Most studies on the atmospheric behaviour of mercury in North America have excluded a detailed treatment of natural mercury emissions. The objective of this work is to report a detailed simulation of the atmospheric mercury in a domain that covers a significant part of North America and includes not only anthropogenic mercury emissions but also those from natural sources including vegetation, soil...
Most regional models that have been developed to study the behaviour of mercury (Hg) in the environment do not include detailed treatment of natural (i.e. non-anthropogenic) Hg emissions. We have developed a Hg emission model including natural sources; incorporated it into the CMAQ-Hg model (US EPA) and used it to study the behaviour of Hg in the atmosphere.Our natural Hg emission model uses an algorithm...
