A blood agent (also called a cyanogen agent) is a compound that prevents the normal transfer of oxygen from the blood to the body tissues, resulting in chemical asphyxiation.
One of the earliest reactions to the use of chemical agents was from Rome.
There are many reports of the isolated use of chemical agents in individual battles or sieges, but there was no true tradition of their use outside of incendiaries and smoke.

Chromium in the form of its salts may be estimated quantitatively by precipitation from boiling solutions with a slight excess of ammonia, and boiling until the free ammonia is nearly all expelled.
Chromium trioxide, Cr0,, is obtained by adding concentrated sulphuric acid to a cold saturated solution of potassium bichromate, when it separates in long red needles; the mother liquor is drained off and the crystals are washed with concentrated nitric acid, the excess of which is removed by means of a current of dry air.
Cyanogen compounds of chromium, analogous to those of iron, have been prepared; thus potassium chromocyanide, K4Cr(CN)s.2H5O, is formed from potassium cyanide and chromousacetate; on exposure to air it is converted into the chromicyanide,K3Cr(CN)6, which can also be prepared by adding chromic acetate solution to boiling potassium cyanidesolution.

Cyanogen chloride is nonpersistent, and decontamination may be accomplished by allowing sufficient time for the agent to evaporate while monitoring vapor concentrations and restricting access to avoid producing a hazardous situation.

Nerve agents are clear, colorless liquids with no perceivable odor (although two are said to have a slight odor, this is not a reliable detection method).
Blood cholinesterase is generally inhibited, or depressed, after exposure to a nerve agent, except that a small amount of vapor affecting the eyes, nose, and airways may or may not be absorbed to cause this inhibition.
The former military agent BZ (now used in pharmacology where it is known as QNB) is a cholinergic blocking compound and produces many effects similar to those of atropine, such as mydriasis, drying of secretions, heart rate changes, and decreased intestinal motility.

In contrast, inhaled cyanide produces systemic effects and was thought to be carried in the blood; hence the term "blood agent." The widespread distribution of absorbed nerve agents and vesicants via the blood invalidates this term as a specific designator for cyanide.
Cyanogen chloride is also similar to the riot-control agents in causing irritation to the eyes, nose, and airways, as well as marked lacrimation, rhinorrhea, and bronchosecretions.
First, a methemoglobin-forming agent such as amyl nitrite (available in civilian antidote kits, but not in military kits, as crushable ampoules for inhalation) or sodium nitrite (for IV use) is administered, since the ferric ion (Fe) in methemoglobin has an even higher affinity for cyanide than does cytochrome a3.

The employment of biological agents in a "cocktail" mix with chemical warfare agents is consistent with Soviet military doctrine.
It is also probable that biological agents would be used in heavy concentrations to insure a high percentage of infection in the target area The use of such concentrations could result in the breakdown of individual immunity because the large number of in micro-organisms entering the body could overwhelm the natural body defenses.

The general symptoms of nerve agent exposure in order are: running nose, tightness of chest, dimness in vision and contraction of the pupils of the eye to pinpoints, difficulty in breathing, drooling and excessive sweating, nausea, vomiting, cramps, involuntary defecation and urination, twitching, jerking and staggering, headache, confusion, drowsiness, coma and convulsion.
Incapacitating chemical agents are intended to produce physiological or mental effects that prevent exposed military personnel from performing their duties for significant periods of time.
One such agent is BZ, which produces a variety of symptoms, including restlessness, dizziness or giddiness, failure to obey orders, confusion, loss of memory, erratic behavior, stumbling or staggering, vomiting, slurred or nonsensical speech, hallucinatory behavior, disrobing, mumbling, stupor and coma.

VG (also called Amiton or Tetram) is a "V-series" nerve agent closely related to the better-known VX nerve gas.
It is commonly theorized that the so called "second-generation" V series agents came from a cold war era Russian chemical weapons development program.
They have similar lethal dose levels to VX (between 10-50 mg) and have similar symptoms and method of action to other nerve agents that act on cholinesterase, and treatment remains the same, but the window for effectively treating second generation V series seizures is shorter.

Blood gas is an inhaled agent that can be smelled; however, it takes effect in humans in less than 6 minutes and causes convulsions and suffocation, as all blood gases do because they interfere with the absorption of oxygen by the blood in the lungs.
This was known as one of the first modern warfare chemical agents and was responsible for almost 80 percent of the fatalities in World War I where the gas was used.
Although this agent is nonlethal, it is able to render soldiers totally helpless and is used very often on the battlefield as a harassing agent.

 CHEMICAL WARFARE IN BOSNIA?
Before the breakup of Yugoslavia in 1991, the JNA’s chemical weapons program produced the nerve agent sarin, the blister agent sulfur mustard, the psychochemical incapacitant BZ, and the irritants CS and CN, and turned these chemical agents into weapons.
In addition, the JNA also produced the choking agent phosgene, the psychochemical incapacitant LSD-25, and the irritant chloropicrin, and experimented with laboratory quantities of the nerve agents soman, tabun and VX, the blister agents nitrogen mustard and lewisite, and the blood agent cyanogen chloride.
Several sources indicate that the JNA continued to experiment with incapacitating agents during the 1980s, and it appears that at some point it started filling 82mm and 120mm mortar shells with BZ.

Background: Cyanogen chloride (North Atlantic Treaty Organization [NATO] designation CK) is one of two volatile cyanide military chemical warfare agents.
These agents first were used in large quantities by the French and British during World War I. While the United States maintained 500-pound and 1000-pound CK bombs, these were not used during World War II.
More recently, Iraq is suspected to have used a cyanide-like agent against the Kurds in the 1980s.
