Atmospheric levels of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) were measured around the Tampa Bay area. Total PCBs, Î£56PCBs, ranged from 41.96- 1250.96 pg/m3 and total PBDEs, Î£14PBDEs, ranged from 0.78-9.54 pg/m3 at 5 sites with unique land-use classifications. PCB congener profiles indicated significant differences between most sites while PBDE congener profiles were more uniform. The use of Zero Valent Metals (ZVM) to remediate PBDEs was also explored. In a five hour study 0.8% Mg/Pd bimetallic system showed a 99% degradation of BDE-47 (2,2â€™,4,4â€™- tetrabromodiphenyl ether), following a step-wise debromination path with pseudo 1st order kinetics.
