Ten things you probably didn t know about Cornish mining

A lot of arsenic was produced here. In the 1870s, a handful of mines in Cornwall and Devon produced over half the worlds arsenic. It was a byproduct of tin and copper processing and was mainly used in paint, weedkillers and insecticide. It was condensed and collected in long flues or labyrinths, like the one in this photo at Botallack.

Once released, arsenic remains in the environment for a long time. Arsenic is removed from the air by rain, snow, and gradual settling. Once on the ground or in surface water, arsenic can slowly enter ground water. High arsenic levels in private wells may come from certain arsenic containing fertilizers used in the past or industrial waste.
