Air pollution is a global issue with serious health impacts to the health and disease status of the public. WHO reported that air pollution is strongly linked to mortality and morbidity from effects on the respiratory and cardiovascular systems, as well as cancer. Thailand and other countries in the region are affected by problems associated with air pollution. Genotoxic air pollutants, in particular, have significant potential impacts on human health. Polycyclic aromatic hydrocarbons have been associated with lung cancer, while volatile organic compounds, such as benzene and 1,3-butadiene, have been associated with leukemia incidence. These pollutants have many sources, including combustion, as well as production and use in the industrial sector. CRI thus focuses on research on the effects of exposure to air pollution on the health of the public, using principles of molecular epidemiology and utilizing various biomarkers, including biomarkers of exposure and biomarkers of early biological effects, such as effects on DNA. The Laboratory of Environmental Toxicology has conducted molecular epidemiological studies on the impacts on health in exposed populations, i.e., those living in Bangkok, using biomarkers of exposure and early biological effects to assess health risks in these populations. Results showed that susceptible populations who are exposed to these genotoxic air pollutants from traffic-related sources (e.g., traffic policemen, street vendors and school children in Bangkok), from their...

I also experienced in development of novel non-viral/antibody based technology for drug and gene delivery into the brain. At Chulabhorn Research Institute, my main research aim is to investigate neuroprotective effects of Thai medicinal plants on acute and chronic brain disorders. Long-term damage of brain cells would possibly lead to the development of neurodegenerative diseases such as stroke, Alzheimer’s and Parkinson’s diseases. An expected outcome to pursue this aim is for the further development of alternative therapy of active compounds deriving from readily available Thai plants.
