Bromine in soils and peats

Spatial variation in natural formation of chloroform in the soils of four coniferous forests

“…This is well in line with previously published data on bromine and iodine speciation in soil (Maw and Kempton 1982) and probably reflects the preference of the halogenating enzymes for bromine and iodine, which both have a lower oxidation potential than chlorine (Sheng and Gold 1997). Comparing with the literature, our findings of *600 lg TOCl g -1 SOM and an additional *100 lg TOBr ?…”

Bromine species fluxes from Lake Constance’s catchment, and a preliminary lake mass balance

“…12). This is consistent with most bromine in soils being associated with organic matter and incorporation of bromine into organic material by lake organisms (Yamada, 1968;Maw and Kempton, 1982;Hü tteroth et al, 2007). During the summer, carbonate bound bromine contributes to a significant degree, and in some cases is the dominant particulate bromine carrier.…”

Changes in biomass burning mark the onset of an ENSO-influenced climate regime at 42°S in southwest Tasmania, Australia

“…Organic carbon has (Saez et al, 2009;Burnett et al, 2011;Liu et al, 2013;Gadd et al, in press), validating the use of this proxy for sediment organic matter content. Further, bromine (Br) has been found to be a reliable proxy for organic matter content in both lacustrine and oceanic sediments (Phedorin et al, 2000;Croudace et al, 2006;Ziegler et al, 2008;Hahn et al, 2014) and Br content is significantly higher in organosols (the dominant soil type in southwest Tasmania) than in other soil types (Maw and Kempton, 1982), thus, providing an additional proxy for sediment organic matter content.…”

“…No data modification was performed prior to the PCA. The PCA was performed using PC-Ord for Windows version 4.27 (McCune and Mefford, 1999). Ratios of incoherent and coherent scattering measurements (Mo Inc/Coh) produced by the core scanner were used to determine the average atomic number of material in the sediment, which is a proxy for organic matter content (e.g.…”
