Unusual hepta‐ and octabrominated diphenyl ethers and nonabrominated diphenyl ether profile in California, USA, peregrine falcons ( Falco peregrinus): More evidence for brominated diphenyl ether‐209 debromination
Abstract High (maximum of 4.1 ppm lipid weight) levels of BDE‐209 and other higher brominated diphenyl ethers (BDEs) found in California, USA, peregrine falcon ( Falco peregrinus ) eggs (n = 95) provided an opportunity to examine homolog profiles of nona‐, octa‐, and hepta‐BDEs as possible evidence...
