Global biotransport of methylmercury through the international rice trade. a shows the major MeHg flows (>0.5 kg yr−1) induced by the international rice trade between the regions. b–e show the top ten partner countries of the major rice MeHg-exporting countries, i.e., India (b), the United States (c), Vietnam (d), and Thailand (e), respectively. Data are in 2013. Error bars in figures represent the interquartile range of the confidence intervals
