Katharina Wurm (8C) erhielt für Ihre VWA aus dem Fachbereich Chemie mit dem Titel "Ausgewählte Gifte und ihre Darstellung in Romanen von Agatha Christie Blausäure, Arsen und Strychnin" den Ehrenpreis der Gesellschaft Österreichischer Chemiker.

Wir gratulieren herzlich!

Abstract der VWA:

Agatha Christie has always been known for her remarkable expertise in and use of chemistry in her novels–cyanide, arsenic and strychnine being among her signature poisons.In this work,the different forms of thesesubstancesalong with their effects are described and compared totheir portrayalsin Christie’s storiesas to assess whether her depictionsare accurate. Procurements and detection methodsare addressed as well.The term “cyanide” includes all chemical compounds containing either a cyanide residue (–CN) or a cyanide ion (CN-). In the body, these compounds release hydrogen cyanide (HCN), which interruptsthe electron transport chain. Christieaccurately describedthe symptoms, apart from falsely includingcyanose.Arsenic (As) can be found in form of variousions orcompounds, such as arsenic(III)oxide(As2O3). Several mechanisms in the human body can be affected, thus causing differentsymptoms. In one novel, the author remarkedthat arsenic binds to sulphur atoms in nails but ignoredthat it only does so in the nail root.Strychnine (C21H22N2O2) is a plant alkaloid, often occurringin the form of more hydrophilic strychnine salts. Inthe central nervoussystem, strychnine avertsthe inhibitory function of glycine –meaning that any stimuliwill make muscles contract. Agatha Christie factually illustrated the tetanic bridging position of the spasming victim.Moreover, she probably carried out an experiment to support a reaction featured in the same story.
