Reduction or possible elimination of Hg from artisanal and small-scale gold mining (ASGM) is one of the main goals of the Minamata Convention on Mercury, which has been signed by many countries involved in ASGM, including Ghana. This article provides a recent overview of ASGM gold production and Hg use in Ghana. In addition, in order to highlight the impacts of Hg use in Ghana, a review was conducted on research studies investigating Hg pollution in waterbodies, soils, fish, and humans caused by ASGM over the past two decades. The continued use of Hg in Ghana's growing ASGM sector has resulted in reportedly high Hg levels found in water, sediments, crops, and miners, which exceed international guidelines. A subsequent ASGM ban and increased monitoring of illegal mining activities in Ghana have not ultimately been successful at significantly reducing Hg use and its associated impacts caused by rampant use in the country. Moreover, Hg alternatives in the ASGM sector are limited in Ghana, with little funding, support, education, and training in place to promote their implementation. As gold produced by ASGM continues to increase annually, clear policy reforms targeting Hg use are vitally needed, as well as efficient strategies to remediate Hg-contaminated areas.
