Interpretive Summary: Polybrominated diphenyl ethers (PBDEs) are flame retardants which have been found to be increasing in the environment and in marine life. These compounds show structural similarities to the polychlorinated biphenyls but are currently not associated with any known health risks. In order to determine if livestock may be exposed to this class of compounds, we have developed methods to analyze chicken fat samples for PBDEs. The method detected mono- to deca-substituted BDEs at the part per billion level. PBDEs were found in most chickens sampled; the levels varied from location to location. In most cases the levels were much lower than those found in fish and fish-eating mammals. However, at two locations in the Southern U.S., chickens had levels similar to levels reported in seals from the Arctic.

Technical Abstract: Polybrominated diphenyl ethers (PBDEs) are flame retardants which have been found to be increasing in the environment. Structural similarities to the polychlorinated biphenyls have caused concerns that PBDEs may pose health risks to biota. A GC-MS method was developed to analyze mono- through deca-BDEs in chicken fat samples. The method utilized GC pressure programming and selected ion monitoring to quantitate PBDEs at the low part per billion level. Four 13C-labelled BDE surrogates were used to determine recoveries which averaged from 76-114%. Thirteen chickens from the Southern U.S. and a composite sample of chickens from North Dakota were analyzed by this methods. The total concentrations of PBDEs on a whole weight basis ranged from 1.7 ppb in North Dakota chickens to 39.4 ppb in a chicken from Arkansas. Chickens from North Dakota had levels similar to background blanks. Chickens from the Southern U.S. had higher levels than blanks. On a lipid weight basis, these levels were lower than those generally found in fish and fish- eating mammals. The PBDE pattern was also different from other samples reported; penta-BDEs rather than tetra-BDEs were the most prominent congeners.
