Organic Geochemistry 

TL;DR: In this paper, parent and alkyl PAHs were quantified in suspended particulates and sediments (345 samples) from the Fraser River system, British Columbia, Canada, and the best potential to distinguish natural and anthropogenic sources is exhibited by ratios of the principal mass 178, 202, 228 and 276 parent PAH, 1,7/2,6+1,7-DMP (dimethylphenanthrene), the phenanthrene/anthracene and fluoranthene/pyrene alkyal PAH series and several less commonly applied PA

TL;DR: In this article, the organic matter content of sediments is inferred from bulk properties such as elemental compositions, carbon and nitrogen stable isotope ratios, Rock-Eval pyrolysis data, and organic petrography.

TL;DR: It is indicated that inferences drawn from sterol distributions regarding sources of organic matter must be made with caution and should be supported using other lipid data, and that in ancient sediments and crude oils a high proportion of C 29 steranes need not indicate that most of the organic matter was derived from vascular plants.

TL;DR: In this paper, the authors review the design considerations faced by the developers of fast pyrolysis, upgrading and utilisation processes in order to successfully implement the technologies and provide a case study of the application of the technology to waste wood and how this approach gives very good control of contaminants.

TL;DR: The factors affecting the amounts and types of organic matter in lacustrine sediments are summarized in a review, and synthesis, of published studies as discussed by the authors, and the interplay of the factors influencing the organic matter content of lake sediments is illustrated by overviews of sedimentary records of four lake systems--Lake Biwa (Japan), Lake Greifen (Switzerland), Lake Washington (Pacific Northwest), and the Great Lakes (American Midwest).
