Deficiencies in emergency mechanisms to handle environmental incidents at some local governments worsen the pollution problem, Wang added.
Industrial contamination is blamed for China's environmental pollution due to the country's rapid economic growth, said E Xueli, a researcher with the China Disease Prevention and Control Center.
Many large-scale factories have been built along rivers at a small cost and with comparatively little fines for their pollutant discharge or even leakages, he said.
Continuous incidents should sound an alarm to local governments and enterprises, E said, adding that to effectively control public pollution incidents, the government must increase penalties to each violator and close down "repeated offenders."
