Dorset Biological Warfare Experiments
The Dorset Biological Warfare Experiments were a series of experiments conducted between 1953 and 1975 to determine the extent to which a single ship or aircraft could dispense biological warfare agents over the United Kingdom. The tests were conducted by scientists from Porton Down, initially using zinc cadmium sulfide (ZnCdS) as a simulated agent. Early results showed that one aircraft flying along the coast while spraying its agent could contaminate a target over 100 miles (160 km) away, over an area of 10,000 square miles (26,000 km2). This method of biological warfare–and the test method used to study it–were known as Large Area Coverage (LAC).
In the early 1960s, Porton Down was asked to expand the scope of their tests to determine if using a live bacterium instead of ZnCdS would significantly alter the results. Scientists from the Microbiological Research Establishment at Porton Down selected South Dorset as the site for this next phase of testing, with Bacillus subtilis (also known as Bacillus globigii, or BG) selected as the test agent.[1][2][better source needed] This bacterium was sprayed across South Dorset without the knowledge or consent of the inhabitants.
Background
[edit]Government research into biological warfare tactics first began in the 1910s with the advent of the First World War. The UK and US governments began conducting open-air research experiments during the Second World War.[3]
DICE trials
[edit]The DICE trials took place between 1971 and 1975.[1] Serratia marcescens, along with an anthrax simulant and phenol, were sprayed over Dorset.[1]
At the time, S. marescens was thought to be harmless, but it has since been deemed a human pathogen.[3]
