TL;DR: Mercury emissions reductions will yield rapid (years) reductions in fish methylmercury concentrations and will yield concomitant reductions in risk, however, a full response will be delayed by the gradual export of mercury stored in watersheds.

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: It is shown that THg and MeHg loading can be extremely variable within a heterogeneous boreal landscape and that processes such as Hg photoreduction and emission from foliage should be considered when estimating dry deposition of Hg.

TL;DR: The design of a dynamic chamber system that allows full transmission of PAR and UV radiation and permits enclosed intact foliage to maintain normal physiological function while Hg(0) flux rates are quantified in the field is presented.

TL;DR: It is hypothesized that as Cl- concentrations in snowpacks increase, inorganic Hg(II) occurs principally as less reducible chloro complexes and, hence, remains in an oxidized state, and snowpacks that receive both marine aerosol deposition of Cl- and deposition of Hg (II) via springtime atmospheric Hg depletion events, for example, may contain significant loads of HG(II.
