Green Cross (chemical warfare) The mixture was chlorine-phosgene, with 95% and 5%. Green Cross (chemical warfare) Green Cross (Grünkreuz) is a World War I chemical warfare pulmonary agent consisting of chloropicrin (PS, Aquinite, Klop), phosgene (CG, Collongite) and/or trichloromethyl chloroformate (Surpalite, Perstoff). Green Cross is also a generic World War I German marking for artillery shells with pulmonary agents (chemical payload affecting the lungs). The tip of the projectile with the fuse end painted green and a green cross at the bottom of the cartridge. Other Green Cross mixtures were based on phosgene and/or diphosgene.

Pyromorphite chemical tests. They were formerly confused under the names green lead ore and brown lead ore ("German: Grünbleierz and Braunbleierz"). The phosphate was first distinguished chemically by M. H. Klaproth in 1784, and it was named pyromorphite by J. F. L. Hausmann in 1813. The name is derived from the Greek for "pyr" (fire) and "morfe" (form) due to its crystallization behavior after being melted. "Paecilomyces javanicus" is a mold collected from a lead-polluted soil that is able to form biominerals of pyromorphite. The color of the mineral is usually some bright shade of green, yellow or brown, and the
