Diphenylcyanoarsine, also called Clark 2 (Chlor-Arsen-Kampfstoff 2, being the successor of Clark 1) by the Germans, was discovered in 1918 by Sturniolo and Bellinzoni

First World War. The substance causes nausea, vomiting, and headaches. It can subsequently lead to e.g. pulmonary edema

(fluid in the lungs).
