Octanol-water partition coefficients (K OW ) of nine environmentally relevant brominated diphenyl ether (BDE) congeners present in two technical mixtures were directly measured using a slow-stir technique. LogK OW values of tri- to heptabrominated BDE congeners ranged from 5.74 to 8.27, and were related to bromine content by the equation logK OW =0.621(#Br)+4...
Ion source temperature, sample amount and the positions of the chlorine atoms attached to the neutral molecule all had profound effects on the appearance of the ECNI mass spectra of a number of synthesized polychloro-n-alkanes (PCAs). Increases in the ion source temperature resulted in a decrease in the abundances of both the [M + Cl] - and [M - Cl] - ions, while the abundances of...
