7. Gruinard Island
In the Second World War, the British government decided to test anthrax as a bioweapon and compulsorily purchased Gruinard Island from its owners for use as a testing site. The island, part of Scotland, remained contaminated with anthrax for decades – at least until 1986, when 280 tonnes of formaldehyde were sprayed on the island to kill the spores.
