Global biotransport of mercury through rice and other crops. a Global biotransport of THg and MeHg through production, trade, supply, and consumption of rice grain and through different management options of rice residues; b global THg generated in crop residues in 2016. In a, fluxes of atmospheric THg emission and deposition refer to the study of Outridge et al.31; the flux of root absorption of THg from soil was calculated based on the rice THg uptake flux synthesized by Kwon et al.67; and the absorption of atmospheric Hg by rice leaves was estimated by the flux of Hg over foliage estimated by Wang et al.68. The global harvested area of rice was obtained from the FAO23
