Spatial-temporal changes of land-use mercury emissions in China

Land use change is closely related to human activities, and has significant impacts on pollutant emissions. Mercury (Hg) the most toxic heavy metal element gas damaging environment severely, China largest mercury Yet, there inadequate research which measured emissions caused by land in China. To assess systematically, we establish spatial-temporal series of land-use emission inventories considering indicators both natural anthropogenic analyzing effects type conversion intensities. The results show that had a growth rate 1.35% from 2000 2015. Regions with large increase were those built-up expansion. embodied calculated multi-regional input-output model an average increasing 16.53% 2007 Further, mining industry residential accounted for about 73.1% Jiangsu Shandong emissions, while Xinjiang Gansu but rather small land. can inform pollution mitigation policies through management.
