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 ...
Mercury and methylmercury content in chub from the Svitava and Svratka Rivers at agglomeration Brno
Czech river Leuciscus cephalus methylation methylmercury
2014/3/7
The aim of our study was to determine the total mercury and methylmercury contents in the muscle of indicator fish, to determine the total mercury contents in the sediment, and to evaluate the health ...
Laser light-scattering study of the toxic effects of methylmercury on sperm motility
methylmercury spermatozoa motility Macaca fasicularis laser light-scattering
2009/2/23
An in vitro study was designed using the laser light-scattering technique to obtain further information on the dose-effect relationship of methylmercury on sperm motility. The technique provided a q...
Effects of short-term methylmercury exposure on metallothionein mRNA levels in the testis and epididymis of the rat
short-term methylmercury metallothionein mRNA rat
2009/2/18
Methylmercury (MeHg) is a widespread environmental contaminant that causes reproductive dysfunction in men. Metallothioneins (MTs) are low-molecular-weight proteins that can bind heavy metals and pr...
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. ...
Mercury and methylmercury in muscle tissue of chub from the Elbe River main tributaries
Keywords Leuciscus cephalus mercury/methylmercury ratio risk assessment
2014/3/3
The aim of the present study was to investigate the concentrations of total mercury and methylmercury in muscle of 55 chub (Leuciscus cephalus) from seven main tributaries (Orlice, Chrudimka, Cidlina,...
Rapid determination of methylmercury in fish tissues
gas chromatography ECD capillary column
2014/3/17
The aim of the present study was to develop a rapid and inexpensive method for the determination of methylmercury in fish tissues based on GC/ECD instrumentation. The new method is based on acidic dig...
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...
