EDGAR v8.1 Global Mercury Emissions

EDGARv8.1 provides emissions not only for the greenhouse gases and air pollutants per sector and country but also for toxic pollutants such as mercury.

EDGARv8.1_toxHg includes:

Total mercury (Hg)and mercury species
Elemental mercury (Hg0; Hg_G)
Gaseous oxidised mercury (Hg2+; Hg_D)
Particle-bound mercury (Hg-P; Hg_P)
Emissions from large scale biomass burning with Savannah burning, forest fires, and sources and sinks from land-use, land-use change and forestry (LULUCF) are excluded.

For the energy related sectors the activity data are primarily based on IEA data from IEA (2022) World Energy Balances, (www.iea.org), all rights reserved, as modified by Joint Research Centre, European Commission, whereas the activity data for the agricultural sectors originate primarily from FAO (2022) (https://www.fao.org/faostat). United States Geological Survey (USGS), UNFCCC and World Steel Association (worldsteel) recent statistics are also used for activity data. The Artisanal Small Scale Gold Mining (ASGM) sector was updated based on information from country reports and scientific literature. Additional information can be found in Muntean et al. (2024, in preparation).

Compared to the previous EDGAR version, v4.tox2, the following major updates have been included:

Update of activity data up to 2022
Updates of technology penetration and abatement measures for power plant
New spatial proxies as described in Crippa et al. (2024)

EDGARv8.1数据集不仅提供各部门、各国的温室气体与大气污染物排放数据，还涵盖汞等有毒污染物的排放情况。

EDGARv8.1_toxHg数据集涵盖以下汞排放相关数据：总汞（Hg）及汞形态物种、元素汞（Hg⁰；Hg_G）、气态氧化汞（Hg²+；Hg_D）以及颗粒结合态汞（Hg-P；Hg_P）；但本数据集排除大规模生物质燃烧（含稀树草原燃烧、森林火灾）的排放，以及土地利用、土地利用变化与林业（Land Use, Land Use Change and Forestry, LULUCF）的源与汇数据。

能源相关部门的活动数据主要源自经欧盟委员会联合研究中心修改的国际能源署（International Energy Agency, IEA）2022年发布的《世界能源平衡表》（www.iea.org，保留所有权利）；农业部门的活动数据则主要来自联合国粮食及农业组织（Food and Agriculture Organization of the United Nations, FAO）2022年发布的公开数据（https://www.fao.org/faostat）。此外，本数据集还采用了美国地质调查局（United States Geological Survey, USGS）、联合国气候变化框架公约（United Nations Framework Convention on Climate Change, UNFCCC）以及世界钢铁协会（World Steel Association, worldsteel）的最新统计数据作为活动数据来源。手工小型金矿开采（Artisanal Small Scale Gold Mining, ASGM）部门的活动数据则基于各国报告与科学文献进行了更新。更多详细信息可参见Muntean等人（2024，待刊）的研究成果。

相较于此前的EDGAR版本v4.tox2，本数据集包含以下三项主要更新：
1. 活动数据更新至2022年；
2. 发电厂技术渗透率与减排措施的更新；
3. 新增空间代理变量，详见Crippa等人（2024）的相关研究。

背景与挑战

背景概述

EDGAR v8.1 Global Mercury Emissions数据集提供了全球范围内总汞及其不同形态（如元素汞、气态氧化汞和颗粒结合汞）的排放数据，覆盖多个行业和国家。数据集更新至2022年，并改进了电厂技术数据和空间代理，排除了大规模生物质燃烧和土地利用变化的影响。
