mining (ASGM) is the largestsource of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically iso- lated by hand and then heated—often with atorch or over astove—todistill the mercury and isolate the gold. Mercury release from tailings and vaporized mercury exceed

There are seven stable isotopes of mercury with Hg-202 being the most abundant (29.86%). The longest-lived radioisotopes are 194 Hg with a half-life of 444 years, and 203 Hg with a half-life of 46.612 days. Most of the remaining radioisotopes have half-lives that are less than a day. 199 Hg and 201 Hg are the most often studied NMR-active nuclei, having spins of 1/2 and 3/2 respectively.
