Prime Minister Nguyen Xuan Phuc has asked the leaders of Hanoi to apply radical solutions to handle air pollution.
The fact that air pollution alerts in HCMC are not timely made available is attributable to the Center for Environment and Natural Resources Monitoring’s use of outdated environmental monitoring devices, said Cao Tung Son, director of the center.
Many people in Hanoi are buying air purifiers to cope with rising air pollution.
