In this study, the dietary exposure to seven polybrominated diphenyl ethers (PBDEs) congener groups, including 22 types of PBDEs compounds, through consumption of 80 food items in Korean diets along with their risk assessment has been investigated. To process this, the concentrations of the target PBDEs in samples of food items were measured. The consumption amounts of the target food items were derived from the results of the 24 h food recall interview of subjects who participated in the Korean National Health and Nutrition Examination Survey (KNHANES) from 2015 to 2019. Thereafter, the estimated daily intake and risk of exposure for each PBDEs congener group were assessed. Results indicate that although exposure to the target PBDEs was not significant enough to cause a potential health risk, deca-BDE (BDE-209) was the dominant congener in terms of both exposure and risk for consumers in all age groups. Furthermore, while eating seafood was the dominant path for dietary exposure to PBDEs, exposure to octa-BDEs was mostly through livestock products. Accordingly, to protect all consumers, especially those aged below 2 years and over 65 years, more accurate food quality management is required for controlling the dietary intake of PBDEs.
