Effects of spatial and temporal variation of acid-volatile sulfide on the bioavailability of copper and zinc in freshwater sediments Effects of spatial and temporal variation of acid-volatile sulfide on the bioavailability of copper and zinc in freshwater sediments
Variation in concentrations of acid-volatile sulfide (AVS) in sediments from the upper Clark Fork River of Montana, USA, was associated with differences in bioaccumulation of Cu and Zn and growth of larvae of the midge, Chironomus tentans. Growth of midge larvae was significantly greater and bioaccumulation of Cu was significantly less in surface sections (0–3 cm depth) of sediment cores...

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...

Delineation of flooding within the upper Mississippi River Basin—Flood of June 19-July 31, 1993, in Davenport, Iowa, and vicinity Delineation of flooding within the upper Mississippi River Basin—Flood of June 19-July 31, 1993, in Davenport, Iowa, and vicinity
The hydrologic investigations atlas shows areas in and near Davenport, Iowa, that were flooded by the Mississippi River in 1993. This atlas also depicts the Federal Emergency Management Agency 100-year flood boundary. The drainage basin upstream from Mississippi River Lock and Dam 15 at Davenport received between 100 and 250 percent of normal rainfall from January through July, 1993. The...
