Volcanic Ash Impacts & Mitigation - Ash toxicity
Under normal winter conditions in New Zealand sheep ingest 260-275 g of soil per day, and sheep foraging for feed covered with ash are likely to take in even more (Cronin et al., 2003). Chronic fluorosis may occur when livestock are exposed to elevated levels of fluorine over the medium to long term (months to years) causing a range of symptoms which impact on livestock welfare and performance.

Fluorine - Periodic table
Fluorspar (which we now know is mainly calcium fluoride) was very useful because it coined with the unwanted parts of metal ores, allowing the pure metal to flow and be collected. The element fluorine had not yet been discovered and the ‘fluor’ in fluorspar came from the Latin word ‘fluere,’ meaning ‘to flow,’ because this is what it allowed metals to do.
