Mercury in fish thesis

Elevated levels of methyl-mercury Hg , a potent neurotoxin, in fish are found in many lakes worldwide. The findings of my study were significant because, at the time, it was not clear whether proposals to reduce Hg emissions from coal-fired power plants would lower methyl-Hg levels in fish. To better understand the effects of Hg emission reductions, I simulated different rates of atmospheric Hg deposition in large, in-lake mesocosms at the Experimental Lakes Area, Ontario. I added inorganic Hg highly enriched with a stable isotope, which allowed me to track its environmental fate and bioaccumulation.

Mariah Shannon Taylor , Syracuse University. Mercury contamination within aquatic ecosystems is a concern in the Adirondack Park of New York State due to mercury deposition from global and regional atmospheric sources coupled with watershed characteristics that drive biophysical processes which mobilize and transform mercury, increasing its bioavailability. Short-term internal biological forces also impact mercury bioaccumulation as fish communities and populations change due to species introductions and lake management practices causing alterations in food web structure and energy transfer. Little Moose Lake, located in the southwestern region of the Adirondacks, provides an opportunity to study how shifts in food web dynamics may impact biological cycling of mercury. To promote the native Lake Trout fishery in Little Moose Lake, large-scale annual removal of non-native Smallmouth Bass has been utilized as a management strategy for over 15 years. Mercury concentrations in Lake Trout have increased over the year period, while Smallmouth Bass mercury concentrations decreased over the same interval.

Scientific studies seldom go completely as planned. There can be twists and turns along the way. Or fires, in Erin N.

Expectant mothers and parents of young children know to limit certain seafood intake to avoid high levels of mercury. Just how is mercury winding up in the fish on your plate? And why should it be avoided? But human activities have increased total mercury concentrations in the atmosphere by about percent above natural levels — to dangerous levels for humans if it ends up in their systems in the wrong way.
