2. Where does environmental arsenic come from? 2.1 Arsenic is found in the natural environment in some abundance in the Earth’s crust and in small quantities in rock soil water and air. It is present in many different minerals. About one third of the arsenic in the atmosphere comes from natural sources such as volcanoes and the rest comes from man-made sources.

A lot of arsenic was produced here. In the 1870s a handful of mines in Cornwall and Devon produced over half the world's arsenic. It was a by-product 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.

Howeverarsenic prices declined in the 1890s and slumped in 1901: in 1902 the mine closed and most of its buildings were levelled in 1903. In 1915 arsenic mining recommenced to meet shortages in World War I but dressed ore was taken to Cornwall for calcining and refining. After a slump in 1921 work began on the arsenic works in this scheduling.
