Bioaccumulation and Toxicokinetics of Polycyclic Aromatic Compounds and Metals in Giant Floater Mussels (Pyganodon grandis) Exposed to a Simulated Diluted Bitumen Spill
… This thesis identifies the bioaccumulating compounds derived from naturally weathered dilbit in adult giant floater mussels (Pyganodon grandis), to determine the rates at which they were accumulated and excreted. More specifically, the bioaccumulation potential and toxicokinetic parameters …

The acid-catalyzed self-condensation reaction of b-diketones in the presence of 2,2,2-trifluorodiazoethane
… for the preparation of cyclized products (e.g., aromatic natural products) from 6-dicarbonyl units. Acid-catalyzed reactions of 1-phenyl-1,3-butanedione and several substituted derivatives of 1- phenyl-1,3-butanedione with TFD afforded two groups of substituted biphenyl compounds. One of these …

Photochemical Reaction Products of Polycyclic Aromatic Hydrocarbons Adsorbed at an Air-Water Interface
Polycyclic aromatic hydrocarbons (PAH) are ubiquitous pollutants resulting from incomplete combustion and hence normally unavoidable. The kinetic aspects of the environmental degradation process have received considerable attention; however, not much is known about the degradation products …

New Developments On High-resolution Luminescence Spectroscopy And Their Application To The Direct Analysis Of Organic Pollutants
Polycyclic aromatic compounds (PACs), which comprise a complex class of condensed multi-ring benzenoid compounds, are important environmental pollutants originating from a wide variety of natural and anthropogenic sources. PACs are generally formed during incomplete combustion of pyrolisis of …

Profiling the Organic Emissions from a Light-Duty Direct Injection Diesel Engine over a range of Speeds and Loads
… of the particulates in urban city environments. Polycyclic aromatic compounds (PAC), some proven carcinogens, have been found on diesel particulates. The trace level nitro-PAC emissions, such as 1-nitropyrene and dinitropyrenes, contribute a large proportion of the mutagenicity in the …
