Survey Of Amphibians And Reptiles In Powhatan County, Virginia With Selected Natural History Notes, Jason Daniel Gibson
Theses & Honors Papers
This thesis establishes baseline data on the herpetofauna that exist in Powhatan county. No systematic study of the amphibians and reptiles in Powhatan county has ever been conducted. The methods used in this survey include hand capture, egg mass observations, road kill collections, and frog call surveys. Documentation of each species collected included measurements, photographs, range maps, and tape recordings.
This survey produced 8 species of salamanders, 11 anurans, 6 turtles, 4 lizards, and 14 snakes. Based on records in the Atlas of Amphibians and Reptiles of Virginia (Mitchell & Reay, 1999), 11 new county records were discovered. This brings …

Development Of A Novel Method For Phenol Detection Using High Performance Thin Layer Chromatography, Danette Young Carlton
Theses & Honors Papers
The purpose of this study was to develop a more efficient method to test for phenol in both wastewater and non-wastewater. Phenol is a caustic and toxic contaminant that may be present in our water supplies. Phenol is used in various resins, pharmaceuticals, plastics and disinfectants. Environmental Protection Agency methods are available to test for phenol using gas chromatography along with mass spectrometry or flame ionization detection. Each of these methods can be a long, involved process consisting of extraction, many sample injections, and interference problems. This method developed an easier and less complicated approach of testing for phenol in …
