Synthesizing published data, we provide a quantitative summary of the global
biogeochemical cycle of vanadium (V), including both human-derived and natural fluxes …

In spite of considerable progresses in recent years, a quantitative and predictive
understanding of atmospheric aerosol sources, chemical composition, transformation …

Abstract The Mesozoic Era featured emplacement of a number of Large Igneous Provinces
(LIPs), formed by the outpouring of millions of cubic kilometres of basaltic magma. The …

Abstract Elemental sulfur (S (0)) is an important intermediate of the sulfur cycle and is
generated by chemical and biological sulfide oxidation. Raman spectromicroscopy can be …

Mercury is a highly volatile, bioaccumulating toxic trace metal with a long (∼ 1yr)
atmospheric residence time. Hg is strongly enriched in volcanic emanations, and volcanoes …

The stocks and flows of the global silver, aluminum, chromium, copper, iron, nickel, lead,
and zinc cycles quantify over 98% of the total mass of metal mobilized by human activity at …

Despite its relatively minor abundance in magmas (compared with H2O and CO2), sulfur
degassing from volcanoes is of tremendous significance. It can exert substantial influence …

Millions of people are potentially exposed to volcanic gases worldwide, and exposures may
differ from those in anthropogenic air pollution. A systematic literature review found few …

Volcanoes are very strong sources of sulphur, acids and other gases, as well as particles,
that are of atmospheric relevance. Some gases only behave as passive tracers, others affect …

Volcanic ash fallout represents a serious threat to people living near active volcanoes
because it can produce several undesirable effects such as collapse of roofs by ash loading …
