into quantitative structure-property relationship models for prediction of the photolysis half-life of PCBs

Yueping BAO, Qiuying HUANG, Wenlong WANG, Jiangjie XU, Fan JIANG, Chenghong FENG

Frontiers of Environmental Science & Engineering 2011, Volume 5, Issue 4,   Pages 505-511 doi: 10.1007/s11783-011-0318-2

Abstract: QSPR) models were developed for prediction of photolysis half-life ( ) of polychlorinated biphenyls (PCBsvalue for the optimal QSPR model is 0.966, indicating good prediction capability for lg values of PCBson a carbon atom ( ) and the standard heat of formation (Δ ) have a dominant effect on values of PCBsHigher values or lower Δ values of the PCBs leads to higher lg values.In addition, the lg values of PCBs increase with the increase in the energy of the highest occupied

Abstract: Homolog and congener profiles of polychlorinated biphenyls (PCBs), polychlorinated dibenzo- - dioxinsTotal concentration of PCDDs, PCDFs and dioxin-like PCBs (DL-PCBs) was found to be 740 ng TEQ/g, of which620 ng TEQ/g came from DL-PCBs.Three DL-PCBs congeners (i.e., #118, #156, #157) accounted for 77% of the total concentration of DL-PCBs, also they contribute 72% in the TEQ caused by DL-PCBs.

Determination of persistent organic pollutants by gas chromatography/laser multiphoton ionization/time-of-flight mass spectrometry

Osamu SHITAMICHI, Taiki MATSUI, Yamei HUI, Weiwei CHEN, Totaro IMASAKA

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 1,   Pages 26-31 doi: 10.1007/s11783-011-0374-7

Abstract: An authentic mixture of polychlorinated biphenyls was measured using a short wide-bore capillary column for the group separation of major components present in an actual sample of Kanechlor. The limits of detection were improved by ca. 2 fold in comparison with those obtained using a conventional capillary column, since the retention time was reduced and the amount of analytes introduced into the mass spectrometer per unit time could be increased. On the other hand, surface-water and sediment samples containing polycyclic aromatic hydrocarbons (PAHs) were collected from the river located in the vicinity of a waste water treatment plant. Even acenaphthylene, a minor component of the mixture could be measured for the sediment sample, and the concentrations were determined for several heavy PAHs. As demonstrated, a technique involving laser multiphoton ionization/time-of-flight mass spectrometry was useful as a sensitive and selective analytical tool for the trace analysis of persistent organic pollutants in an environmental sample.
