"Ricin is not infectious between people and the risk to the wider public based on the information available has always been low," Renu Bindra from the UK Health Security Agency (HSA) told reporters.
Ricin (/ ˈ r aɪ s ɪ n / RY-sin) is a lectin (a carbohydrate-binding protein) and a highly potent toxin produced in the seeds of the castor oil plant, Ricinus communis.The median lethal dose (LD 50) of ricin for mice is around 22 micrograms per kilogram of body weight via intraperitoneal injection.
During the raid on the homes of a man and son in June 2009, a very small amount of ricin was allegedly found in a sealed jam jar kept in a kitchen cupboard. A father and son, Ian and Nicky Davison were arrested under the 2000 Terrorism Act. The arrests followed a long-running intelligence-led operation against extreme right-wing activity. [27]
There was no ricin with which to poison London, only notes and 22 castor seeds. There was no one who even knew how to purify ricin. [3] On 17 August 2006, former British ambassador to Uzbekistan Craig Murray summed up: I spoke at the annual Stop the War conference a couple of months ago [and] referred to the famous ricin plot...
There seems little reason for Abu Musab al-Zarqawi to move into Pankisi Gorge, which is remote from Middle Eastern operational environments. [4] In the build-up to the Iraq War in early 2003, dozens of North Africans (mainly Algerians) were arrested in the United Kingdom, France and Spain on charges of preparing ricin and other chemical weapons.
According to the Guinness World Records, this is the world's most poisonous common plant. [22] If ricin is ingested, symptoms commonly begin within two to four hours, but may be delayed by up to 36 hours. These include a burning sensation in mouth and throat, abdominal pain, purging and bloody diarrhea.
Eventually, tea drinking became so popular in England that now it's hard to imagine British people doing anything other than politely enjoying their Earl Grey. So, you have Portugal to thank the ...
Is the density of ricin so low that a pinhead-sized amount (I assume on the order of 10^-9 m^3) weighs only 0.5 mg? Or does this refer to a different delivery mechanism than injection or inhalation? "Ricin is 6 billion times more toxic than cyanide and 12 billion times more poisonous than rattlesnake venom by weight." This seems very unlikely.
