Polybrominated diphenyl ethers (PBDEs) are still present in sewage sludge and sludge amended soil, even though commercial PBDEs were prohibited or voluntarily phased out several years ago. In this study, levels and compositional profiles of seven major PBDE congeners in s lud ge are assessed in relation to their usage patterns in commercial products, and years of being banned and phased out in Asia. Annual accumulations long term changes of PBDE in sludge amended soil are estimated. BDE 209 has the highest concentration, followed by BDE 99 and BDE 47. The estimated concentrations of BDE 47 , BDE 99, and BDE 209 in the soil after receiving 15 year sludge applications are 40~300 times higher than their initial concentrations |
