Numerous Canadian scientific studies show that such impoundments cause a several-fold increase in mercury in fish—the result of high mercury release and accelerated transformation of the element to highly toxic and biomagnified methyl mercury in flooded soils and vegetation. Others developed shaking (tremors) in their arms and legs, difficulty walking, and even brain damage. Nabi, Shabnum (2014).
