Phosgene was used by the German army from the end of May 1915, when attacks were conducted on the Western Front against French troops and on the Eastern Front on Russians, where 12,000 cylinders with 240–264 long tons (244–268 t) of 95 per cent chlorine and 5 per cent phosgene was discharged on a 7.5 mi (12 km) front at Bolimów.

[25] [26] Phosgene was more potent than chlorine, though some symptoms took 24 hours or more to manifest. Following the extensive use of phosgene during World War I, it was stockpiled by various countries. [27] [28] [29] Phosgene was then only infrequently used by the Imperial Japanese Army against the Chinese during the Second Sino-Japanese ...
Chemical weapons have since washed up on shorelines and been found by fishers, causing injuries and, in some cases, death. Other disposal methods included land burials and incineration. After World War 1, "chemical shells made up 35 percent of French and German ammunition supplies, 25 percent British and 20 percent American". [96]
Traces of a toxic, colorless gas were found at the headquarters of Sweden’s security agency where a suspected gas leak last week forced authorities to evacuate some 500 people from the facility ...
Graph of world population over the past 12,000 years . As a general rule, the confidence of estimates on historical world population decreases for the more distant past. Robust population data exist only for the last two or three centuries. Until the late 18th century, few governments had ever performed an accurate census.
Gases were frequently mixed. For example, white star was the name given to a mixture of equal volumes of chlorine and phosgene, the chlorine helping to spread the denser but more toxic phosgene. Despite the rapid technical developments that occurred in the production of specialised agents, chemical weapons suffered from diminishing ...
In World War I, the U.S. established its own chemical weapons research facility and produced its own chemical munitions. [2] It produced 5,770 metric tons of these weapons, including 1,400 metric tons of phosgene and 175 metric tons of mustard gas. This was about 4% of the total chemical weapons produced for that war and only just over 1% of ...
Widely used during the World War I, the effects of so-called mustard gas, phosgene gas, and others caused lung searing, blindness, death and maiming. During World War II the Nazi regime used a commercial hydrogen cyanide blood agent trade-named Zyklon B to commit industrialised genocide against Jews and other targeted populations in large gas ...
