Effect of dissolved organic matter source and character on microbial Hg methylation in Hg-S-DOM solutions.
Dissolved organic matter (DOM) is a key component of fate and transport models for most metals, including mercury (Hg). Utilizing a suite of diverse DOM isolates, we demonstrated that DOM character, in addition to concentration, influences inorganic Hg (Hg(II)i) bioavailability to Hg-methylating bacteria. Using a model Hg-methylating bacterium, Desulfovibrio desulfuricans ND132, we evaluated Hg...

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Dissolved organic carbon (DOC) and total dissolved amino acids (TDAA) were measured in high (Chukchi Sea) and low (Beaufort Sea) productivity regions of the Western Arctic Ocean to investigate the composition an...

متن کاملA Parallel Simulator for Mercury (Hg) Porosimetry
A parallel simulator, based on the Dual Site-Bond Model of complex media, is developed to study Hg intrusion and extrusion processes in the myriad of voids contained in a porous network. In order to reduce the requirements in RAM and computing resources, the porous network is partitioned into several sub-networks distributed in different cluster processors. The simulator uses shared memory to p...
