Diphenylcyanoarsine even CLARK 2 ( cyanide - arsenic -Kampfstoff) called, was discovered in 1918 by Sturniolo and Bellinzoni and shortly afterwards as the related Clark 1 in the First World War used. The substance forms colorless, garlic-like smelling crystals and causes nausea, vomiting and headaches. Long-term effects are, for example, pulmonary edema .
