摘要： A total of 53 feeds from 23 brands for four types of animals, i.e., fish, chicken, duck, and pig, as well as six types of raw materials, were bought from Guangxi, Hubei, Anhui, and Guangdong provinces in China and analyzed for polybrominated diphenyl ethers (PBDEs). The raw materials including super fish meal, ordinary fish meal, poultry ore, soybean, stone powder, and rapeseed were selected because they were added to all the animal feeds manufactured. The occurrence of PBDEs was ubiquitous in the feeds and raw materials, with BDE-209 as the most abundant congener. The average concentration of Sigma 8PBDE was 1.1 and 0.44ngg(-1) dry weight in feeds (range 0.25-5.7) and raw materials (range 0.27-0.84), respectively. No statistically significant differences in Sigma 8PBDE concentrations were observed among the four groups of animal feeds. Feeds from Yangzhiyuan Brand (n=11) contained statistically (p<0.01) lower Sigma 8PBDE concentrations than all other brands except for Baoshun Brand. Chicken was selected as a representative animal to assess health risk for human exposure to PBDEs via the consumption of chicken raised by the feeds under investigation. Hazard quotients based on per-capita consumption of chicken were all below 1, indicating low potential risk to humans consuming chicken raised with the feeds.
