Solubility Enhancement Data
Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardant that is distally transported to the arctic. Little is known about the fate of PBDEs in arctic surface waters, especially in the presence of dissolved organic matter (DOM). DOM has been shown to interact with hydrophobic...

Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardant that is distally transported to the arctic.
