TL;DR: In this paper, the authors investigated the bioaccumulation and uptake of antimony in a highly contaminated stream near the Hillgrove antimony-gold mine in NSW, Australia, and reports high Sb (and As) concentrations in many components of the ecosystem consisting of three trophic levels, but limited uptake into aboveground parts of riparian vegetation.
Journal ArticleDOI
A microwave-assisted sequential extraction of water and dilute acid soluble arsenic species from marine plant and animal tissues
TL;DR: A sequential extraction technique was developed where the previously methanol-water extracted pellet was further extracted with 2% (v/v) HNO(3) under the optimised conditions, and increases in arsenic recoveries between 13% and 36% were found.
Journal ArticleDOI
Uptake and metabolism of arsenate by anexic cultures of the microalgae Dunaliella tertiolecta and Phaeodactylum tricornutum
TL;DR: The results show that at natural seawater arsenic concentrations, both algae take up substantial amounts of inorganic arsenic that is complexed with structural elements or sequestered in vacuoles as stable complexes.

Contribution of Arsenic Species in Unicellular Algae to the Cycling of Arsenic in Marine Ecosystems
TL;DR: The hypothesis that arsenobetaine (AB) is formed in marine animals via the ingestion and further metabolism of arsenoribosides is supported, and the observation of significant DMAE concentrations in some unicellular algal cultures suggests that un icellular algae-based detritus contains arsenic species that can be further metabolized to form AB in higher marine organisms.
