ABSTRACT: Monitoring the levels of organic contaminants (OCs) in local freshwater systems is essential for sustaining healthy ecosystems and communities. OCs found in freshwater systems are suspected of disrupting normal biological pathways and mimicking endocrine disruptor compounds. . The purpose of this study is to analyze OC samples from eight streams located in Durham, North Carolina. Preliminary gas chromatography-mass spectrometry results suggest that OCs are present in these streams. OCs detected includes phenol, 2, 4-bis (1,1-dimethylethyl), the antioxidant used for cosmetic formulations known as butylated hydroxytoluene (BHT), and Astaxanthin. Several detected OCs contain phenolic and methyl substituent groups, which are essential for binding estrogen receptors. Findings suggest the need to further study the effects OC’s may have on gene expression.
