抛射物

To the 19th century, some European countries have been able to industrial production of highly toxic substances to poison a large number of possible for the war, and aroused attention of the media .1899 proposed Declaration of the Hague Conference to prohibit the use of asphyxiating and releasing toxic gas projectiles .1907 for the sole purpose of the second Hague Conference, in the annex to the resolution of Marine regulations, once again states:"In particular, prohibit the use of poison or poison weapons facilities."

到19世纪末，欧洲一些国家已能工业生产剧毒物质，使毒物大量用于战争成为可能，并引起社会舆论的关注。1899年海牙会议宣言提出，禁止使用以施放窒息性和中毒性气体为唯一目的抛射物。1907年第二次海牙会议，在有关陆战法规的决议附件中，再次规定：&尤其禁止使用毒物或施毒武器。&
