On my Sunday Internet wobbles today I came across this article in the Wail. 'Moor Ponies are being fatally poisoned by waste from old tin mines, claims charity as it raises arsenic fears'. People4Ponies are the charity concerned. DEFRA does not agree with their assertions. We all know that there are arsenic hotspots around, but you would usually have to go out of your way to find and be poisoned by them. Perhaps the little chaps are sheltering in a calciner flue somewhere in bad weather and licking the walls.... Any merit to this poisoned ponies claim?
