Abstract Details

2008, MS, University of Cincinnati, Arts and Sciences : Biological Sciences.
Polybrominated diphenyl ethers (PBDES) are emerging contaminants commonly used as fire retardants. Their use in a wide variety of products has made them ubiquitous in the environment. PBDEs similarity to other pollutants suggests they will persist in the environment. Little research has been done on actual mechanisms affecting PBDE presence in the environment. Sorption of PBDEs in aging soil systems was studied. Soil composition was not a determinant of sorption. Sorption to soils was reversed by biotic effects of microorganisms and plants. Biodegradation of PBDEs was also examined using sewage bacteria. Rapid degradation of PBDEs was seen in some organisms. While biotic potential for mobilization and degradation of PBDEs exists, their presence in the environment is still increasing. Sorption to soil appears to be the dominant process controlling the fate in the environment.
