Mercury (Hg) is a global pollutant that affects human and ecosystem health. We synthesize understanding of sources, atmosphere-land-ocean Hg dynamics health effects, consider the implications Hg-control policies. Primary anthropogenic emissions greatly exceed natural geogenic resulting in increases reservoirs subsequent secondary facilitate its distribution. The ultimate fate emitted primarily recalcitrant soil pools deep ocean waters sediments. Transfers to largely unavailable occur over...
Abstract. This paper provides an up-to-date assessment of global mercury emissions from anthropogenic and natural sources. On annual basis, sources account for 5207 Mg released to the atmosphere, including contribution re-emission processes, which are previously deposited originating sources, primary reservoirs. Anthropogenic include a large number industrial point estimated 2320 emitted annually. The major contributions fossil-fuel fired power plants (810 yr−1), artisanal small scale gold...
Abstract. Comprehensive field measurements are needed to understand the mercury emissions from Chinese power plants and improve accuracy of emission inventories. Characterization their behavior were measured in six typical coal-fired China. During tests, flue gas was sampled simultaneously at inlet outlet Selective Catalytic Reduction (SCR), electrostatic precipitators (ESP), desulfurization (FGD) using Ontario Hydro Method (OHM). The pulverized coal, bottom ash, fly ash gypsum also field....
Long-term monitoring of data ambient mercury (Hg) on a global scale to assess its emission, transport, atmospheric chemistry, and deposition processes is vital understanding the impact Hg pollution environment. The Global Mercury Observation System (GMOS) project was funded by European Commission (http://www.gmos.eu) started in November 2010 with overall goal develop coordinated observing system monitor scale, including large network ground-based stations, ad hoc periodic oceanographic...
Abstract. An assessment of current and future emissions, air concentrations, atmospheric deposition mercury worldwide is presented on the basis results obtained during performance EU GMOS (Global Mercury Observation System) project. Emission estimates for were prepared with main goal applying them in models to assess (2013) (2035) concentrations this contaminant. The combustion fossil fuels (mainly coal) energy heat production power plants industrial residential boilers, as well artisanal...
We present high‐resolution vertical profiles of methylated mercury (MeHgT = monomethylmercury + dimethylmercury) concentrations in the water column open and marginal areas Mediterranean Sea. MeHgT ranged from <0.015 pmol L −1 to 0.430 (n 130), with maximal occurring within maxima oxygen consumption. Within most biologically active zone (0‐600 m), exhibited a nutrient‐like pattern. The vs. phosphate relationships were highly significant (p < 0.001), whichever station. argue that...
The average global annual mercury emission estimate from biomass burning (BMB) for 1997−2006 is 675 ± 240 Mg/year. This equivalent to 8% of all currently known anthropogenic and natural emissions. By season, the largest emissions occur in August September, lowest during northern winters. interannual variability large region-specific, responds drought conditions. During this particular time period, are tropical boreal Asia, followed by Africa South America. They do not coincide with carbon...

Abstract. The atmospheric deposition of mercury (Hg) occurs via several mechanisms, including dry and wet scavenging by precipitation events. In an effort to understand the cycling seasonal depositional characteristics Hg, samples were collected for approximately 5 years at 17 selected GMOS monitoring sites located in Northern Southern hemispheres framework Global Mercury Observation System (GMOS) project. Total (THg) exhibited annual patterns Hg samples. Interannual differences total are...
The Minamata Convention was established to protect humans and the natural environment from adverse effects of mercury emissions. A cogent assessment emissions is required help implement Convention. Here, we use an environmentally extended multi-regional input–output model calculate atmospheric footprints nations based on upstream production (meaning direct activities a nation), downstream both indirect caused by consumption final goods services in nation). Results show that function...
Abstract. Current understanding of mercury (Hg) behavior in the atmosphere contains significant gaps. Some key characteristics Hg processes, including anthropogenic and geogenic emissions, atmospheric chemistry, air–surface exchange, are still poorly known. This study provides a complex analysis processes governing fate involving both measured data from ground-based sites simulation results chemical transport models. A variety long-term measurements gaseous elemental (GEM) reactive (RM)...
Abstract. Mercury (Hg) is a worldwide contaminant that can cause adverse health effects to wildlife and humans. While atmospheric modeling traces the link from emissions deposition of Hg onto environmental surfaces, large uncertainties arise our incomplete understanding processes (oxidation pathways, deposition, re-emission). Atmospheric reactivity exacerbated in high latitudes there still much be learned polar regions terms processes. This paper provides synthesis monitoring data available...
