Environmental Quality, Atmospheric Science and Climate Change Research Group

1. Introduction

Environmental Quality, Atmospheric Science and Climate Change Research Group (EAAC) was formed in 2014 by Ton Duc Thang University. The focus of this group is to contribute to solving the problems of environmental pollution and Climate change in Vietnam by applying the research results in a practical way.

2. Mission and vision

Our mission is to research on environmental quality of air, water and climate change effects. We also expect to cooperate actively in the same fields with other scientists to enhance research skill and publications.

3. Research topics

a) Epidemiological Research on Public Health - Association and effect of air pollution on community health in Ho Chi Minh City. Quantitate the association of air pollution (ozone, particles, nitrogen oxides, sulphur dioxide, air toxics) on hospitalization and mortality rates due to respiratory diseases, cardiovascular diseases, and stroke.

b) Statistical analysis such as time series analysis, trend analysis, Bayesian statistics on the observed air pollutant concentrations to determine the trend, the association of air pollutants with other variables such as health endpoints and meteorological variables (temperature, wind, humidity, solar radiation...). These analyses will help the development of the best appropriate measures and policy options to reduce air pollution.

c) Research and establish an appropriate meteorological model such as the Weather Research Forecasting (WRF) model to predict 7 to 10 days in advance over a regional area the meteorological variables (temperature, rainfall, humidity, wind speed, wind direction, pressure, and boundary layer height). This model allows real time forecasting over Ho Chi Minh City and the surrounding area. The model will be integrated with an air pollution chemical transport model such as TAPM, CMAQ or CAMx to predict ozone, particles (PM10, PM2.5), nitrogen oxides (NO2, NO).

d) Research on the trans-boundary transport of particles pollution during the dry season in South East Asia (Myanmar, Thailand, Cambodia, Laos and Vietnam). During the dry season, biomass burnings and forest fires in Thailand, Myanmar, Cambodia, Laos and Vietnam have caused high concentrated plumes of particles to be transported across a wide region crossing the country borders.

e) Set up an emission inventory for Ho Chi Minh City and the surrounding areas. The emission data will be part of the Emission Data Management System which can be extracted to be inputted to various air quality model.

f) Research and establish appropriate air pollution dispersion models for regulatory and development purposes using the emission inventory and meteorological data from a meteorological model (such as WRF). The Air Pollution Model (TAPM) from CSIRO Australia (Commonwealth Scientific and Industrial Research Organisation) will be tested and applied to ascertain the feasibility of its application in Ho Chi Minh City.

g) Research to determine the main climate drivers such as the El Nino Southern Oscillation (ENSO), the Interdecadal Pacific Oscillation (IPO) or the Indian Ocean Dipole (IOD) that affect the rainfall in Southern Vietnam.

h) Study the effect of climate change on rainfall, temperature, and the sea level in the future and the mitigation of climate change effects in southern Vietnam, especially in the Mekong Delta.

i) Find an integrated solution to environmental problems in Ho Chi Minh City and surrounding areas.

j) Research on tributyltin compound concentration in Sai Gon river habours and effect to benthic fauna, nematode communities.

k) Environmental impact assessment of dam construction and population, land use to ecological health of Mekong estuarine system.
