Short summary
The 2011 Puyehue volcano eruption also caused persisting chemical impacts. By 2012, dental fluorosis in deer appeared, with bone fluoride increasing > 38-fold. Livestock also succumbed to fluorosis. As exposure of ruminants continued, bone fluoride reached 10 396 ppm, by 2014 caused skeletal fluorosis, reduced wool growth, and caused major losses among periparturient cattle. Peculiarities of digestive processes make ruminants susceptible to fluoride-containing ashes.
