TL;DR: Characteristics of the Sb soil system are reviewed, with an emphasis on speciation, sorption and phase associations, identifying differences between Sb and As behaviour.

TL;DR: In this study sorption of Sb(V) by two organic rich soils with high levels of oxalate extractable Fe was examined over the pH range of 2.5-7.5 and in two phases mimicking those dominant in the experimental soils, namely a solid humic acid and an amorphous Fe(OH)3.

TL;DR: In this paper, the authors measured soil organic carbon mineralization in macro-aggregates (250-2000μm), micro-aggregate (250−53μm) and the macroaggregate (250 −2000 µm).

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.

TL;DR: A conceptual model is proposed that illustrates the dynamic links between substrate, bacterial diversity, and pore geometry that suggests a structural explanation for differences in bacterial diversity across aggregate sizes.
