These two elements are potentially hazardous trace elements and so their emissions from coal combustion must be reduced to protect public health. However, information about Hg and Cl is usually lacking to both policy makers and coal users in many countries using coal for energy. The objective of this study was to understand the concentration, modes of occurrence, and the origin of Hg and Cl in the Balingian coal. Mercury content in the Balingian coal ranges from <1 to 22ppb with an arithmetic mean of 8ppb, while Cl content varies from 100 to 209ppm with an arithmetic mean of 139ppm. The Balingian coal is highly depleted in Hg but it is enriched in Cl, with respect to the Clarke values of these elements. Mercury is mostly organically bounded in the studied section at sampling sites B01 and B03; however, it is mostly inorganically bounded in the studied section at sampling site B02. While Hg in the studied section at sampling sites B01 and B02 has been epigenetically emplaced from overlying rocks by descending groundwater carrying Hg in solution, it has been emplaced syn-genetically in the studied section at sampling site B03. Chlorine is mostly inorganically bounded in the studied section at sampling sites B01 and B02; however, it is mostly organically bounded in the studied section at sampling site B03. Chlorine is mostly syngenetic in origin in all the three studied sections; however, Cl at the lower part of the studied section at sampling site B01 has been emplaced by epigenetic source.
