“…However, since the amount of ash-deposited fluorine is inversely correlated with particle size, and small particles may be carried far away from the vent depending on wind velocity and column height, important amounts of fluoride may be found on soils and vegetation far away from the vent. This behaviour was observed in the eruptions of 30 April 1996 Armienta et al, 2002). Both of these eruptions emitted ash clouds that produced light ashfalls on Mexico City, nearly 70 km NNW of the volcano.…”

“…Although concentration variations with distance have been observed at specific eruptions (Armienta et al, 2002), a general trend cannot be unraveled from the whole dataset. However, since the amount of ash-deposited fluorine is inversely correlated with particle size, and small particles may be carried far away from the vent depending on wind velocity and column height, important amounts of fluoride may be found on soils and vegetation far away from the vent.…”

“…Both of these eruptions emitted ash clouds that produced light ashfalls on Mexico City, nearly 70 km NNW of the volcano. Moreover, a thin ash layer does not hinder grazing and sticks easily to vegetation, leading to a fluorosis hazard to humans and animals at even further distances (Thorarinsson, 1979;Armienta et al, 2002). Whether these amounts of fluoride in ash represent a serious fluorosis hazard to fauna is a question that may not be unequivocally answered from the available information.…”

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.

Atlimeyaya, Puebla is located inside area 1 of the CENAPRED (Prevention Disasters National Center) risk map, which centers on the Popocatepetl volcano. The location of Atlimeyaya shows that it is subjected to significant amounts of ash fall, which strongly impacts all surface water bodies. In this study 9 sites were chosen, which were sampled 5 times during 2014. Collected water samples were analysed for 21 physicochemical parameters and results were compared with Mexican regulations for drinking water. Additionally, the CENAPRED database was searched for volcanic emissions taking place before each sampling event. Statistical analysis was done using Minitab 17, dot plots allowed us to see how chemical concentrations were modified at each sampling event, and how the data are dispersed over the whole concentration range. These results correlated with the number of emission events reported by CENAPRED. Even though most of the chemical parameters allowed us to classify the sampled waters as high quality ones, it is true that the results obtained allowed us to claim that volcanic emissions either as ash or water vapour strongly impact onto surface waters in the following chemical parameters: pH values are between 6.24 and 9.72 units, fluoride range corresponds to 0.1-0.97 ppm, nitrate 0.1-16.2 ppm, nitrite 0-23 ppm, chemical oxygen demand 0-91 ppm, lead 0-0.107 ppm, cadmium 0-0.031 ppm and manganese 0-0.06 ppm.
