dc.description.abstractFreshwater sources are subject to contamination of toxic compounds and other harmful materials through improper sewage cleanup and pollution. Ethinyl estradiol, a synthetic, steroidal estrogen used as contraception, is present in varying concentrations across freshwater sources worldwide. The objective of this study is to observe the sublethal effects and bioaccumulation of ethinyl estradiol (EE) in Lumbriculus variegatus. Data on the reproduction rate and segment regrowth of L. variegatusare currently being collected. In the future, bioaccumulation of EE within L. variegatuswill be observed through sediment tests and an ethinyl estradiol ELISA. Preceding data has found that ethinyl estradiol exposure leads to an increase in mortality, a decrease in offspring, and changes in reproductive morphology among other freshwater invertebrates. The data collected from this experiment would contribute to information available on the effects of low-dosage endocrine disruptor concentrations on freshwater organisms. The effects of EE and its bioaccumulation could be extrapolated to include bioaccumulation of EE in organisms of higher trophic levels, including vertebrates.
