A field screening method for polychlorinated biphenyl compounds in water
The objective of this study was to develop a simple, inexpensive and rapid procedure for determination of PCBs in water. There was special interest in developing a field-screening procedure for aqueous extracts resulting from a soil remediation procedure; the extracting liquid typically contains …

The acid-catalyzed self-condensation reaction of b-diketones in the presence of 2,2,2-trifluorodiazoethane
… with TFD afforded two groups of substituted biphenyl compounds. One of these groups could be an important synthon for the preparation of larger polycyclic aromatic compounds. Several cyclized products have also been obtained from the reaction of 2, 4-pentanedione with TFD. Two potential …

Investigation of polyethlyene passive samplers' efficacy in deducing sediment pore water concentrations of PCBs
Polychlorinated biphenyl compounds (PCBs) were manufactured between 1929 and 1977 as heat exchange fluids, flame retardants, and pesticide extenders, among other uses. About 450 million pounds of PCBs are estimated to have entered the environment since manufacture. Assessing the hazard posed by …
