| comparing polybrominated diphenyl ether and polychlorinated biphenyl bioaccumulation in a food web in grand traverse bay, lake michigan. | levels of polybrominated diphenyl ethers (bdes) in great lakes salmonids and ambient air have been recently reported, but few studies worldwide have examined the accumulation of bdes within aquatic food webs. here we report some of the first measurements of six bde congeners that are common components of the pentabde commercial mixture within an entire lake michigan food web. bdes were detected in all samples and the dominant bde congener was 2,2',4,4'-tetrabromodiphenyl ether (bde 47). bde 47 l ... | 2003 | 14565581 |
