DERMATOLOGY BIOLOGICAL WEAPONS -- Discussions In the years 1941-1942, the G.B. makes experiments with anthrax on Scottish islands. Forty years later (1982) Insland Gruinard is still heavily contaminated. Despite all attempts to disinfect the island, the spores of this experiment have led to quarantine them for 48 years, until 1990. In 1986 a specialized company was paid half a million pounds to decontaminate the 520-acre island, scattering on the ground 280 tons of formaldehyde in dilute 2000 tons of seawater. Today if someone dispersed in the atmosphere the anthrax bacteria near a city of 500 thousand inhabitants, could cause the death of over 90 thousand people within a week. "It should be remembered- as says Graham Pearson, University Professor of International Security of Bradford - that biological terrorism is a major threat to our world". The Military laboratories are constantly seeking new poisons with special attention to the world's animal and plant, biological toxins. Examples: Snakes as the cobra, the fish Arothron hispidus, Arothron meleagris or, like frogs Phyllobates aurotaenia, or TARIC Toros, shellfish such as Mytilis californianus, or Conus magus. The Strychnine, is an alkaloid found in small quantities in the seeds of Strychnos nux vomica, a tree indigenous to India, was synthesized in the mid-nineteenth century and produced in large quantities. The Strychnine due to its excitatory properties of the central nervous system, was hired as a drug of abuse, especially among the upper classes of London and Paris. At the beginning of the century was created the first pill for the suicide of secret agents captured by the enemy and contained potassium cyanide, a poison synthesized in 1850. The potassium cyanide, kills after a few minutes and atrocious asphyxiation. In August 1978, the dissident Georgi Markov, Ivan was likely assassinated by Bulgarian secret services in London, with a tiny dart "fired" by a fake and poisoned umbrella (palitossina ). Extracted by a microscopic red algae that populate the coast occasionally called by the natives of Hawaii Limu make or Hana.
