What kinds of poison gases were used dying World War 1?

Answer 1

Five predominant types of chemical weapons were used by both sides in WW-I. These are as follows:

Tear Gas -- Typically non-lethal, t

ear gas was used in the hopes of clearing part of the battlefield on a temporary basis (which is the main use of chemical weapons). However, neither side was effective at distributing sufficient quantity, and both sides report battles in which the enemy failed to notice the tear gas at all. Tear gas is used as an incapacitating agent today, intended to temporarily blind and inhibit respiration.

Chlorine Gas: Chlorine was moderately effective early in WW-I. Large, highly visible green clouds characterized this weapon. Upon exposure to water, Chlorine gas changes to Hydrochloric Acid (HCL), which can be pretty destructive. However, in the concentrations deliverable at the time, simple wetted cotton pads worked as a viable countermeasure. Also, a lot of chlorine in parts per million was required for a desirable effect. As such, Chlorine gas attacks were only occasionally successful.

Mustard Gas A vesicant, or blistering agent, mustard gas remained effective throughout the war. It typically wasn't lethal, and it was almost never quickly lethal, so it served to injure soldiers and remove them from the battlefield, but not to kill them. The problem with mustard gas was that it sometimes failed to dissipate (up to a month or more), thus denying the gassed area to both the attacking and defending sides.

Phosgene Gas A lung irritant, phogene results in approximately 80% of the toxic gas related deaths in WW-I. Invisible and effective in lower concentrations, phosgene is said to smell like new mown grass or hay in low concentrations, but to be "choking" in higher concentrations. However, phosgene rarely killed quickly, with the majority of deaths resulting from pulmonary edema roughly 24 hours after exposure.

WW-I, sometimes called "The Chemist's War" presents us with a rare historical situation, in that by the time the war ended, both sides had developed countermeasures to the available weaponry. As such, in WW-I, gas, though often used, was not particularly effective.

Chemical attacks in general are hampered by the vagaries of the weather (rain can reduce the effectiveness of some gases; wind can change and blow the toxins back over your own troops), and the general problems that some chemicals present when they do not degrade promptly.

Answer 2

Although many were available from The Great War, and some newer "nerve poisons" related to modern insecticides had been developed, I don't believe that there are any documented cases of the use of poison gas on the battlefield during WW2. The Hitler regime, however, used both carbon monoxide and a nerve poison called Zyclon to exterminate "undesirable" populations: like Polish refugees, mentally and physically challenged people, criminals and psychiatrically disturbed individuals and Jews during the second world war.
Zyklon B was used in gas chambers and the Italians used Mustard gas on Abyssinia and Japanese used Mustard gas on Chinese otherwise it wasn't used
