Water quality and trophic status of Fort Cobb Reservoir, southwestern Oklahoma, 2016: Chapter 8 in Assessment of conservation practices in the Fort Cobb Reservoir watershed, southwestern Oklahoma Water quality and trophic status of Fort Cobb Reservoir, southwestern Oklahoma, 2016: Chapter 8 in Assessment of conservation practices in the Fort Cobb Reservoir watershed, southwestern Oklahoma
Eutrophication of reservoirs frequently occurs because of excessive nutrient inputs caused by anthropogenic activities, including row-crop agriculture. The trophic status of Fort Cobb Reservoir, Oklahoma, was assessed in April, July, and September 2006. The Fort Cobb Reservoir was highly eutrophic, with the greatest concentrations of nutrients and chlorophyll-a being measured in the...

Accumulation of environmental contaminants in wood duck (Aix sponsa) eggs, with emphasis on polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans Accumulation of environmental contaminants in wood duck (Aix sponsa) eggs, with emphasis on polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans
We measured polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), polychlorinated biphenyls (PCBs), organochlorine pesticides, and mercury in wood duck (Aix sponsa) eggs collected near a North Carolina (USA) bleached kraft paper mill. Samples were taken a decade after the mill stopped using molecular chlorine. Using avian toxic equivalency factors, 2,3,7,8

Chemical contaminants, health indicators, and reproductive biomarker responses in fish from rivers in the Southeastern United States Chemical contaminants, health indicators, and reproductive biomarker responses in fish from rivers in the Southeastern United States
Largemouth bass (Micropterus salmoides) and common carp (Cyprinus carpio) were collected from 13 sites located in the Mobile (MRB), Apalachicola–Flint–Chattahoochee (ARB), Savannah (SRB), and Pee Dee (PRB) River Basins to document spatial trends in accumulative chemical contaminants, health indicators, and reproductive biomarkers. Organochlorine residues, 2,3,7,8-tetrachlorodibenzo-p...

Distribution of pesticides, PAHs, PCBs, and bioavailable metals in depositional sediments of the lower Missouri River, USA Distribution of pesticides, PAHs, PCBs, and bioavailable metals in depositional sediments of the lower Missouri River, USA
The lower Missouri River was studied to determine the distribution of selected persistent organic pollutants and bioavailable metals in depositional sediments. Nineteen sites between Omaha, Nebraska and Jefferson City, Missouri were sampled. This stretch of the river receives point-source and non-point-source inputs from industrial, urban, and agricultural activities. As part of an...
