It is obvious that Vietnamese authorities already
realizes that air pollution is an issue in Vietnam, especially in the urban
areas (Thomas Fuller, 2007). Looking at current statuses in big cities in
Vietnam, we can see that most worrisome is that people in the working age group
are the ones most often affected by air pollution (Vietnamnet, 2017). Because
they have to go to the office to work every day; therefore, they can not avoid
facing these dust. And the most serious impact of urban air pollution is damage
to human health. According to the global environmment outlook (GEO-4) released
by the United Nations Environment Program, Hanoi and HoChiMinh city are among
the six cities suffering the most from severe air pollution in the world.
Especially, the children and old people are very sensitive with outdoor
environment; therefore, they also have difficulty in coping with air pollution.
An increasing number of people are now suffering from some serious deseases
such as cancer, cardiovascular and
respiratory diseases. According to incomplete statistics, in recent year, the
number of patients relating to air pollution is increasing. The number of
children hospitalised for asthma treatment, respiratory bacteria, and cough in
some hospitals in Hanoi and HoChiMinh cities has increased many times.
According to medicinal specialists’ forecast, the number of cancer cases
including lung cancer in Vietnam will increase significantly in the next 5
In addition, air pollution cause a huge economic
impact for not only government but also people who are affected by this
problem. Statistic from the Ministry of Transport revealed that 2.5 million
patients spend an estimated $66.8 million a year for examinations and treatment
for respiratory diseases each year in Ha Noi alone, and incomes are redeuced
20% and health of citizens also by 20%. They also show that in HoChiMinh City,
5.6 million patients spend $70.9 million a year for similar treatment. There are alarming numbers by its dizzying
increase over the years. As a result, experts say that Vietnam’s current GDP
growth is estimated to 8%, but if the environmental losses caused by the
development process are taken into account, the real growth rate would be 3-4%
(UNEP, 2007). It means Vietnam’s economy will be declined to extremely low
level and it also threatens economic growth in medium and long term because the
number of days having average hourly daily value higher than the allowed level
is increasing through years, mostly highest in peak hour when the density of
cars and motorbikes is high in the streets.
Furthermore, air pollution even increases greenhouse
gases that cause climate change, acid rain, and degrade ecosystem.
