Mercury is a non-transition metal and is an extremely rare element in the earths crust, having an average mass abundance of only 0.08 ppm (Sinicropi et al., 2010). Organic mercury compounds are formed when mercury combines with carbon. Mercury contamination is a serious issue that impacts both ecosystem and human health on a global scale.
