Key Point

  • The low-cadmium Indica rice trial plantation (soil contains 1.5 mg/kg of cadmium) is located in Xiangtan County, Hunan Province. Two rice samples registered 0.06 mg/kg and 0.07 mg/kg of cadmium, which is below the national standard of 0.2 mg/kg.

ChinaAg Comments

  • Cadmium is a heavy metal that is produced by refining zinc ores. China is world’s largest zinc producer, and was forecasted to account for 37% of the global zinc mine production in 2017. Cadmium is used in various alloys, as well as to produce batteries, televisions, semiconductors, etc. Excessive cadmium consumption can damage the kidneys, lungs, liver, and bones.
  • In August 2017, the World Bank in China announced it would lend USD 100 million to ameliorate heavy metal pollution in Hunan Province, central China. The World Bank program will encompass 8,000 hectares of farmland (primarily rice crops).
  • In February 2013, Guangdong Province reported that cadmium tainted rice from Hunan Province was distributed within Guangdong. In May 2013, there were widespread reports of cadmium rice being served at restaurants in Guangzhou, Guangdong Province.
  • In February 2012, the Hunan provincial government began a cadmium testing initiative.
  • According to a 2011 survey conducted by China’s Ministry of Agriculture, 67.8% of the sampled rice paddy land (or 107,200 hectares out of 182,133 ha) were contaminated with pollutants including cadmium, arsenic, nickel, copper, mercury and chromium. The survey took place in Hunan, Hubei, Jiangxi and Sichuan.
  • In 2009, a research group from the Chinese Academy of Sciences (CAS), South China Agricultural University, Xiamen University and the University of Aberdeen in Scotland tested 100 samples of rice from Hunan Province. Of the 100 rice samples, 65 had excessive cadmium.
  • Established in 1999 and headquartered in Changsha, Hunan Province, Yuan Longping High-Tech Agriculture (SHE:000998) produces and distributes specialized crop seeds. These include hybrid rice seeds, hybrid pepper, hybrid rapeseed, hybrid corn, hybrid cotton, musk melon and vegetables.
