Understanding the causes and timings of mass extinctions are important for our
understanding of the evolution of life on Earth and how major biogeochemical cycles have …

A review of the available information on global Hg cycling shows that the atmosphere and
surface ocean are in rapid equilibrium; the evasion of Hg 0 from the oceans is balanced by …

Mercury (Hg) is increasingly being used as a sedimentary tracer of Large Igneous Province
(LIP) volcanism, and supports hypotheses of a coincidence between the formation of several …

The end-Triassic mass extinction overlapped with the eruption of the Central Atlantic
Magmatic Province (CAMP), and release of CO 2 and other volcanic volatiles has been …

Hg with small positive∆ 199Hg values, which Grasby et al. propose could result from the
absorption of atmospheric Hg2+ by volcanic plume ash or the photoreduction of Hg2+ in the …

Since pre-industrial times, anthropogenic emissions of Hg have at least doubled global
atmospheric Hg deposition rates. In order to minimize environmental and human health …

Volcanic activity associated with the emplacement of Large Igneous Provinces (LIPs) has
been linked to most Phanerozoic extinctions/episodes of major environmental change. In …

This paper summarizes recent advances in the understanding of the exchange of Hg
between the atmosphere and natural terrestrial surfaces including substrates (soil, rocks …

We estimate that a cumulative total of 1540 (1060–2800) Gg (gigagrams, 109 grams or
thousand tonnes) of mercury (Hg) have been released by human activities up to 2010, 73 …

Natural terrestrial sources of atmospheric mercury (Hg) include geologically enriched
substrate, volcanoes, geothermal areas, forest fires, vegetation, and" background soils"(soils …
