190353 Evaluating PM 10 in Rural Areas and in Hanoi and Ho Chi Minh City in VietnamMonday, October 27, 2008
Since joining the World Trade Organization in 2007, the Vietnamese government has been charged with developing improved environmental policies. The objective of this study was to measure air pollutant exposures to particulate matter (PM 10) in rural areas and in Hanoi and HCMC.
Fifty-one samples of PM 10 were measured using a DustTrak (model 8520, TSI, Minnesota) for 1 hour sampling times during rainy season in Vietnam. The average of the temperature and relative humidity was 33°C (range 26.5-39.3°C) and 75% (rage 49-100%), respectively. Dust particulate concentration ranges from 11 to 313µg/m3 were observed during various times of the day. PM 10 and both relative humidity and temperature were not correlated (R2=0.006, 0.062). A comparison of the concentration ratios for PM 10 between rural area and downtown of Hanoi and HCMC yielded slight differences. Also, the PM 10 concentration in outdoor atmospheres was slightly higher than indoors. The PM 10 concentrations tended to be higher in HCMC than in Hanoi (p=0.024). It is shown that the air quality of outdoor ambient in Hanoi has deteriorated in recent years. Probable causes for this deterioration include the use of 20 million unprecedented diesel motorcycles and increasing number of industries in and around Hanoi. Air pollution in Vietnam is a serious current concern because it is linked with adverse health effects including respiratory, neuralgia, pulmonary, and cardiovascular diseases. Suggestions for regulations that can be incorporated quickly into an integration of air quality and transport management including use of a biodiesel motorcycle are presented.
