Porton Down Biological Warfare on the public

During the Cold War, the British Government used the general public as unwitting biological and chemical warfare guinea pigs on a much greater scale than previously thought, according to new historical research.In more than 750 secret operations, hundreds of thousands of ordinary Britons were subjected to ‘mock’ biological and chemical warfare attacks launched from aircraft, ships and road vehicles.Up until now historians had thought that such operations had been much less extensive. The new research, carried out by Ulf Schmidt, Professor of Modern History at the University of Kent, has revealed that British military aircraft dropped thousands of kilos of a chemical of ‘largely unknown toxic potential’ on British civilian populations in and around Salisbury in Wiltshire, Cardington in Bedfordshire and Norwich in Norfolk.Substantial quantities were also dispersed across parts of the English Channel and the North Sea. It’s not known the extent to which coastal towns in England and France were affected.
The research reveals, for the first time, that around 4600 kilos of the chemical, zinc cadmium sulphide (now thought to be potentially carcinogenic, on account of its cadmium content) were dispersed from ships, aircraft and moving lorries between 1953 and 1964.The secret operation – carried out by scientists from the government’s chemical and biological warfare research centre at Porton Down, Wiltshire - involved the release of large quantities of bacteria called Bacillus globigii. The scientists were keen to discover whether ‘long distance travel of aerosols’ in the tube network ‘was due to transportation within trains’ or through the tube’s air ventilation systems.
