Analysis of 10 types of locally produced staple foods (including meat, fish, and eggs), provided estimates of dietary intakes of polybrominated diphenyl ethers (PBDEs) for residents of areas of Taizhou City (Zhejiang Province, Eastern China), which are long-established centers of rudimentary 鈥渆-waste鈥?recycling. Average 鈭慞BDE concentrations in chicken meat, eggs, and liver and duck meat and liver were among the highest recorded to date, with BDE-209 particularly abundant. The highest estimated contributions to 鈭慞BDE intake under a median exposure scenario were associated with adult consumption of duck eggs (3882 ng/day) and chicken eggs (1091 ng/day), and with consumption of fish by both adults (792 ng/day) and children (634 ng/day). Including estimates for ingestion of contaminated dust reported elsewhere increased median 鈭慞BDE daily intakes by approximately 19% for adults and 42% for children. Normalized to body weight, estimated median 鈭慞BDE exposures (from food and dust combined) were 130.9 ng/kg bw/day for adults and 614.1 ng/kg bw/day for children. High-end estimates of exposure for young children exceeded the U.S. Environmental Protection Agency reference doses for BDE-47 and BDE-99 by factors of approximately 2.5 and 1.5, respectively.
