Photodecomposition of Methylmercury in Atmospheric Waters
Cloud Fog Rain Formation Methylmercury
2016/3/28
Experiments were conducted to empirically examine net changes in methylmercury concentration of atmospheric waters
as function of irradiance. Methods were developed to allow experiments to be conduct...
Mercury and methylmercury cycling in sediments of the mid-Atlantic continental shelf and slope
Mercury methylmercury cycling slope
2014/4/17
We present a detailed study of the biogeochemical factors controlling mercury (Hg) distribution,
methylmercury (MeHg) production, and MeHg efflux in sediments of the mid-Atlantic continental shelf an...
The origin of methylmercury in open Mediterranean waters
The origin of methylmercury open Mediterranean waters
2014/4/18
We present high-resolution vertical profiles of methylated mercury (MeHgT = monomethylmercury + dimethylmercury) concentrations in the water column of the open and marginal areas of the Mediterranean ...
Controls on the fate and transport of methylmercury in a boreal headwater catchment, northwestern Ontario, Canada
methylmercury methylation hydrology boreal catchment
2009/3/17
The fate and transport of methylmercury (MeHg) were studied in a small boreal catchment. Hydrological processes largely govern the magnitude of the flux of MeHg. Seasonal and inter-annual variability ...
The methylmercury cycle in Little Rock Lake during experimental acidification and recovery
The methylmercury cycle Little Rock Lake
2014/4/23
The cycle of waterborne methylmercury (meHg) in Little Rock Lake is characterized by a period of accumulation
during summertime (when the lake is warm and open to the atmosphere) and a period of decl...
Methylmercury cycling in estuarine sediment pore waters (Penobscot River estuary, Maine, USA)
Methylmercury cycling estuarine sediment pore waters
2014/4/21
Particulate mercury (Hg) sequestered in coastal marine sediments may be efficiently methylated to highly toxic methylmercury (MeHg), thereby placing exposed organisms at risk of MeHg bioaccumulation. ...
Thiols in wetland interstitial waters and their role in mercury and methylmercury speciation
wetland interstitial waters their role in mercury methylmercury speciation
2014/5/19
Organic sulfhydryl compounds, or thiols, are ligands that strongly complex class B metals such as Hg and methylmercury (MeHg). We determined the concentration profiles of five low-molecular-weight thi...
Fluxes of methylmercury to the water column of a drainage lake: The relative importance of internal and external sources
Fluxes of methylmercury water column of a drainage lake The relative importance internal and external sources
2014/6/9
We studied fluxes of methylmercury (MeHg) through a Precambrian Shield lake using a mass balance approach. The primary goal of the study was to determine the importance of various sources of MeHg to t...
