(NBC News) Levels of cyanide in the waters close to the deadly Tianjin explosion site are as high as 356 times acceptable limits, Chinese authorities said Thursday – but they declared the city’s drinking water was safe.
An update from the Tianjin Environmental Protection Bureau said that tests conducted Wednesday showed that cyanide levels in the river, sea and waste water in the evacuated area around the disaster zone had risen sharply since the blasts.
One testing site at the mouth of a rain water pipe recorded cyanide levels 356 times above acceptable standards, the bureau said.
