Persistence Of Trace Organic Contaminants From A Commercial Biosolids-Based Fertilizer In Aerobic Soils, Travis A. Banet, Jihyun R. Kim, Michael L. Mashtare
Persistence Of Trace Organic Contaminants From A Commercial Biosolids-Based Fertilizer In Aerobic Soils, Travis A. Banet, Jihyun R. Kim, Michael L. Mashtare
The Summer Undergraduate Research Fellowship (SURF) Symposium
Municipal biosolids are recycled as agricultural fertilizers. Recent studies have raised concerns due to the presence of emerging contaminants in municipal biosolids. Previous research suggests that these contaminants have the potential to reside in biosolids-based fertilizers that are commercially distributed. Use of these products in urban/suburban areas may provide a pathway for these contaminants to enter ecosystems and impact human and environmental health. Soils from Purdue University’s community garden and MiracleGro Potting Mix were chosen to represent commonly used urban/suburban growth media. Triclosan, triclocarban, and methyl parabens were selected as compounds of interest for this study. A heat treated commercial …

Thiophene Based Molecular Sensors Towards Mercury Detection, Austin K. Shigemoto, Carolyn N. Virca, Sam Underwood, Lauren Shetterly, Theresa M. Mccormick
Student Research Symposium
Toxic heavy metals such as mercury have increased in concentration in the environment due to pollution. Inorganic mercury in the environment can be later converted to a more toxic form: methylmercury. Regular consumption of fish containing methylmercury can lead to several cognitive and motor disorders as well as Minamata disease. The current methods used to detect both methylmercury and inorganic mercury in sea life and drinking water involve long sample preparation and cost. In order to more efficiently track this toxic metal in the environment and identify contaminated food and water sources, a cheaper and faster method of detection is …
Evaluation Of The Performance Of A Rural Surface Water Treatment Plant In Nacogdoches, Texas, Esmeralda Garcia, Jennifer Hanes, Phillip Sharp, Petra Kadakova, Kefa Karimu Onchoke, Michael Janusa
Evaluation Of The Performance Of A Rural Surface Water Treatment Plant In Nacogdoches, Texas, Esmeralda Garcia, Jennifer Hanes, Phillip Sharp, Petra Kadakova, Kefa Karimu Onchoke, Michael Janusa
Undergraduate Research Conference
The performance of a rural surface water treatment plant in Nacogdoches Texas was assessed for selected metals (Ag, Ba, Be, Bi, Cd, Co, Cr, Cs, Cu, Ga, In, Li, Mn, Mo, Ni, Pb, Rb, Sr, Tl, V, and Zn) from June 2015 through spring 2016. Results indicate that the lake water coming into the surface water treatment plant was significantly cleaner after treatment and was below maximum World Health Organization (WHO) drinking water standards.
