QCVN 05:2013/BTNMT
National Technical Regulation on Ambient Air Quality

Foreword
QCVN 05:2013/BTNMT was complied by Drafting Committee of national technical regulations on
air quality; submited by Vietnam Enviroment Administration, Department of Science &
Technology, Department of Legal Affairs and promulgated in line with Circular No. 32/2013/TTBTNMT dated October 25, 2013 issued by Minister of Natural Resources and Environment


1. General Provision
1.1. Scope of Regulation
1.1.1. This Regulation deals with limitations on values of basic factors including sulfur

dioxide (SO2), carbon monoxide (CO), dioxide nitrogen (NO2), ozone (O3), total
suspended particles (TSP), PM10, PM2,5 particles, and lead (Pb) in ambient air.
1.1.2. This Regulation applies to supervision and assessment of ambient air quality.
1.1.3. T his Regulation does not apply to air within manufacturing facilities and indoor air.
1.2. Interpretation of terms

In this Regulation, the terms below are construed as follows:
1.2.1. Total suspended particles (TSP) is total particles with aerodynamic diameter less than or
equal to 100µm.
1.2.2. Particle PM10 is total suspended particles with aerodynamic diameter less than or
equal to 10 µm
1.2.3. Particle PM2,5 is total suspended particles with aerodynamic diameter less than or equal
to 2,5 µm.
1.2.4. Average 1 hour : The arithmetic average of the measured values over a period of 1 hours
1.2.5. Average 8 hours : The arithmetic average of the measured values over a period of 8
consecutive hours
1.2.6. Average 24 hours : the arithmetic average of the measured values over a period of 24
hours ( a day )
1.2.7. Annual average : the arithmetic average of the 24- hour average values measured over a
period of one year
2. Technical Reputation
Maximum value of basic parameters of ambient air is specified in Table 1
