“…The concentrations of toxic metals in ash leachates are not often measured and vary for different volcanoes and eruption style (e.g. Cronin and Sharp 2002;Armienta et al 1998;Cronin et al 1997;Varekamp et al 1984;Hinkley and Smith 1982;Smith et al 1982;Fruchter et al 1980). In vivo studies suggest that transition metals, including Fe, Cu and Ni, in respirable aerosols play a role in inflammatory response of the lung tissues (e.g.…”

Mineralogical analyses and in vitro screening tests for the rapid evaluation of the health hazard of volcanic ash at Rabaul volcano, Papua New Guinea

The continuous ash and gas emissions from the Tavurvur cone in Rabaul caldera, Papua New Guinea, during 2007-08, raised concerns regarding how exposure would affect the respiratory health of nearby populations and impact on the environment. As part of a formal evaluation of the effects of volcanic emissions on public health, we investigated the potential health hazard of the ash using a suite of selected mineralogical analyses and in vitro toxicity screening tests. The trachy-andesitic ash comprised 2.1-6.7 vol.% respirable (sub-4 μm diameter) particles. The crystalline silica content was 1.9-5.0 wt.% cristobalite (in the bulk sample) with trace amounts of quartz and/or tridymite. Scanning electron microscopy showed that the ash particles were angular with sparse, fibre-like particles (∼3-60 μm max. diameter) observed in some samples, which we confirmed to be CaSO 4 (gypsum, at <6 wt.% in the bulk samples) and not asbestiform fibres. The ash specific surface area was low (0.1-2.7 m 2 g −1 ). The leached solution from one of the ash samples was slightly acidic (pH 5.6), but did not contain high levels of toxic metals (such as F, Cu, Zn, Mn, As, Ni and Cd) when compared to previously tested volcanic ash leachates.

“…This methodology was developed based on the capabilities of our laboratory and the compositional range of leachates. It has been tested against the Taylor and Stoiber (1973) and Varekamp et al (1984) methods as reported in Armienta et al (1998), and fulfils all recommendations given by the International Volcanic Health Hazard Network IVHHN (http://www.ivhhn.org/index.php?option= com content&view=article&id=100). In all cases, duplicate samples were analysed and results accepted when differences were less than 10 %.…”

Abstract. Ash emitted by volcanic eruptions, even of moderate magnitude, may affect the environment and the health of humans and animals through different mechanisms at distances significantly larger than those indicated in the volcanic hazard maps. One such mechanism is the high capacity of ash to transport toxic volatiles like fluoride, as soluble condensates on the particles' surface. The mobilization and hazards related to volcanic fluoride are discussed based on the data obtained during the recent activity of Popocatépetl volcano in Central Mexico.
