Application of Chelex-100 and SPR-IDA Resin in Combination with the Optimized Beam Deflection Spectrometry for High-Sensitivity Determination of Iron Species in Sediment Porewater Open
In this work, photothermal beam deflection spectrometry (BDS), combined with a passive sampling technique of diffusive gradients in thin film (DGT), is optimized to improve the method’s sensitivity. The limit of detection (LOD) is then red…

The biogeochemical role of a microbial biofilm in sea ice Open
A paradox is commonly observed in productive sea ice in which an accumulation in the macro-nutrients nitrate and phosphate coincides with an accumulation of autotrophic biomass. This paradox requires a new conceptual understanding of the b…

Determination of Iron in Environmental Water Samples by FIA-TLS Open
The determination of low concentration of iron in natural waters can be difficult due to the complexity of natural water, but primarily because it requires preconcentration of the sample with solvent extraction. In this work we report on r…

Advancing methodology for sub-zero temperature application of DGT technique on sea ice samples for two-dimensional imaging of biogenic metals Open
Ice-associated communities colonize the brine-filled spaces and are exposed to major biogeochemical and physical changes: temperature fluctuations, salinity, dissolved oxygen, light, pH, the surrounding organic matrix, and nutrient stress.…

Determination of Dissolved Iron Redox Species in Freshwater Sediment using DGT Technique Coupled to BDS Open
In this work we have developed a novel method for determination of iron redox species by the use of diffusive gradients in thin-film (DGT) technique coupled to photothermal beam deflection spectroscopy (BDS). The combination of both method…

Mercury presence and speciation in the South Atlantic Ocean along the 40°S transect Open
Mercury (Hg) natural biogeochemical cycle is complex and a significant portion of biological and chemical transformation occurs in the marine environment. To better understand the presence and abundance of Hg species in the remote ocean re…
