Global Emissions EDGARv4.tox1 (February 2014)

The EDGAR Team compiled the global mercury emission inventory, which is included in EDGARv4.tox1; three different forms of mercury have been distinguished: gaseous elemental mercury, gaseous oxidized mercury and particle bound mercury. The paper “Trend analysis from 1970 to 2008 and model evaluation of EDGARv4 global gridded anthropogenic mercury emissions” published open access in Science of the Total Environment (http://www.sciencedirect.com/science/article/pii/S0048969714008572), describes this emission inventory and the results of its evaluation with GEOS-Chem global 3-D mercury model.

EDGARv4.tox1 mercury emissions are disaggregated by sector and gridded emission data files are provided in two formats: netCDF (in kg/m2/s) and .txt (in t/cell). The EDGARv4.tox1 contains 0.1degx0.1deg emission gridmaps of total mercury and mercury species from 1970-2008. The emissions of total mercury (Hg), gaseous elemental mercury (Hg_G), gaseous oxidized mercury (Hg_D) and particle bound mercury (Hg_P) by sector are aggregated as following:

1. cement=cement production,
2. chlor=chlor-alkali industry, mercury cell technology,
3. comb_power_ind=combustion in power generation and in industry,
4. comb_res_oth= combustion in residential and other combustion (transformation industry and oil refineries),
5. gold_A=artisanal and small scale gold production,
6. gold_L=large scale gold production,
7. Iro=iron and steel production,
8. nfe_oth=production of Zn, Cu, Pb and Hg,
9. waste=solid waste incineration and agricultural waste burning.

The EDGARv4.tox1 emissions are calculated based on the energy balance statistics of IEA (2014) (Internet: http://www.oecd-ilibrary.org/energy/co2-emissions-from-fuel-combustion-2014_co2_fuel-2014-en)
