At the same time, at Thach That station, the air pollution index was also very high, AQI 241 - purple threshold.
According to Mr. Le Hoai Nam - Deputy Director of the Department of Environment, Ministry of Agriculture and Environment, monitoring results show that in Hanoi and some provinces in the Red River Delta, fine dust pollution is a very complicated and high situation.
The main causes are emissions from industrial sectors, emissions from transportation, waste from the agricultural sector, the problem of burning household waste in localities and construction activities...
Experts recommend that when the air quality index reaches the hazardous level (AQI 301 500), people should minimize going out, temporarily stop outdoor activities and switch to indoor activities. Close your doors to avoid contact with pollution. For sensitive groups, the recommendation is even more strict: absolutely do not go out and ensure the indoor environment is airy and safe.
