“…Based on these criteria, 101 peer-reviewed articles were selected. Statistical databases relating to provincial paddy yields and population size were taken from the latest China Statistics Yearbook (NBS 2015), and the domestic rough rice trade flow was determined from the 2015 Report of the Chinese Rice Industry (Zheng 2015).…”

“…Cadmium accumulation in rice is dependent on the rice variety (Zhao et al 2009), and the consumption of the rice produced is driven by rice yield (Liu et al 2014;Shi 2015). The domestic rice trade has a close relation with the riceproducing regions (Zheng 2015). For example, three provinces in northeastern China are considered as one large region in terms of rice output (Zheng 2015).…”

“…The domestic rice trade has a close relation with the riceproducing regions (Zheng 2015). For example, three provinces in northeastern China are considered as one large region in terms of rice output (Zheng 2015). So, it is significant to analyze the Cd distribution in the three dominant riceproducing regions of China.…”

“…Other color dots represented Cd pollution sources in this study Determination of risk and the most critically polluted regions of China based on the rough rice trade flow Rice is the staple food for an increasing number of people in China, and the rice yield has increased year by year since 2002 (Shi 2015). In 2014, China's rough rice yield was 206.51 million tons (NBS 2015), and the output and input quantities were 0.63 tons and 3.90 million tons, respectively (Zheng 2015). There are large regional differences in rice production in China (Fig SI-3).…”

“…The rough rice yield in nine regions exceeded 10 million tons in 2014. According to the Report of Chinese Rice Industry in 2015 (Zheng 2015), three provinces in the northeast (Heilongjiang, Jilin, and Liaoning provinces), four provinces in the central-south (Anhui, Hubei, Hunan, and Jiangxi provinces) and Jiangsu province had rough rice surpluses to output, and Zhejiang, Fujian, Guangdong, and Guangxi provinces in the coastal region had large deficits (Fig 5). A rough rice trade flow has formed in China over recent decades (Zheng, 2015).…”

Rice is a staple food by an increasing number of people in China. As more issues have arisen in China due to rice contaminated by cadmium (Cd), Cd contamination in arable soils has become a severe problem. In China, many studies have examined Cd contamination in arable soils on a national scale, but little studies have focused on the distribution of Cd in paddy fields. This study explored the spatial pattern of Cd in paddy soils in China, made a preliminary evaluation of the potential risk, and identified the most critically contaminated regions based on the domestic rough rice trade flow. The results showed that Cd concentrations in paddy soils in China ranged from 0.01 to 5.50 mg/kg, with a median value of 0.23 mg/kg. On average, the highest Cd concentrations were in Hunan (0.73 mg/kg), Guangxi (0.70 mg/kg), and Sichuan (0.46 mg/ kg) provinces. Cd concentrations in paddy soils in central and western regions were higher than those in eastern regions, especially the southeastern coastal regions. Of the administrative regions, Cd standard exceedance rate was 33.2 %, and the heavy pollution rate was 8.6 %. Regarding to Cd of paddy soil, soil environmental quality was better in Northeast China Plain than in Yangtze River Basin and southeastern coastal region. Mining activities were the main anthropogenic pollution source of Cd in Chinese paddy soil. Based on rice trade, more of the Chinese population would be exposed to Cd through intake of rice produced in Hunan province. Certain regions that output rice, especially Hunan province, should be given priority in the management and control of Cd contamination in paddy soil.
