of the intense eruptive phase of 13 September 1989, are reported.
The concentration values of the metal proved to be comparable to the ones measured during a stationary phase of the volcano.
The contribution of the volcanic activity of Etna to the presence of mercury in the air in the Mediterranean basin was estimated at 20 tonnes per year.

Emissions from volcanoes, fumaroles and solfataras as well as contributions from widespread geological anomalies could represent an important source of mercury released to the atmosphere in the Mediterranean basin. Volcanoes located in this area (Etna, Stromboli and Vulcano) are the most active in Europe; therefore, it is extremely important to know their mercury contributions to the regional atmospheric budget. Two main methods are used for the evaluation of volcanic mercury flux: a direct determination of the flux (by measuring in the plume) and an indirect one derived from the determination of the Hg/SO2 (or Hg/S) ratio value, as SO2 emissions are constantly monitored by volcanologists. An attempt to estimate mercury flux from the Vulcano volcano and to establish the Hg/S ratio value has been made along three field campaigns carried out in October 1998, in February and May 1999 sampling several fumaroles. Traditional sampling methods were used to collect both total Hg and S. The average Hg/S ratio value resulted to be 1.2×10-7. From the Hg/S value we derived the Hg/SO2 value, and by assuming that all the volcanoes located in this area have the same Hg/SO2 ratio, mercury emissions from Vulcano and Stromboli were estimated to be in the range 1.3–5.5 kg/year and 7.3–76.6 kg/year respectively, while for Etna mercury flux ranged from 61.8 to 536.5 kg/year. Data reported in literature appear to be overestimated (Fitzgerald WF. Mercury emission from volcanos. In: 4th International conference on mercury as a global pollutant, August 4–8 1996, Hamburg, Germany), volcanic mercury emission does not constitute the main natural source of the metal.
Mercury distribution in seawater of Kagoshima Bay near the active Volcano, Mt. Sakurajima in Japan.

Kagoshima bay has a highly active volcano in its center. In the filtered seawater and suspended matter collected from 200-m deep fumaroles at the bottom of the inner bay, the geometric mean concentrations of total mercury were 7.6 and 65.0 ng/L, respectively. The surface seawater collected at the inner bay had a higher concentration of mercury when compared to that in the bay entrance (average: 1.0 vs. 0.5 ng/L). In July, however, no such difference was observed. The fumaroles seem to contribute to relatively high concentrations of mercury in the inner bay except in summer, when thermal cline is formed.
Vertical variations in the concentration of mercury in soils around Sakurajima Volcano, Southern Kyushu, Japan. [Sci Total Environ. 2003 Mar 20;304(1-3):221-30]

In an effort to estimate the influence of mercury emitted from Sakurajima Volcano, Southern Kyushu, Japan, on the accumulation of mercury in soil, the vertical distribution of total mercury in soils was investigated together with organic matter content and grain size. The soils were sampled at a thickness of 1 cm from the surface to depth of 1 m at five locations on Sakurajima and two control locations, i.e. Takatoge approximately 11 km southeast and Suzuyama 22 km southwest of the volcano. The concentration in soils increased with the distance from the volcano and was 6.5+/-1.9 ngg(-1) (n=335), 29.0+/-15.6 ngg(-1) (n=100) and 229+/-105 ngg(-1) (n=103) for Sakurajima, Takatoge and Suzuyama, respectively. The concentration of mercury correlated with the amount of organic matter, but not with grain size distribution. The sedimentation rate for Sakurajima, Takatoge and Suzuyama was estimated from geological data to be approximately 1.3, 0.083 and 0.0048 cmyear(-1), respectively. The relatively fast sedimentation of Sakurajima soil was caused by the frequent precipitation of volcanic ash. The annual deposition of mercury estimated for Sakurajima, Takatoge and Suzuyama from the mercury concentration, sedimentation rate and soil density was 9 x 10(4), 3 x 10(4) and 2 x 10(4) ngm(-2)year(-1), respectively. Although the soil of Sakurajima had the lowest concentration among the three sites, it received the largest amount of mercury.
