  1. The Environmental Occurrence, Fate and Ecotoxicity of Prozac®, Zoloft®, Paxil®, Celexa® and Luvox® in Aquatic EnvironmentsMarsha C. Black, Departmentof Environmental Health Science, University of Georgia, Athens, GA • The Environmental Issue • Heavy use of human prescription and over the counter drugs • SSRI antidepressants are widely prescribed • Prozac®, Zoloft®, Paxil®, Celexa®, Luvox® • Among the 200 most prescribed drugs • www.Rxlist.com • Drugs and metabolites are excreted by humans • Enter sewers or septic tanks for treatment • Wastewater treatment may not degrade • May be released to aquatic environment • Could SSRIs cause adverse effects in the aquatic environment? • The Proposed Research • Characterize degradation, fate of these drugs in the aquatic environment • Measure acute and chronic impacts on aquatic organisms • Invertebrates (water flea), mosquito fish, frogs • Toxicity Results • Prozac has toxic effects in long-term exposures • Delayed development in fish • Altered behavior in fish and frogs • Delayed metamorphosis in frogs • Limb malformations in frogs • Effects were measured at 0.6-100X the concentrations measured in streams • Impact of EPA-Sponsored Research • SSRIs have potential to impact aquatic organisms • Need for effective removal of SSRIs and other drugs by wastewater treatment plants (WWTP) • Future regulatory action may be warranted •  Cooperating Scientists University of Georgia Mississippi State Chemical Lab Ted Henry Kevin Armbrust Emily Rogers Jeong Wook-Kwon Ben Hale
