	<abstract content_type="html">This paper provides an up-to-date assessment of global mercury
      emissions from anthropogenic and natural sources. On an annual basis,
      natural sources account for 5207 Mg of mercury released to the global
      atmosphere, including the contribution from re-emission processes,
      which are emissions of previously deposited mercury originating from
      anthropogenic and natural sources, and primary emissions from natural
      reservoirs. Anthropogenic sources, which include a large number of
      industrial point sources, are estimated to account for 2320 Mg of
      mercury emitted annually. The major contributions are from fossil-fuel
      fired power plants (810 Mg yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;), artisanal small scale gold
      mining (400 Mg yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;), non-ferrous metals manufacturing
      (310 Mg yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;), cement production (236 Mg yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;), waste
      disposal (187 Mg yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;) and caustic soda production
      (163 Mg yr&lt;sup&gt;&amp;minus;1&lt;/sup&gt;). Therefore, our current estimate of global
      mercury emissions suggests that the overall contribution from natural
      sources (primary emissions+re-emissions) and anthropogenic sources
      is nearly 7527 Mg per year, the uncertainty associated with these
      estimates are related to the typology of emission sources and source
      regions.</abstract>
