2014-02-26 15:06 CNTV Web Editor: Li Yan

In Hebei province, environmental authorities have dispatched unmanned-drones to look for the sources of air pollution, and monitor the daily emission of factories. The drones flew to industrial zones in the cities of Tangshan and Xingtai.

The high-definition cameras carried by the drones took pictures of every chimney discharging waste gas into the air. Pictures showed that some companies' emission levels did not meet the national standards.

Inspection groups visited those companies and demanded emission reports from them. Those who failed to meet the standard have been asked to halt their production.
