Biochar influences soil fertility, N2O emissions, and atmospheric CO2 budgets, because of its quinone aromatic structures, it is redox-active. Here we demonstrate that biochar concentrations 5 10 g L–1 stimulate both the rate extent microbial reduction Fe(III) oxyhydroxide mineral ferrihydrite (15 mM) by Shewanella oneidensis MR-1, while lower (0.5 1 L–1) have a negative effect on reduction. Control experiments showed particles not biochar-derived water-soluble organic compounds are...
Volatile halogenated organic compounds (VOX) contribute to ozone depletion and global warming. There is evidence of natural VOX formation in many environments ranging from forest soils salt lakes. Laboratory studies have suggested that can be chemically stimulated by reactive Fe species while field provided for direct biological (enzymatic) formation. However, the relative contribution abiotic biotic processes budgets still unclear. The goals this study were quantify release sediments a...
Abstract Torrential rain and extreme flooding caused by Atlantic hurricanes mobilize a large pool of organic matter (OM) from coastal forested watersheds in the southeastern United States. However, mobilization toxic metals such as mercury (Hg) that are associated with this vast OM rarely measured. This study aims to assess variations total Hg (THg) methylmercury (MeHg) levels isotopic compositions blackwater river (Waccamaw River, SC, U.S.A.) during two recent events induced Hurricane...
Tropical- and subtropical-storm surges combined with sea level rise cause saltwater intrusions into low-lying coastal ecosystems along the southeastern coast of United States, gradually converting freshwater forested wetland saltmarsh. The transition zone between becomes a degraded wetland, where combination high levels soil organic matter elevated concentrations halide ions creates dynamic biogeochemical environment that may be potential hotspot for halocarbon formation such as chloroform,...
