"Chinese authorities warned that cyanide levels in the waters around the Tianjin Port explosion site had risen to as much as 277 times acceptable levels although they declared that the city's drinking water was safe.

The local government, under pressure from China's leaders in Beijing to improve industrial safety, also said it would relocate chemical plants away from the area, where thousands of residents were forced to evacuate last week after the release of toxic chemicals by explosions that killed 114 people.

China's ruling Politburo Standing Committee called on all levels of governments during a special meeting on Thursday to do more to implement and monitor industrial safety rules, the official Xinhua news agency reported."
