It was during World War I (WWI) that modern military chemical warfare emerged. Once immersed in that “Great Conflict,” the United States’ need for chemical warfare research became a priority and the U.S. Chemical Warfare Service (CWS) was established. (For more information, see Featured Article Chemical Warfare in World War I.) The need for research chemists quickly grew, and, before the war’s end, more than 10 percent of all chemists in the United States become involved in this effort.

"It was Thursday evening, April 22, 1915. . . . As we gazed in the direction of the bombardment, where our line joined the French, six miles away, we could see in the failing light the flash of shrapnel with here and there the light of a rocket. But more curious than anything was a low cloud of yellow-grey smoke or vapour, and, underlying everything, a dull confused murmuring. Suddenly down the road from the Yser Canal came a galloping team of horses, the riders goading on their mounts in a frenzied way; then another and another, till the road became a seething mass with a pall of dust over all. Plainly something terrible was happening. . . ."

Toxic Industrial Chemicals and the CWC
![]() Highly Toxic Chemical |
The Chemical Weapons Convention (CWC) prohibits the development, production, stockpiling, or transfer of toxic chemicals intended for use as chemical weapons. At the same time, the Convention also protects the rights of States Parties to develop, produce, store, and transfer toxic chemicals intended for peaceful purposes. This article examines the measures in place within the CWC to accomplish both of these objectives. [Full Story]

Emerging Dual-Use Technologies
Biological research conducted for defensive purposes relies on the same scientific principles and technology that could be used to develop offensive biological weapons. The difference between peaceful and hostile use of any technology, process, or instrument is that of intent, which is difficult, if not impossible, to measure. This dual-use phenomenon presents unique problems for balancing scientific advancement against measures to prevent the development of biological weapons. [Full Story]

Hydrolysate: Wastewater Byproduct of CW Neutralization
![]() Hydrolysate: Wastewater Byproduct of CW Neutralization |
Hydrolysate is a wastewater byproduct of a chemical agent neutralization process called caustic hydrolysis. This technology was developed as an alternative to incineration as a means for destroying chemical weapons. However, the caustic byproduct, hydrolysate, produced by hydrolysis must also be eliminated.
Currently, the Army has elected to transport hydrolysate waste to off-site facilities for final treatment. [Full Story]

On March 20, 1995, during morning rush hour, five men entered different trains on the Tokyo subway system, each carrying two or three plastic bags covered with newspapers. At a given time, the men removed the newspapers and punctured the bags using sharpened umbrella tips, and quickly exited the trains. As the liquid from the packages spread and evaporated into the air of the subway trains, people began to cough, choke, convulse, and collapse. By the end of the day, twelve people were dead, and almost 4,000 people were injured.

In the early 1930s, a German company called I. G. Farbenindustrie began investigating chemical compounds called organophosphates for potential use as insecticides. In December 1936, Dr. Gerhard Schrader, who headed this research effort for the company, synthesized a highly toxic organophosphate that would later be given the name Tabun. Over a year later, he synthesized a second organophosphorous compound that he called Sarin. [Full Story]

Yellow Rain
![]() Bee droppings, resembling yellow rain |
1975, following the Vietnam War, the communist governments of Vietnam and Laos launched a retaliatory campaign against Hmong tribesmen in northern Laos, who had sided with the United States during the war and continued to resist communist rule. That summer, reports came from Laos claiming that government forces were using Soviet-supplied chemical weapons to drive the Hmong out of their mountain hideaways. Refugees reported that toxic agents were being delivered by low-flying aircraft; most described an oily, yellow liquid that sounded like rain when it struck leaves or roofs, earning it the nickname "yellow rain."

