(2012-07-16)Windblown dust is a significant source of sediment and organic matter for many basins, but its influence on ancient basins can be difficult to detect and quantify. We quantified the biomarker content, including n-alkanes, ...
-
(2019-05-28)This study represents a detailed analysis of the biochemical composition of organic carbon (OC) preserved in coastal wetland systems. Coastal wetlands are sensitive to anthropogenic disturbances with habitats undergoing ...
-
(2011-10-21)The need to assess human exposures to foodborne and environmental carcinogens, particularly in populations at high risk for cancer and disease, has led to the development of chemical-specific biomarkers. Sensitive biomarkers ...
