“…Trimethylarsine has been reported earlier as arising from bacterial cultures. [31][32][33][34][35][36] Dimethylethylarsine has been detected in landfill and sewage gas, 37 natural gas 38 as well as river and harbor sediments. 39 Triethylarsine has been detected under conditions similar to those which give rise to dimethylethylarsine.…”

“…Larsen et al [5] report an LOD of 2.8 g/L for TMAO in urine with an HPLC/ICP-MS-based method; but As(III), As(V), MMA and DMA elute in the void volume and cannot be determined. Odanaka et al [9] applied Purge-and-trap-GC/MS for the determination of As(III)/As(V), MMA, DMA and TMAO in urine. This method cannot discriminate between As(III) and As(V) but yields LODs between 0.2 and 0.4 g/L.…”

“…TMAO does not elute till 63 min after sample injection. Approaches applying gas chromatography for determination of these species in urine cannot discriminate between As(III) and As(V) and suffer from poor detection limits when using small sample volumes [9].…”

“…Der Metabolismus ausgehend von As(V) über As(III), MMAA, DMAA und TMAO bis zum TMA ist für verschiedene Mikroorganismen nachgewiesen [19]. Für Säugetiere wie Mäuse, Ratten und Hamster ist der Metabolismus von verabreichtem As(V) oder DMAA zu TMAO anhand von drei Untersuchungen belegt [20][21][22]. Hier wurden allerdings unphysiologisch hohe Dosen zwischen 1 und 50 mg As/kg Körpergewicht appliziert.…”

“…Für den Menschen ist eine Biomethylierung des DMAA anhand zweier Untersuchungen festgestellt worden [20,21]. Allerdings wurde auch hier mit der Applikation sehr hoher DMAA-Konzentrationen gearbeitet.…”
