Contaminant Biology
Data and Tools
The Environmental Health Program (Contaminant Biology and Toxic Substances Hydrology) generate environmental contaminant and pathogen, toxicity, and effects data. All of which is provided to the public in our publications and data sets.
Data for Understanding the captivity effect on invertebrate communities transplanted into an experimental stream laboratory
Little is known about how design and testing methodologies affect the macroinvertebrate communities that are held captive in mesocosms. To address this gap, we conducted a 32-day test to determine how seeded invertebrate communities changed once removed from the natural stream and introduced to the laboratory. We evaluated larvae survival and adult emergence in controls from 4 subsequent...
Amphibian Occupancy and Effects of Habitat Use on Pesticide Exposure in Iowa Wetlands
Amphibians living in agricultural areas encounter many challenges. Two factors affecting individuals in these landscapes are habitat loss and pesticides. This thesis focuses on amphibians using agricultural wetlands in Iowa, where row crops such as corn and soybeans dominate the landscape. The goal of my first study was to determine the influences of site characteristics on amphibian presence...
2004-2010 Chesapeake Bay Smallmouth and Largemouth Bass Estrogenic Biomarker Data
The data was gathered to document the extent and severity of biomarkers of exposure to estrogenic chemicals in smallmouth and largemouth bass. Samples were collected from 2004 through 2010 at sites in five watersheds within the Chesapeake Bay watershed. A total of 281 largemouth bass were collected from the Potomac, Susquehanna, Patuxent and Rappahannock rivers and 1,384 smallmouth bass fro...
Estrogen Equivalents of Surface Water in the Upper Chesapeake Bay Watershed (2008 - 2011)
Intersex in small- and largemouth bass has been observed in the upper Chesapeake Bay Watershed since 2003. This observation is indicative of exposure to estrogenic endocrine disrupting chemicals. In order to complement biological data sets and better identify the spatial and temporal nature of this end-point, discrete grab water samples were collected throughout the upper Chesapeake Bay...
