Polychlorinated biphenyls algae

DDT (trace A) and its metabolites DDE and DDD (trace B), and traces F and G are the commercial polychlorinated biphenyl (PCB) mixtures Arochlor 1242 (trace F) and Arochlor 1254 (trace G). As is illustrated, extracts of local Laurencia species (traces C and D), and the extract of a halogenating bacterium Chromobacterium sp. (trace E), contain compounds of similar retention time to DDT and its metabolites. Traces H and J were produced from extracts of Plocamium cartilagineum and Chondria californica, two locally abundant red algae, and trace I was produced from a species unidentified sponge of the genus Verongia. In this case mixtures of halogenated natural compounds fall within the limits of detectability of the PCBs. [Pg.390]
