Mercury is ubiquitous in the environment, and in our mouths in the form of "silver" amalgams. Once introduced to the body through food or vapor, mercury is rapidly absorbed and accumulates in several tissues, leading to increased oxidative damage, mitochondrial dysfunction, and cell death.
This article gives an in-depth overview on the sources of mercury and the adverse effects on the body. There is a long list of (paper) references.
