Abstract Nanjing Chemical Industry Park (NCIP) is an important industrial base with more than 300 chemical plants. Taking NCIP as a research area, this article conducted a random sampling survey on the aquatic product consumption of residents in the NCIP and its surrounding areas. Then this study preliminarily estimated the exposure level of local residents to polybrominated diphenyl ethers (PBDEs) associated with fish consumption. The mean intake of Σ6 PBDEs via fish consumption was 0.69 ng/kg body weight b.w./day with a range of 0.35-1.63 ng/kg b.w./day. There was no significant difference in total intake of PBDEs at different body weights. Among the six PBDEs congeners, BDE-47 was dominant in the total intake, with an average contribution rate of 77%. The daily exposure to PBDEs decreased with the increase of body weight. During this period, the total intake of PBDES through fish consumption was at a low level. Overall, the estimated daily intake of total PBDEs was far below the LOAEL for the population in this region.
