Discovery and widespread occurrence of polyhalogenated 1,1'-dimethyl-2,2'bipyrroles (PDBP's) in marine biota
Polyhalogenated 1,1'-dimethy1-2,2'-bipyrroles (PDBPs) are halogenated natural products (HNPs) previously shown to bioaccumulate in marine mammals and birds. Since their discovery in 1999, six hexahalogenated and a few lesser halogenated congeners have been identified in diverse marine mamm...
