Abstract
  • Our recent findings show that mercury emissions from natural sources and re-emission from aquatic and terrestrial surfaces are significantly higher than the mercury emissions from anthropogenic 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. Therefore, our current estimate of global mercury emissions suggests that within the overall contribution (7527 Mg ), as much as two thirds of the total emissions originate from natural sources and re-emission fields. This may have clear repercussions on the necessity of investing a lot of money and reduce emissions from coal combustion and from other anthropogenic sources as we do not have any idea to handle mercury emission from natural sources, which are two times higher than that generated by various human activities.
