Seven hundred metric tons of sodium cyanide found on the site of deadly blasts in Tianjin has been confirmed to have been produced by a company in neighboring Hebei province.[Special coverage]
"We are striving to deal with the substance," said Zhi Qunshen, CEO of Chengxin Co.
If there is any leakage of sodium cyanide at the blast site, hydrogen peroxide will be used so that the toxins could be quickly broken down into less toxic chemicals, said Shi Luze, chief of staff of the People's Liberation Army's Beijing Military Area Command.
Stored in cans weighing 50 kilograms each, the chemicals were all supposed to be exported to "customers from more than 10 countries, mainly local mining industries", Wang Jianfang, director of the office of Chengxin Co, told Beijing News, adding that the company has all the documents required for export.
Though a fatal chemical if inhaled, sodium cyanide is commonly used in the mining industry to extract gold from ore - a gold leaching agent that "could largely lower the cost of the extraction process", Chen Jinghe, CEO of Zijin Mining, told China Business News, while admitting that there is a great risk of environmental damage if transportation of the chemical is not strictly regulated.
