Poison
Un article de Wikipédia, l'encyclopédie libre. Ne doit pas être confondu avec Poisson. Les poisons sont, en biologie, des substances qui provoquent des blessures, des maladies ou la mort d'organismes par une réaction chimique, à l'échelle moléculaire. Cette définition exclut les agents physiques, même de petite taille (un caillot, une bulle d'air dans le sang, un courant électrique, une radiation, etc.). Selon l'observation de Paracelse, « Toutes les choses sont poison, et rien n’est sans poison ; seule la dose fait qu’une chose n’est pas un poison. ». On réserve généralement l'appellation de poison à ceux qui agissent à dose très faible (rapport massique inférieur au millième ou au millionième). L'étude des symptômes, des mécanismes d'action, des traitements et du diagnostic des poisons biologiques est appelée la toxicologie. La plupart des espèces produisent des poisons pour elles-mêmes, et s'organisent en conséquence. Grandes catégories de poisons[modifier | modifier le code]

Agatha Christie
Very prolific British author of mystery novels and short stories, creator of Hercule Poirot, the Belgian detective, and Miss Jane Marple. Christie wrote more than 70 detective novels under the surname of her first husband, Colonel Archibald Christie. She also published a series of romances and a children's book. '"And now, messieurs et mesdames," said Poirot rapidly, "I will continue with what I was about to say. Understand this, I mean to arrive at the truth. The truth, however ugly in itself, is always curious and beautiful to seeker after it. Agatha Christie was born in Torquay, in the county of Devon, the daughter of Frederick Alvah Miller, an American with a moderate private income, and Clarissa Boehmer Miller, the daughter of an army Captain. Christie was first educated at home, and at sixteen she was sent to school in Paris, where she studied singing and piano. The Murder of Roger Ackroyd had a great success on the London stage in 1928. Christie's marriage broke up in 1926.
