Ueber die Einwirkung von Schimmelpilzen auf Arsen und seine Verbindungen

Biological Methylation.

“…Even on the assumption that sodium methanesulfonate escaped detection in the sulfite cultures, it is difficult to explain the non-formation of ethyl methyl sulfone from sodium ethanesulfinate. (4) Methylation of nitrogen compounds Coordination of a positive methyl ion would also explain the well-known conversion of pyridine and quinoline to methylpyridinium and methylquinolinium hydroxides in the body of the dog (126,145,200).…”

“…The earliest and most obvious explanation put forward to explain the absorption of arsenic by persons living in the rooms was the inhalation of particles detached from the paper. The presence of arsenic in the dust of such rooms had been demonstrated (for references see Abel and Buttenberg (4) and Huss (136)), but poisoning had also been observed where the original arsenical paper had been covered by a fresh one containing no arsenic (Fleck (86); see also Huss). Consequently it was necessary to look for some other cause than mechanical disintegration of the pigment.…”

Zur Kenntnis der biologischen Zersetzung von Arsenverbindungen

“…Jahrhunderts der Gedanke aufgeworfen wurde, dab das Freiwerden des Arsens aus Tapeten mit biologischen Prozessen verbunden write. In der Carlsruher Zeitung vom ~ovember 18B9 f~uBert n~mlich Gmelin (2) seine Ansicht dahin, dab in feuchten, gegen Norden gelegenen Wohnungen, deren Wande mit arsenhaltigen Tapeten bekleidet sind, flfichtige hrsenverbindungen dutch die Vergarung der organischen Substanz gebildet werden. Gmelin machte aueh die Beobaehtung, dab die Luft in solchen Wohnungen einen an Knoblauch erinnernden "Geruch besa•.…”

The toxicity of trimethylarsine: an urban myth

“…Similarly, Abel and Buttenberg in Germany had found little or no problems for mice exposed to the gas for 5 h. 29 One of these investigators had experienced some disturbances (dizziness, sickness) when working with the fungal cultures, as did Gosio, but other collaborators did not. These early toxicological studies were obviously imprecise since it was difficult to separate out the actions of the arsenical gas and carbon dioxide.…”
