At first, it seemed like the poisoned russian agent might have ingested thallium in the form of thallium(i) sulfate, a rodenticide (rat poison), not allowed in the us and western countries but still used in other countries. thallium leads to hair loss. it also replaces potassium in important enzymes in the brain, muscles and skin. it takes 8.0 x 102 mg of thallium ion to kill an average adult. it took a bit of investigating to figure out that the agent was actually poisoned by polonium, a radioactive element, harmful only if it goes into the body. the radioactivity emitted by polonium, alpha particles, can be stopped by skin; but, if ingested, it gets into the blood stream, travels to organs and does lots of damage. the maximum safe body amount of polonium is 7 pg (picograms! ) the agent was apparently poisoned with about 10 micrograms. to provide the minimum amount of thallium to kill the average adult, how many ml of 0.45 m solution of thallium(i) sulfate needs to be ingested?

Getting rid of my account might as well do it with some fun make sure to read all of this it is hilarious a plane was about to crash and there were 5 people on board and only 4 parachutes. the first person said: " i am roy keane, one of the best footballers in ireland. i am worth a lot of money and my fans need me so i think i should be saved." the others agreed and gave him one of the parachutes and off he went. the second person said: "i am gerry adams, a radical irish politician who can really my country and i think i should be saved." the others said: "o.k.", and gave him a parachute. the third person said: "i am george bush, president of the most powerful country in the world. everyone knows i am a really nice guy and everyone thinks i am stupid,but i'm not, so i am taking a parachute." and off he went. there were two people left, the pope and a 10 year old schoolgirl. the pope said: "child, i am old and frail and have lived my life while you are young, with everything before you. you take the parachute and i will stay with the aircraft and take my chance." "it's o.k." said the girl, "there are still two bush picked up my schoolbag."