Toxins
![]() Castor plant: Ricinus communis |
Toxins are poisonous biochemicals that are produced by living organisms. Toxins are distinct from other chemical agents in that they are more structurally complex and are naturally occurring (although a few toxins can be synthetically produced in laboratories). Unlike other types of biological agents—bacteria, viruses, fungi, and plants—toxins are not living organisms. This is significant in that toxins do not self-reproduce, and do not respond to antibiotic drugs. Because of their unique characteristics, toxins are prohibited by both the Chemical Weapons Convention (CWC) and the Biological Weapons Convention (BWC). [Full Story]

Foot and Mouth Disease Virus
Since the beginning of August, around 2,000 cows in the United Kingdom have died as a result of foot-and-mouth disease (FMD). Trade restrictions have caused significant losses to the British meat industry. The current outbreak is small in scale compared to an earlier outbreak in 2001, in which over six million animals died and which cost the country an estimated £4 billion (around $6.4 billion). In both instances, the animals did not die from infection, but were killed in order to prevent further spread of the disease. FMD is considered the most economically devastating livestock disease in the world, and the virus that causes it could potentially be used as a weapon of agroterrorism. [Full Story]

BWC Sixth Review Conference
Last December, the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on Their Destruction, more commonly known as the Biological Weapons Convention (BWC), held its Sixth Review Conference (RevCon) in Geneva. The three week meeting ran from November 20 to December 8, 2006, and was considered to be a moderately successful RevCon. The States Parties reached consensus on a number of key issues. These included: a new intersessional work program; creating an implementation support unit; promoting confidence building measures (CBMs), and promoting universalization of the Convention.

Tularemia
Last fall, biohazard sensors on the Mall in Washington, D.C. detected low levels of the bacteria Francisella tularensis which causes tularemia. Although these levels were too low to be a health threat to the public, authorities were still notified in order to be on the outlook for possible cases. The presence of the bacteria was not deemed intentional; the detection of it was suspected to have been due to environmental factors.1 This incident highlights F. tularensis and its possible use as a biological weapon.

Sarin
Last month an artillery shell containing sarin exploded in Iraq, exposing several U.S. troops to this deadly chemical. The bomb is believed to have been left over from the Iran-Iraq war, but since it was unmarked, it is not known whether the attackers knew the bomb contained sarin. This incident brings into focus a potent chemical weapon that has been, and continues to be, pursued for nefarious reasons.

The Siege of Caffa
The siege of the Crimean city of Caffa in 1346 CE by invading Mongol hordes is often cited as the most important and recognizable among the first recorded incidents of biological warfare—and the primary cause of the spread of the plague to Europe.
The city of Caffa (now Feodosija, Ukraine), established in 1266 CE by agreement with the Mongols on the Black Sea, was an important trading hub between Genoa and the Far East. In 1289 CE the city fell under the suzerainty of the Khan of the Golden Horde. [Full Story]

Deadly Legacy: Japanese ACW in China
Japanese scientists began to develop chemical weapons in 1917. By World War II, the Japanese Imperial Army had a chemical weapons arsenal of five to seven million munitions, containing phosgene, mustard, lewisite, hydrogen cyanide, and diphenyl cyanarsine. [Japan color-coded its chemical weapons shells.

Binary Chemical Munitions: U.S. and Chinese Notional Designs
Compared to traditional unitary chemical ordnance, binary chemical weapons have been traditionally viewed with having advantages in terms of logistical safety in their handling. About 20 years ago during the Cold War, the United States invested large sums of money and effort into developing binary chemical weapons as part of a modernization program. It also appears that the Chinese military also seriously considered the idea of developing its own binary weapons, including a rocket for a multiple launch rocket system (MLRS). Due to per unit cost and other factors, however, it is not likely that China produced any of these in quantity.... [Full Story]

Early Use of Chemical Weapons in Warfare
In the form of poisoned arrows, toxic roots and even windblown dirt, chemical weapons have been in use for thousands of years. As early as 590 B.C., Solon of Athens is said to have used hellebore roots (a purgative) to poison a water aqueduct during the siege of Cirrha, and later on, the ancient Chinese, Romans, and Greeks employed their own chemical warfare tactics and agents. Although crude by today's standards, early chemical weapons were nonetheless effective enough to play a valuable role in warfare throughout the course of history. [Full Story]
