퇴적물 내 페놀류 정량을 위한 USEPA 분석법 개선 및 최적화

초록

Phenolic compounds are generated from various industrial activities and natural processes, accumulating in marine sediments where they pose significant threats to ecosystems and human health. Despite their high toxicity and low environmental persistence, these compounds can accumulate at high concentrations over short periods, contributing to ongoing environmental contamination. This study improves and optimizes existing analytical methods, including USEPA 8270D, 3540C, and 3630C, for the quantitative analysis of phenolic compounds in marine sediments. To address limitations in the purification step of the analysis, experiments with various solvents were conducted, identifying 50% dichloromethane/ethyl acetate as yielding the highest recovery rates and the most stable analytical results. The optimized method was applied to sediment samples from coastal areas of Busan and Ulsan. Additionally, QA/QC procedures ensured the method's high reliability and reproducibility. This method can be used to evaluate long-term accumulation trends of phenolic compounds in the marine environment and to establish effective pollution management strategies. The findings of this study provide reliable foundational data on phenolic compounds for monitoring marine pollution and establishing regulatory standards.
