Do Environmental Toxins Predict Violent Crimes?, Tyler Stahl
Do Environmental Toxins Predict Violent Crimes?, Tyler Stahl
Symposium of Student Scholars
Do chemical pollutants that persistent in the environment and bioaccumulate in the body affect human health and behavior? Could these Persistent, Bioaccumulative, and Toxic (PBT) chemicals play a role in the cause of violent crimes due to deterioration of mental and cognitive functions? In the past, Mercury, a PBT chemical, has been shown in salmon to be associated with aggression. Could similar aggression occur in humans exposed to mercury through a toxic spill? Two sources of data are utilized in this analysis. The Environmental Protection Agency’s (EPA) Annual Toxic Release Inventory publishes data on toxic releases into the environment and …

Do Tropical Storms Have An Effect On Water Quality In Nacogdoches?, Emmie Schubert, Breanna Duran, Jaqui Murguia, Amy Rambo, Paige Graham
Do Tropical Storms Have An Effect On Water Quality In Nacogdoches?, Emmie Schubert, Breanna Duran, Jaqui Murguia, Amy Rambo, Paige Graham
Undergraduate Research Conference
The purpose of this research was to determine the effects tropical storms had on the water quality of water in Nacogdoches. This research investigated if rainwater distributed during the storms affected the levels of pH, nitrate, nitrite, phosphorous, alkalinity, turbidity, and total dissolved solids (TDS). Sampling was conducted on three water bodies before and after the storms. Measurements were taken with LaMotte kit to measure alkalinity, turbidity tube to measure turbidity, Colorimeter to test the nutrient levels, and Multi-Parameter Tester to measure TDS and pH. The results showed that Laura had a greater impact than Beta. Tropical storms are unforeseeable, …
Revegetation Of Native Plant Communities In Great Salt Lake Wetlands: The Effects Of Native Seed Mix Composition And Sowing Density, Laura Beck
Student Research Symposium
One of the threats currently facing Great Salt Lake wetlands is Phragmites australis. Its rapid expansion since 1987 has displaced native vegetation and changed the composition of plant communities. Removal is very costly and takes multiple years of different treatments like herbicide, mowing, and flooding. To ensure Phragmites australis does not return, native seeds will need to be sown. This experiment is to determine the best seed composition and sowing density. In the USU greenhouse, I will sow four different native seed mixes: 100% desirable perennial natives, 75% perennial natives and 25% fast growing natives, 50% perennial natives and 50% …
