air monitoring station
The Ministry of Natural Resources and Environment (MONRE) is moving ahead with a project on building 19 automatic air environment monitoring stations in 17 cities and provinces and 20 stations specializing in measuring PM2.5 dust.
The social distancing policy has minimized emission activities, improving the air quality in Hanoi. However, the activities in the neighborhoods and surrounding provinces still show certain effects on air quality.
Air monitoring stations that warn people about air pollution can be useful, but this is not a radical solution to have a safe living environment.
