TL;DR: In this paper, an empirical gas-particle partitioning relationship log 10(K 1 ) = (10±1)- (2500±300)/T where K = (PBM/PM2.5)/RGM with PBM and RGM in common mixing ratio units, PM 2.5 in µg m 3, and T in K.

TL;DR: This work shows that locally deposited mercury close to coal-fired utilities has declined more rapidly than previously anticipated because of shifts in speciation from air pollution control technology targeted at SO2 and NOx.

TL;DR: A global inventory of commercial Hg uses and releases to the atmosphere, water, soil, and landfills from 1850 to 2010 is presented to force a global biogeochemical model that includes new estimates of the global burial in ocean margin sediments.

TL;DR: An improved treatment of the surface ocean in the GEOS-Chem global 3-D biogeochemical model for mercury (Hg) is developed, replacing the globally uniform subsurface ocean Hg concentrations used in the original model with basin-specific values based on measurements.

TL;DR: It is found that including this sink in a fully coupled global biogeochemical box model helps to balance the large anthropogenic release of Hg from commercial products recently added to global inventories and implies that legacy anthropogenic Hg can be removed from active environmental cycling on a faster time scale.
