Diphenylcyanoarsine, also called CLARK 2 (Cyanide-Arsenic Kampfstoff) by the Germans, was discovered in 1918 by Sturniolo and Bellinzoni[1] and shortly thereafter used like the related Clark 1 gas by the Germans for chemical warfare in the First World War. The substance forms colourless, garlic-smelling crystals and causes nausea, vomiting and headaches. It can subsequently lead to e.g. pulmonary oedema (fluid on the lungs).
