Vietnam's issue of Air Pollution




Air pollution in Vietnam are at unhealthy levels according to one government study. Vietnam is a home to millions of motorbikes that buzz through major cities like Hanoi and Saigon. A study that took place from 2011 to 2015 found that Vietnam's air has become worse. Nitrogen dioxide concentration in Hanoi was measured at up to 1.3 times above the permitted levels. In Ho Chi Minh, the study found twice the permitted level.  Traffic and industrial activities are major sources of air pollution in Vietnam's major cities. In Ho Chi Minh, 750 motorcycles are registered every day. Acicn.org, a team based in China with close ties to U.S diplomatic missions, ranked air in HCMC as "Unhealthy." Hanoi is home to 5.5 million individuals and 1.8 million motorbikes. The air in these two major cities contain dangerous levels of benzene and sulfur dioxide. Researches have also found dangerous microscopic dust known as PM10, which can potential cause lung cancer. The Vietnamese government's way of combating the rise of pollution is by installing a major and efficient public transportation system. At the heart of Vietnam's air pollution is dirty fuel. Companies in Vietnam have resisted purchasing higher quality fuel because it is more expensive. Vietnam is showing signs of awareness for a country with tightly controlled information.
