나 교수의 연구실은 생분해성 플라스틱과 환경 오염물질이 수생 생태계에 미치는 복합적 영향을 중심으로 연구를 진행하고 있습니다. 특히 생분해성 마이크로플라스틱(PLA)과 농약, 자연 유기물 등 다양한 오염물질이 상호작용하는 메커니즘과 그 생물학적 영향을 Daphnia magna를 모델 생물로 분석하고 있습니다. 또한 산업 폐수에서 발생하는 유해 물질(예: 아연)의 기원과 그 독성 메커니즘을 규명하기 위한 독성 정밀 분석(TIE) 및 Fenton 반응의 영향을 연구하고 있습니다.

Biodegradable plastics (BPs) are widely used as alternatives to non-BPs due to their inherent ability to undergo facile degradation. However, the ecotoxicological impact of biodegradable microplastics (MPs) rarely remains scientific documented especially to aquatic ecosystem and organisms compared to conventional microplastics. Therefore, this study aimed to investigate the ecotoxicity of biodegradable polylactic acid (PLA) MPs to Daphnia magna with that of conventional polyethylene (PE) MPs wit
This study aimed to identify the source of toxicity in textile dyeing effluent collected from February to July 2016, using Daphnia magna as a test organism. Toxicity identification evaluation (TIE) procedures were used to identify the toxicants in textile dyeing effluent, and Jar testing to simulate the Fenton process was conducted to identify the source of toxicants. Textile dyeing effluent was acutely toxic to D. magna [from 1.5 to 9.7 toxic units (TU)] during the study period. TIE results sho
The proliferation of biodegradable plastics like polylactic acid (PLA) necessitates a deeper understanding of their ecotoxicological impacts, particularly their interactions with co-existing pollutants in aquatic ecosystems. This study investigates the combined toxicity of PLA microplastics (MPs), the insecticide diflubenzuron (DFB), and the influence of natural organic matter (NOM) on the freshwater cladoceran Daphnia magna. Acute 48-hour exposures were conducted to assess mortality, while subl
