研究室紹介
Professor Jae-yoon Choi's research lab specializes in environmental health and exposure science, focusing on identifying and assessing chemical hazards from consumer products and environmental sources. The lab investigates human exposure to volatile organic compounds (VOCs) and heavy metals through integrated approaches such as passive sampling, biomonitoring, and field measurements. Key research directions include indoor air quality, chemical migration from plastic food contact materials, and algal bloom monitoring using fluorescence-based indicators like phycocyanin. The lab emphasizes real-world exposure assessment to support public health risk evaluation and policy development.

3Consumer products are significant contributors to indoor volatile organic compound (VOC) emissions, with oil‐based wood stains, commonly used in do‐it‐yourself (DIY) projects, being particularly notable sources. This study was aimed at evaluating personal exposure to VOCs during DIY application of oil‐based wood stains by integrating passive sampling, dermal exposure assessment, and urinary biomonitoring. Twenty‐two volunteers wore a validated expanded polytetrafluoroethylene passive sampler (eP
Objectives:The purpose of this study is to provide basic data for the development of a rapid and easy to measure alternative indicator for estimating the number of cyanobacteria cells in the field.Methods:Phycocyanin, algal cell number, and water quality items were measured at the left, middle, and right points of Maery Bridge near the Mulgeum and Maery algae monitoring network located downstream of the Nakdong River. The phycocyanin concentration(PC) was measured in the field using the LISST-HA
Heavy metals can be intentionally or unintentionally introduced into plastic food utensils, containers, and packaging (PFUCP) as additives or contaminants, which can be ingested with food by humans. Here, seven-heavy metals (lead, cadmium, nickel, chromium, antimony, copper, and manganese) with toxicity concerns were selected, and risk assessment was done by establishing their migration from 137 PFUCP products made of 16 materials distributed in Korea. Migration of heavy metals was examined by a
