The PAH hypothesis: a computational experiment on the combined effects of ionization and dehydrogenation on the IR signatures
IR spectra of anthracene and pyrene derivatives, serving as models for isolated, linear and isolated, compact PAHs, respectively, have been calculated using ab-initio quantum mechanical methods. The separate and combined effects of ionization and multiple dehydrogenation have been studied. This study confirms and refines the trends of our preliminary paper on the smallest possible PAH, naphthal...
متن کاملPAH Exposure
A 140 volume 117 | number 4 | April 2009 • Environmental Health Perspectives PAH Exposure doi:10.1289/ehp.0800445 We were very interested to read the article by Choi et al. (2008). The difference between maternal exposure and our own data on actual concentrations of poly cyclic aromatic hydro carbons (PAHs) in the human male fetal liver (Fowler et al. 2008) was striking. Eight of the PAH exposu...
متن کاملSimulated infrared emission spectra of highly excited polyatomic molecules: a detailed model of the PAH-UIR hypothesis.
A detailed description of the polycyclic aromatic hydrocarbon (PAH)/unidentified infrared band (UIR) mechanism is presented in which experimental spectral bandshape functions are used to simulate IR emission spectra for individual molecules. These spectra are additively superimposed to produce a conglomerate spectrum representative of a family of PAH molecules. Ab initio vibrational frequencies...

Value of Monitoring Serum Immunoglobulins Questioned Our journal club's review of the recent article by Szczeklik al. (EHP 102:302304) found fault on many levels, especially with the concluding recommendation. It would be neither practical nor useful for workers exposed chronically to PAHs to have serum immunoglobulin levels monitored regularly. The use of cross-sectional data regarding serum i...
متن کاملWalking the tightrope of bioavailability: growth dynamics of PAH degraders on vapour‐phase PAH
Microbial contaminant degradation may either result in the utilization of the compound for growth or act as a protective mechanism against its toxicity. Bioavailability of contaminants for nutrition and toxicity has opposite consequences which may have resulted in quite different bacterial adaptation mechanisms; these may particularly interfere when a growth substrate causes toxicity at high bi...
