Endocrine Disruption In Largemouth Bass (Micropterus Salmoides) From A Pcb-Contaminated Reservoir, Stephanie B. Laplaca

Theses and Dissertations

There are numerous cases of intersex condition in fish, specifically immature oocytes in testicular tissue, documented in recent literature. Typically, these cases identify a point source input of endocrine disrupting compounds impacting the fish, such as wastewater treatment effluent. Legacy contaminants such as polychlorinated biphenyls (PCBs) have been suggested as endocrine disruptors in fish species. The objective of this study was to assess endocrine disruption in wild largemouth bass (Micropterus salmoides) from exposure to PCBs at a Superfund site in South Carolina on Lake Hartwell (SV-107), where high levels of PCBs in sediment and fish tissue samples have been detected …

Prenatal Methylmercury Exposure In A South Carolina Coastal Cohort, Alexis Donohue

Theses and Dissertations

Objectives: Methylmercury is a neurotoxin that has the ability to cross the placenta and adversely affect the developing fetus. Our primary objective was to investigate whether prenatal methylmercury exposure varied longitudinally, and whether differences were associated with maternal characteristics.

Methods: Pregnant mothers were recruited in Charleston, South Carolina (8-17 weeks gestation) (n=78). Blood samples were collected during both early (11.8 ± 1.7 weeks) and late (35.3 ± 2.0 weeks) gestation. Blood total mercury and methylmercury concentrations were analyzed. Upon enrollment in the study, mothers filled out a sociodemographic questionnaire that included questions regarding maternal age, race/ethnicity, and education level. Additionally, …

Socio-Cognitive Factors And Perceived Consequences Associated With Alternative Forms Of Alcohol Use, Abbly L. Braitman, Ashley N. Linden-Carmichael, Amy L. Stamates, Cathy Lau-Barraco

Psychology Faculty Publications

Objective: Popular media have highly publicized alternative forms of alcohol use (eg, eyeballing, inhaling alcohol vapor) among college students as a growing concern, possibly associated with severe health risks. Formative research indicates rarity of use.

Participants and Methods: College students (Study 1: n = 411; Study 2: n = 687) completed an online survey.

Results: Findings confirmed infrequent use of alternative methods of alcohol use and low likelihood of trying them in the future (Study 1). Participants indicated varied reasons for possibly trying each alternative form of alcohol use, but consistently perceived consequences for all forms (ie, health concerns), as …

Pseudoscorpions Of The Family Cheiridiidae (Arachnida: Pseudoscorpiones) Recovered From Burial Sediments At Pachacamac (500–1,500ce), Peru, Johnica J. Morrow, Livia Taylor, Lauren Peck, Christian Elowsky, Lawrence Stewart Owens, Peter Eeckout, Karl Reinhard

Karl Reinhard Publications

Fragmented remains of pseudoscorpions belonging to the family Cheiridiidae (Arachnida, Pseudoscorpiones) were recovered from Ychsma polity (c. AD 1000–1475) burial sediments from Pachacamac, Peru. Sediments from 21 burials were examined following rehydration in 0.5% trisodium phosphate for 48 h and subsequent screening through a 250 lm mesh. Materials larger than 250 lm were surveyed for the presence of arthropods. A total of two samples contained pseudoscorpion fragments, which were collected and quantified to determine the minimal number of pseudoscorpions present per gram of each sample. Following quantification, pseudoscorpion specimens were imaged utilizing confocal laser scanning microscopy (CLSM) to assist with …

Lead Content Of Lip Balms: A Cross Sectional Convenience Sample With Exposure Assessment Estimating An Average Daily Intake For Young Children, Julie Grunklee

Dissertations and Theses @ UNI

Lead remains one of the largest environmental toxins affecting children today (Costa, et al., 2004). It is associated with lower IQ, learning difficulties, decreased economic potential and other negative health effects and social behaviors (Kordas et al., 2006). In the United States (U.S.), high amounts of lead remain in and immediately around housing built before 1978 (Tarragó, 2015) as well as a variety of other sources, including cosmetics such as lip balms, that are marketed to the most lead-vulnerable population: young children. Lip balm was found to be the source a lead poisoned child in Minnesota (Minnesota resident, 28 years …

Poison In Pink, Sydney V. Cook

Graduate Student Theses, Dissertations, & Professional Papers

Humans slather, spray, mist, and cleanse their bodies with personal care products like lotion, hairspray, cologne, and shampoo every day. Our cupboards are stocked full of them, but few of us understand what is in those jars and bottles. We trust that if it’s on the shelf at the store, it’s safe. However, this is not always the case, and many personal care products contain chemicals that are harmful to human and environmental health.

My multi-disciplinary Environmental Studies thesis project combines evidenced-based research, interviews, nonfiction narrative, and science communication to create part of a book manuscript intended to educate general …
