Sodium cyanide fears eased by authorities

Authorities said on Sunday that an estimated several hundred metric tons of sodium cyanide stored at the scene of Wednesday's killer explosions in Tianjin have not harmed human health or the environment.

A number of containers, each holding 25 kilograms of the highly toxic inorganic compound, have been found in two areas at the site - many of them still intact, Shi Luze, chief of staff for the Beijing Military Area Command, said at a news conference.

"For those that were broken after the blasts, we used hydrogen peroxide and other solutions to control pollution from them."
