Pesticides in the Great Lakes
Pesticides have been widely and heavily used in agriculture in the Great Lakes Basin (approximately 93000 tons were used in 1995 alone). Herbicides...

Degradation and Preservation of Organic Matter in Marine Sediments
Organic matter that is deposited in aquatic sediments is subject to an intense diagenetic reactor that determines how much organic carbon is...
-
Brominated Flame Retardants in the Great Lakes
Brominated flame retardants in the Great Lakes have not been as well studied as many of the polychlorinated pollutants, especially PCBs, but in the...
-
Polychlorinated Biphenyls in the Great Lakes
This chapter reviews the scientific understanding of the concentrations, trends, and cycling of polychlorinated biphenyls (PCBs) in the Great...

Plant roots affect free-living diazotroph communities in temperate grassland soils despite decades of fertilization
Fixation of atmospheric N 2 by free-living diazotrophs accounts for an important proportion of nitrogen naturally introduced to temperate grasslands....

Controls on the Carbon Isotopic Compositions of Lipids in Marine Environments
Organic carbon isotopes have long been used to study modern and ancient biogeochemical processes. Controls on the isotopic composition of organic...
-
Sources and Cycling of Organic Matter in the Marine Water Column
The organic carbon cycle operates on multiple time scales with a only small fraction of the global reservoir actively exchanged. For the marine...

Polychlorinated Naphthalenes in the Great Lakes
This review examines the sources and occurrence of polychlorinated naphthalenes (PCNs) in the Great Lakes environment and summarizes current...
-
Sources and Fate of Organic Contaminants in the Marine Environment
The sources, levels, and fate of organic contaminants of major concern in the marine environment are reviewed. Spatial distributions among the...
-
Perfluorinated Compounds in the Great Lakes
Perfluoroalkyl acids (PFAs) are released to the environment via their manufacturing processes, their use in commercial products, or indirectly via...
-
Lipid Markers for Marine Organic Matter
An astonishing variety of different lipids have been found in marine sediments and the water column attesting to the diversity of biosynthetic...
-
Pigment Markers for Phytoplankton Production
Chlorophylls and carotenoids are commonly used as quantitative biomarkers for the composition and biomass of marine phytoplankton. This chapter...
-
Isotopic Tracers of the Marine Nitrogen Cycle: Present and Past
The oceanic nitrogen cycle consists of a web of microbially mediated transformations driven in part by the large range in possible nitrogen...
