Investigators: Erik Velasco

Description: A robust and transparent air quality management supported by scientific information is fundamental to achieve clean air.

Air quality has become one of the most important environmental and health concerns in the modern life. Links between air pollution and health effects are observable even where pollutant levels are seemingly low. It is known that poor air quality can cause short- and long-term impacts on public health, resulting in increased health costs, loss in manpower hours, and ultimately reduction in quality of life.

Unlike many industrialized metropolitan areas, Singapore is far from being a hazy and highly polluted city. However, similar to many other cities, fine particles, particles smaller than 2.5 µm in size, exceed the international standards and guidelines of the World Health Organization. A science-based and transparent air quality management under a multipollutant framework can assist Singapore's efforts to reduce its levels of airborne particles, and in general of any atmopsheric pollutant.

The atmosphere over tropical cities is not well researched and represents an opportunity for Singapore to expand its agenda in environmental research and development. In this context, our research has the aim of providing a scientific base for devising new regulations to improve the air quality and climate change mitigation of Singapore and other tropical cities. A comprehensive characterization of emission sources, transport, and fate of pollutants and greenhouse gases will build a strong knowledge base applicable to other fast-growing cities in Southeast Asia and tropical places in general.

The following chart presents the topics on air quality managemet and climate change mitigation covered by our team.

Our findings and data are publicly available. Results go over a peer-review process before publication. Grad and undergrad students are always encouraged to particpate in our projects as part of the educational and outreach activities.

We also work closely with journalists, who are the perfect vehicle for communicating our findings with the society. The public's perception of scientists' expertise and trustworthiness are very important.
