TLDR
In this paper, a series of polycyclic aromatic hydrocarbons (PAH) derived by early-diagenetic transformations of biogenic precursors are found in Recent sediments of four lakes ( Lake Lucerne, Lake Zurich, Lake Greifensee, and Lake Washington, northwest U.S.A.).About:

PAHs in the Fraser River basin: a critical appraisal of PAH ratios as indicators of PAH source and composition
Mark B. Yunker,Robie W. Macdonald,Roxanne Vingarzan,Reginald H. Mitchell,Darcy Goyette,Stephanie Sylvestre +5 more
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

Lacustrine organic geochemistry—an overview of indicators of organic matter sources and diagenesis in lake sediments
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).

Biomass burning — a review of organic tracers for smoke from incomplete combustion
TL;DR: In this paper, a brief review of the organic matter composition in aerosols derived from the major sources is also given, with emphasis on the detection of biomass burning components, and a long range transport of smoke particulate matter with the associated organic compounds is also discussed.
Journal ArticleDOI
Applications of organic geochemistry to paleolimnological reconstructions: a summary of examples from the Laurentian Great Lakes
TL;DR: The organic matter content of lake sediments contains information that helps to reconstruct past environmental conditions, evaluate histories of climate change, and assess impacts of humans on local ecosystems as discussed by the authors, and serve as proxies of organic matter delivery and accumulation.
Journal ArticleDOI
Evaluation of sediment contamination by polycyclic aromatic hydrocarbons in the Gironde estuary
TL;DR: In this paper, surface sediments, collected in the Gironde estuary during February and October 1993, were analysed for polycyclic aromatic hydrocarbons (PAHs) and the aromatic fractions were separated by liquid chromatography of the extracts and analysed by gas chromatography/mass spectrometry (GC/MS).

The global distribution of polycyclic aromatic hydrocarbons in recent sediments
Raymond Laflamme,Ronald A. Hites +1 more
TL;DR: The qualitative PAH pattern is remarkably constant for most of the locations studied, and the quantitative PAH abundance increases with proximity to urban centers as discussed by the authors, consistent with anthropogenic combustion's being the major source of these compounds.

Polycyclic aromatic hydrocarbons in the environment: homologous series in soils and recent marine sediments☆
W. W. Youngblood,Max Blumer +1 more
TL;DR: In this article, it is suggested that polycyclic aromatic hydrocarbons are formed in natural fires, are dispersed and mixed by air transport and eventually deposited into surface sediments.

Diterpenoid compounds and other lipids in deep-sea sediments and their geochemical significance
TL;DR: The presence of polycyclic diterpenoids with the abietane skeleton (mainly dehydroabietic acid) has been identified in sediment samples from the northeast Pacific Ocean, Black Sea, and North Atlantic Ocean as mentioned in this paper.
