SOCAAR establishes collaboration with the Aerosol Science Research Centre in Taiwan


SOCAAR held an online symposium with the Aerosol Science Research Centre (ASRC) at the National Sun Yat-Sen University in Taiwan on November 2 and 16. Sixteen presenters from SOCAAR and ASRC shared their research with 50 participants, including faculty, students and companies participated through two sessions that concluded with the signing of a Memorandum of Understanding (MoU)between the two universities. This MoU will open the door to future collaborative research across many areas of shared interest including the impact atmospheric aerosol on climate change, indoor air quality, sources of pollutants and emission control, toxicity of anthropogenic aerosol, health risk assessment, as well as aerosol education outreach and strategies.
The Aerosol Science Research Center is the only PM2.5 Research Center in Asia. Since its establishment in 2016, it has been actively engaged in various research activities, including exploring the impact of aerosol on ocean ecology and climate change, emission reduction strategies for various sources of PM2.5, and the impact of PM2.5 on human health.
