Trace metals are essential for the growth of anaerobic microorganisms, however, in practice
they are often added to anaerobic digesters in excessive amounts, which can lead to …

Dissolved organic matter (DOM) of sludge is a heterogeneous mixture of high to low
molecular weight organic substances which is including proteinaceous compounds …

The most critical step for methylmercury (MeHg) bioaccumulation in aquatic food webs is
phytoplankton uptake of dissolved MeHg. Dissolved organic matter (DOM) has been known …

This study used semi-continuous laboratory scale biogas reactors to simulate the effects of
trace-element addition in different combinations, while degrading the organic fraction of …

Abstract Addition of Co and Ni often improves the production of biogas during digestion of
organic matter, ie increasing CH 4-production, process stability and substrate utilization …

Mercury (Hg) contaminated sediments can be significant sources of Hg in aquatic
ecosystems and, through re-emission processes, to the atmosphere. Transformation and …

In redox-dynamic environments, sorption to poorly-crystalline, nanometer-sized Fe (III)-
(oxyhydr) oxides like ferrihydrite influences the biogeochemical cycling of nutrients and trace …

Trace nutrients significantly affect the microbial metabolic activity within anaerobic digestion
processes but always imply the risk of overdosing of heavy metals. In this study the …

Dark reduction of Hg (II) to Hg (0) in deep waters, soils and sediments accounts for a large
part of legacy Hg recycling back to the atmosphere. Natural organic matter (NOM) plays a …

Prairie pothole lakes (PPLs) are naturally sulfur-enriched wetlands in the glaciated prairie
region of North America. High sulfate levels and dynamic hydrogeochemistry in combination …
