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]
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.
Chemical warfare (CW) involves using the toxic properties of chemical substances as weapons. [1] [2] This type of warfare is distinct from nuclear warfare, biological warfare and radiological warfare, which together make up CBRN, the military acronym for chemical, biological, radiological, and nuclear (warfare or weapons), all of which are considered "weapons of mass destruction" (WMDs), a ...

After launching a research effort in the 1970s, Iraq was able to use chemical weapons in their war against Iran and to kill large numbers of their own Kurdish population in the 1980s. On June 28, 1987, in Sardasht , during two separate attacks on four residential areas, an estimated as 10 civilians were killed and 650 civilians injured. [ 16 ]
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 ...
