We study the chemical composition and the dynamic evolution of air pollutants such as particulate matter (PM), ozone (O3) and volatile organic compounds (VOCs). Specifically, we measure the chemical composition of complex mixtures in PM and VOCs, which is vital for us to understand their emission sources or the chemical process leading to their formation; we also simulate the chemical reactions (e.g., aqueous-phase photolysis or gas-phase oxidation) occurring in the atmosphere, and find out the key precursors and conditions that lead to the deteriorating secondary pollution formation.
We are particularly interested in the urban air pollution that is affected by anthropogenic emissions. At the same time, we are also interested in how the anthropogenic air pollutants evolve under the influence of air masses of marine origin (with high relative humidity and high halogen content) and emissions from forested areas (e.g., biogenic VOCs).
Air pollution is one of the most serious environmental issues we are facing. Pollutants such as particulate matter (PM), ozone (O3), volatile organic compounds (VOCs), nitrogen oxides (e.g., NO and NO2), sulfur dioxides (SO2), carbon monoxide (CO), carbon dioxide (CO2), etc., have profound impacts on the environment. They can either induce adverse health effects to the ecological systems (human included) or alter radiative balance of the atmosphere (leading to climate change). Understanding the sources and processes of these air pollutants is crucial in the formulation of control policies to tackle the problem. Due to the complexity in the chemical composition (for example, for PM and VOCs), as well as rapid changing of their chemical identities because of reactions, investigations of air pollution require corroborative evidence from field observation, laboratory experiment, to model simulation so as to reach scientifically sound conclusions, providing a solid ground for control measures to be formulated.
We use sophisticated techniques such as mass spectrometry at fixed stations or miniature sensors onboard mobile platforms (e.g., unmanned aerial vehicle, UAV) to measure detailed chemical components (e.g., PM, black carbon, and VOCs) and spatial distributions of those air pollutants. We also employ laboratory simulators such as single-particle trap (electrodynamic balance, EDB), bulk photolysis reactor, flow cell reactor, or oxidative flow reactor (OFR) to interrogate the chemical changes, as well as changes in physicochemical properties, of aerosol particles.
