| mercury exposure and neurochemical impacts in bald eagles across several great lakes states. | in this study, we assessed mercury (hg) exposure in several tissues (brain, liver, and breast and primary feathers) in bald eagles (haliaeetus leucocephalus) collected from across five great lakes states (iowa, michigan, minnesota, ohio, and wisconsin) between 2002-2010, and assessed relationships between brain hg and neurochemical receptors (nmda and gaba(a)) and enzymes (glutamine synthetase (gs) and glutamic acid decarboxylase (gad)). brain total hg (thg) levels (dry weight basis) averaged 2. ... | 2011 | 21735125 |
