Mathematical models have been widely applied to perform chemical risk assessments on biological populations for a variety of ecotoxicological pro- cesses. In this paper, by introducing a dose-dependent mortality rate function, we formulate a toxin-dependent aquatic population model that...

Mercury is an air pollutant emitted from coal fired power plants. Once released into the environment, mercury undergoes conversion to organomercury compounds, which cause health concerns for both humans and animals. Many studies have been completed with the goal of reducing mercury emissions...

Huang, Q., Wang, H., Lewis, M.A.
Industrial contaminants are one of the leading causes of pollution worldwide. It has been shown that 13 elements considered priority water pollutants by the US Environmental Protection Agency are present in the Athabasca River and are found in oil sands process-affected water. There are likely...

Influence of forest canopies on the deposition of methylmercury to boreal ecosystem watersheds
DownloadFall 2010
Methylmercury (MeHg) is a potent vertebrate neurotoxin and a contaminant of global concern. Increased anthropogenic emissions of mercury (Hg) to the atmosphere have led to increased bioaccumulation of MeHg in top predatory organisms such as fish, the consumption of which is the main exposure...

Mercury and methylmercury in snowpacks, snowmelt, and tailings ponds of the Athabasca Oil Sands Region, Alberta, Canada
DownloadFall 2017
The Alberta Oil Sands Region (AOSR) is the third largest proven oil reserve in the world and one of Canada’s major economic drivers. Industrialized extraction of this resource has resulted in the release of contaminants from various sources, such as stack emissions, volatilization and leakage of...

This study assessed the geographic distribution of mercury in water, and biota of the Athabasca River, and in snow and vegetation in its watershed. Mercury in the snowpack was significantly elevated within 46km of oil sands development relative to greater distances. Mercury was significantly...
