A better understanding of the discrepancies in multi-scale emission inventories could provide indications for their limitations and further improvements. We develop a bottom-up inventory of Hg emissions for Jiangsu, China. Compared to the national and global inventories, the largest total Hg emissions and fraction of Hg2+ are estimated. The crucial parameters responsible for the differences include Hg contents in coals/materials, abatement rates of emission control devices, and activity levels.
