| Ho Chi Minh, Vietnam 07/2010 |
My first time traveling to Vietnam was a total culture shock. It never occurred to me that the main mode of transportation were motor bikes - both in the cities and rural areas. Don't get me wrong, it's not as bad as Beijing - however, traffic pollution is a problem everywhere.
Second time - it was still a shock to me. The major cities that I traveled to, including: Ho Chi Minh, Danang, Da Lat, and Nha Trang and the smaller cities of Pleiku and Kon Tum - these are very distinct regions, but the mode of transportation was the one thing that was familiar in all of the cities.
Air pollution is a pervasive health and environmental issue. The air quality reduces when natural or anthropogenic substances accumulate in the atmosphere. Some of these nasty substances include (but not limited to): CO, CO2, fine PM, and your NOx, VOCs and SOx's. This is the chemical makeup that allows us to travel thousands of kilometers. Amazing right?
We can't forget that air quality is also affected by a range of factors, such as weather conditions and topography of a region. Auto emissions are just one of many anthropogenic culprits of air pollution.
