The researches on effective abatement strategies propose solutions to reduce air pollution. It
consists mainly of master thesis which is carried out at IER (Institute for Environment and
Resources in HCMC). These researches are focused only on some typical aspects of
abatement strategies at small scale, due to the lack of the information for research,
methodology, etc. Nguyen (2000) proposed some methods to reduce air pollution by traffic
in HCMC as well as for developing public transportation system and using unleaded
gasoline. Another study proposed technical solutions for reducing air pollution level by
traffic activities (Duong, 2004).
In conclusion, both the developed and developing cities have air pollution problem,
especially in the developing countries where it is related to high level of air pollution. It’s
urgent to adapt an air quality management (AQM) system for improving the air quality in
these cities. In the next section, the research for improving air quality in HCMC is carried
out by using numerical tools.
