Arsenic in the Meager Creek hot springs environment, British Columbia, Canada.
TL;DR: Levels of arsenic in water from Meager Creek hot springs, British Columbia, Canada, were found to be naturally elevated, implying that cyanobacteria/bacteria, and possibly green algae are capable of synthesizing arsenosugars from arsenate.

Determination of antimony species with high-performance liquid chromatography using element specific detection
TL;DR: In this paper, anion exchange high-performance liquid chromatography (HPLC) was used for the simultaneous determination of Sb(III) and SbV from organically bounded antimony.

TL;DR: In this paper, it was shown that antimony(III) compounds are biomethylated by Scopulariopsis brevicaulis under aerobic-only growth conditions.

Demethylation of trimethylantimony species in aqueous solution during analysis by hydride generation/gas chromatography with AAS and ICP MS detection
TL;DR: In this article, the use of hydride generation for the speciation of antimony compounds was examined with respect to the problem of molecular rearrangement, specifically, demethylation of trimethylstilbine during the analysis of trimmedethylantimony dichloride (Me3SbCl2) was studied.

Simplex optimisation of conditions for the determination of antimony in environmental samples by using electrothermal atomic absorption spectrometry.
TL;DR: An optimisation procedure utilising the Plackett-Burman method, simplex optimisation and visualisation of the generated response surface via principal components analysis, was carried out for the analysis of the total antimony in plant material.
