Title: Geographic trends in contamination of Nebraska's surface waters as indexed by sex steroids of common carp
Project Type: Research
Start Date: 3/01/2008
End Date: 2/28/2009
Congressional District: 1 & 2
Focus Categories: Non Point Pollution, Ecology, Surface Water
Keywords: steroidogenic contaminants, lentic systems, fish
Principal Investigators: Pope, Kevin Lee (University of Nebraska--Lincoln); Kolok, Alan S; Snow, Daniel
Federal Funds: $ 14,440
Non-Federal Matching Funds: $ 29,099
Abstract: The specific objective of this project is to document occurrence and concentrations of steroidogenic contaminants in water from 20 lakes and reservoirs throughout Nebraska and examine geographic variation in effects of sex steroids on adult common carp. We hypothesize that sex steroid profiles will vary considerably across the state, and will be associated with bioavailability of steroidogenic compounds within each water body. If correct, this study will provide preliminary data and direction for proposals geared at the USGS 104 G and US EPA STAR programs to access potential risks associated with contamination of surface waters, which was identified by UNL Water Center and Water Resources Research Initiative as a top 10 water challenge for Nebraska.
