Selenium bioaccumulation and hazards in a fish community affected by coal fly ash effluent Selenium bioaccumulation and hazards in a fish community affected by coal fly ash effluent
Bioaccumulation of selenium (Se) in the fish community of Pigeon River/Pigeon Lake, which receives inputs of Se from a coal fly ash disposal facility, was studied to assess potential hazards of Se to fish, wildlife, and humans. Se concentrations in fish from sites receiving seepage and effluents from fly ash disposal ponds were significantly greater than those in fish from upstream...

Quality control considerations for the determination of acid-volatile sulfide and simultaneously extracted metals in sediments Quality control considerations for the determination of acid-volatile sulfide and simultaneously extracted metals in sediments
The determination of acid-volatile sulfide (AVS) and simultaneously extracted metals (SEMs) in sediment by treatment with dilute HCl shows promise as a tool for predicting the potential for metal toxicity to sediment-dwelling organisms. Effective quality control measures must be developed if this method is to become a reliable procedure and to ensure comparability of data. However...

Plant succession and greentree reservoir management: Implications for management and restoration of bottomland hardwood wetlands Plant succession and greentree reservoir management: Implications for management and restoration of bottomland hardwood wetlands
Bottomland hardwood forests are distributed along rivers and streams throughout the central and eastern United States, with the greatest concentration in the Southeast. Past and projected losses of bottomland hardwoods and degradation of remaining stands suggest that habitat management and/or restoration strategies that target multiple species and multiple uses will be necessary to...

In vivo/in vitro comparison of pharmacokinetics and pharmacodynamics of 3,3',4,4'-tetrachlorobiphenyl (PCB77) In vivo/in vitro comparison of pharmacokinetics and pharmacodynamics of 3,3',4,4'-tetrachlorobiphenyl (PCB77)
The rat hepatoma cell line, H4IIE, serves as a useful tool to assess potential biological effects such as induction of cytochrome P4501A1 expression. The objectives of this study were twofold: to investigate the kinetic time course and dosimetry of PCB77 in rat hepatoma cells dosed with PCB77 and in liver of rats given ip doses of PCB77, and to comparein vitroandin vivoP4501A1 enzyme...

Floods of June 17, 1990, and July 9, 1993, along Squaw Creek and the South Skunk River in Ames, Iowa, and vicinity Floods of June 17, 1990, and July 9, 1993, along Squaw Creek and the South Skunk River in Ames, Iowa, and vicinity
Water-surface-elevation profiles and peak discharges for the floods of June 17, 1990, and July 9, 1993, along Squaw Creek and the South Skunk River, in Ames, Iowa, are presented in this report. The maximum flood-peak discharge of 24,300 cubic feet per second for the streamflow-gaging station on Squaw Creek at Ames, Iowa (station number 05470500) occurred on July 9, 1993. This discharge...

Normalization of metal concentrations in estuarine sediments from the Gulf of Mexico Normalization of metal concentrations in estuarine sediments from the Gulf of Mexico
Metal concentrations were examined in sediments from 497 sites within the estuaries of the Gulf of Mexico by the United States Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP). Data were normalized for extant concentrations of aluminum to isolate natural factors from anthropogenic ones. The normalization was based on the hypothesis that metal...

Survey of users of the USGS stream-gaging network in Iowa, 1996 Survey of users of the USGS stream-gaging network in Iowa, 1996
A survey was sent to over 200 Federal, State, and local agencies that might use streamflow data collected by the U.S. Geological Survey in Iowa. A total of 181 forms were returned and 112 agencies indicated that they use streamflow data. The responses show that streamflow data from the Iowa USGS stream-gaging network, which in 1996 is composed of 117 stations, are used by many agencies...
