Mercury Cycling and Bioaccumulation in a Changing Environment

Mercury (Hg) is a global, toxic pollutant that has important implications for environmental and public health. Recently, the increasing awareness of Hg toxicity has led to the replacement of Hg in many areas and industries; however anthropogenic activities such as coal burning, small and large scale gold mining, and smelting of metal ores continue to release significant amounts of Hg into the environment. In particular, the global atmospheric distribution of Hg can result in the pollution of pristine areas with no known local point sources. The chemical speciation of Hg determines its mobility and toxicity and Hg methylation is a critical component of the mercury cycle. For example, flooded soils and sediments and microbial methylation can occur and serve as an ideal environment for the transformation of inorganic mercury to monomethylmercury (MMHg). MMHg is a potent neurotoxin that can affect human health, including negative effects on the cardiovascular system, and exposure is primarily via the consumption of contaminated fish and rice, whereas elemental Hg vapor is also harmful to the central nervous system and inorganic Hg compounds can affect human kidneys.
Recently the United Nations Environment programme has coordinated the signing of the Minamata Convention on Mercury which has the primary goal of reducing anthropogenic releases of Hg and protecting environmental and human health. This UN convention, and its broad international support, both represent strong evidence of the global importance of the mercury pollution issue. This virtual special issue brings together knowledge on the behavior of Hg in the environment including advances in Hg biochemistry, trophic transfer, human health and future research needs.
