Abstract

Vietnam Air Quality Report 2016 published recently by the Vietnam Union of Sustainable Energy shows that the overall picture of air in Hanoi is in an alarming state, air quality index (AQI ) and PM dust concentration of 2.5 (dust with học2.5 mm kinetic diameter) exceeds the national and world standards. One of the causes of air quality degradation is due to the condition of old and worn motorcycles discharging air into the environment. Currently in big cities like Hanoi and Ho Chi Minh City, motorcycles account for 95% of the vehicles and consume 56% of gasoline, the hydrocarbon emissions account for 94%, carbon monoxide (CO) accounts for 87%. And nitrous oxide accounts for 57%. This shows that the air pollution caused by motor vehicles is increasing at an alarming rate. Currently in Vietnam, there are about 40 million motorbikes, of which there are vehicles operating from the 80s to 90s of the previous century but still circulating. Not only traffic insecurity, but in the process of operation, these "overly" vehicles also seriously affect the environment and people's health. These vehicles are used by outdated technology, so the ability to burn fuel is not exhausted, discharging into the environment many times more cars and most of toxic emissions are hydrocarbons, greatly affecting human health.
