| Year | Risk type | Event type | Agent | Details | Country/location |
|---|---|---|---|---|---|
| 1925 (June 17) | Intentional | International legislation and agreements | The Geneva Protocol is created, with the purpose to prohibit the use of chemical and bacteriological methods of warfare. This protocol marks the first international endeavor to restrict the utilization of biological agents in warfare.[1]:p14[2] | ||
| 1930s | A German scientist created Tabun, the first nerve agent, while attempting to develop a more potent pesticide. The German army weaponized Tabun as a chemical weapon, and it was followed by the development of Sarin and Soman in the late 1930s to early 1940s. American scientists designated these agents as "G" agents, leading to Tabun being labeled GA, Sarin as GB, and Soman as GD. In the 1950s, more stable variants known as the V agents, including VX (Venom X) developed by the British in 1952, emerged. VX, characterized by increased stability, can persist in the environment for several weeks after release.[3]:120-121 | ||||
| 1975 | Intentional | Terrorism (state-sponsored) | Parathion, thallium, multiple | During the Rhodesian conflict, the minority white community in Rhodesia face challenges from native African nationalists. Stretched thin, Rhodesian forces adopt unconventional methods, employing commercially available poisons like parathion and thallium. They contaminate clothing, water sources, and food, resulting in an estimated 1,500–2,500 guerilla deaths, with numerous civilians affected. Facing native African nationalist insurgents, the Rhodesian forces struggled due to limited resources. Rhodesia's chemical warfare, marked by low-tech methods, demonstrate a brutal, yet unconventional approach to counter the growing power of the insurgent forces.[4] | Zimbabwe (Rhodesia) |
| Early 1980s | Intentional | Biological warfare program | Multiple | Project Coast starts operating as South Africa's covert Chemical and Biological Warfare (CBW) program. Operational until early 1990s, the program would be found to have developed lethal chemical and biological weapons, including sterilization toxins and concealed poisons, targeting African National Congress political leaders and black township populations. Project Coast would be accused of contaminating water supplies with cholera, aiding Rhodesian troops with anthrax and cholera, and employing toxic agents for political assassinations. Investigations would lead to dismissals and document destruction, with South Africa officially maintaining the program's defensive nature, despite international concerns.[5] | South Africa |
| 1987 | Around 100 individuals in India fall ill due to the consumption of wheat products contaminated with mycotoxins, a result of heavy rains.<ref name="Melnick">:155 | India | |||
| 1999 | Dioxin affair | Belgium |
