Japan's WWII Chemical Weapons

From the June 9, 2014, Chemistry World "Explosive end for Japan's Second World War chemical weapons": by Nina Notman.

As Japanese forces retreated in China near the end of the  war, tens of thousands of chemical weapons were left behind.  Today, major progress is being made to round them up and destroy them.  They are still responsible for killing Chinese people today.More than 50,000 projectiles, mortars, aerial bombs, liquid-filled drums and gas-filled pots containing chemical agents such as sulfur mustard, lewisite and phosgene have been found in 50 sites in China so far.

Due to their age. their deterioration have cause some 2000 injuries and even fatalities.

It is estimated that the Japanese used chemical weapons 2000 times between 1937 and 1945.
