Abstract:
... The movement of contaminants through subsurface is usually a complex phenomenon. As such, contaminant–soil interaction is important to assess the fate and transport of contaminants through the soil as well as groundwater flow systems. Thus, laboratory-scale columns are pertinent tools for studying the release potential of hydrophobic organic contaminants from soil or waste materials. Herein, a lab ...

Several halogenated flame retardants (HFRs) have been identified as thyroid disruptors in birds including the polybrominated diphenyl ether (PBDE) mixtures, which have been replaced with other HFRs such as Dechlorane-604 (Dec-604). Dec-604 Component B (Dec-604 CB), a putative debrominated product of Dec-604, has been frequently reported in urban-adapted ring-billed gulls (Larus delawarensis) breed ...
