About A.S.T
Atmospheric Science & Technology lab
The Atmospheric Science & Technology Laboratory conducts extensive research into the sources, transport, and physicochemical transformation of fine particles, organic compounds, and heavy metals, including mercury, within various environmental systems.
Our Vision
We are particularly interested in air pollution and the exchange of pollutants between the surface and the atmosphere (dry deposition, wet deposition, air-surface exchange).
Currently, one of our main research thrusts revolves around fine dust. Designated as a Group 1 carcinogen by the WHO, fine dust comprises a diverse array of components, each with distinct emission sources, production pathways, and associated risks. Our aim is to comprehensively analyze both the inorganic and organic chemical constituents of fine dust to discern its emission sources, formation pathways, and potential mitigation strategies.
Moreover, we operate Kangwon National University Hospital and the Environmental Health Center to assess the impact of fine dust on respiratory diseases. Through rigorous investigation, we seek to quantify the influence of each fine dust component on respiratory ailments. Upon inhalation, fine dust triggers cellular inflammatory responses, yet the body's antioxidants can mitigate these adverse effects. To gauge the oxidative potential of fine dust and its impact on antioxidant depletion, ongoing research endeavors are underway.
Furthermore, our laboratory holds a particular interest in mercury, the only heavy metal capable of existing in a gaseous state. This unique attribute allows it to traverse multiple environmental media, including the atmosphere, water bodies, and soil, facilitating active movement. This means that multiple environmental medium can be actively moved. Mercury is a chemical that bioaccumulates up to 10 million times, and often shows high concentrations in the human body.
In particular, the blood mercury concentration of Koreans who consume a high amount of fish is on average very high. Recent studies in East Asia have focused on estimating and mapping mercury movement, encompassing emissions from soil, oceans, and vegetation into the atmosphere. Additionally, we have developed a passive sampler devoid of electricity requirements, enhancing our capacity for mercury monitoring and assessment.
