Panel Discussion on Tackling the PM2.5 Crisis: Proposing Solutions and Addressing Toxic Air Pollution
A panel discussion was held to brainstorm strategies for turning the PM2.5 crisis into an opportunity for solutions, proposing measures to combat toxic air pollution. The discussion also revealed research findings indicating the presence of heavy metals—known carcinogens—in PM2.5 pollutants in Bangkok and its metropolitan areas. Experts urged the government to address the issue holistically to ensure sustainable development.
On January 29, 2025, Chulalongkorn University hosted the 30th edition of the “Chula the Impact” academic seminar under the theme “Chula Thinks Together: Turning the PM2.5 Crisis Around.” The event gathered experts from various fields to exchange knowledge and present research that could serve as a foundation for driving action, shaping public discourse, and supporting policies and measures to prevent and mitigate air pollution. The goal is to reduce the adverse impacts of PM2.5, a significant environmental issue affecting public health.
Fine particulate matter (PM2.5), with a diameter of less than 2.5 microns, has become an environmental and public health crisis, severely impacting people’s well-being. Major contributors to air pollution include open burning, heavy traffic congestion, industrial activities, and transboundary haze pollution.
“There has been debate in society over whether PM2.5 truly affects health. I can confirm that it does,” stated a researcher. “Numerous global studies consistently show that PM2.5 has both acute and chronic health effects. Acute effects include eye irritation, dry cough, sore throat, difficulty breathing, and skin rashes. Chronic exposure can lead to exacerbated asthma, bronchitis, lung cancer, heart disease, and even Alzheimer’s. Moreover, frequent inflammation caused by PM2.5 can alter cell repair mechanisms, increasing the risk of cancer.”
Assoc. Prof. Dr. Suthirat Kittipongvises from Chulalongkorn University’s Environmental Research Institute emphasized the collective responsibility in managing air quality:
“We must prepare, adapt, and protect ourselves and our families. Raising public awareness about risks and improving data literacy among all groups, especially vulnerable populations, is essential. Effective communication of predictive data can help people prepare for air pollution in advance. The government should address the PM2.5 crisis in all dimensions—not just environmental but also social and economic—to ensure sustainable development.”
