Iodine (碘）– rich salt was the hottest item on Chinese shelves Thursday, being snapped up (抢购) by shoppers after rumors spread that iodine intake could help protect one’s body from radiation damage, although the authorities have confirmed that the nuclear crisis in Japan had not affected China.

Rumors also spread about radioactive substances being leaked into ocean water that could pollute Chinese coasts.

The crazy buying has occurred nationwide, from the supposedly easily – harmed eastern coastal provinces to regions far – inland such as Xinjiang.

Supermarkets and convenience stores began reporting the lack of salt stocks from early Wednesday, with all salt sold out at many Carrefour and Wal – Mart stores. Some online clothes stores have begun offering salt as a bonus to customers.

Relevant government departments were trying hard to stop this round of panic – buying.

The Ministry of Health denied the rumor that eating more iodine – rich salt could repair damage from radiation, saying that it is technically impossible to absorb enough iodine for radiation prevention from eating salt.

The government urges the local market authorities to keep all salt sellers in check and to prevent storing and overpricing.

Also the spokesman of the government said that China’s seawater, as a source of salt, would not be affected by the nuclear crisis, as it would be impossible for radioactive substances to reach Chinese waters via the eastward ocean current.

“Reasons behind the salt rush include unclear information on the development of the nuclear crisis and terrifying media reports of the severity of a possible complete meltdown. If the fear of a Chernobyl – like catastrophe cannot be ended, the crazy buying will likely continue,” said a professor from Beijing University.

Beijing urged Tokyo Thursday to better release information at the Fukushima plant.
