Ambient particulate matter (PM) samples were collected on quartz filters at a rural site in central Ontario during an intensive study in 2007. The concentrations of organic carbon (OC), pyrolysis orga...
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 ...
