According to the available data, the 2010-2012 survey of the land where army units and military bases stationed showed that more than 40 places were seriously polluted by carcinogen causing leukemia, skin diseases, etc.

Poisonous material exceeded the tolerance value 20 times at a unit of the 27th Division of the puppet army and ten times at a unit of the 12th Division of the army.

Carcinogen detected in the land around the firing range of the puppet army far exceeded the tolerance limit.

This fact is sparking off serious concerns in south Korean society.
