SPATIOTEMPORAL ENDOCRINE DISRUPTION ACTIVITY IN AN EFFLUENT-IMPACTED RIVER UNDER LOW INSTREAM FLOW: INTEGRATING FIELD AND LABORATORY ASSESSMENTS

Effluent-impacted waters represent a threat to aquatic organisms due to their potential to cause adverse biological effects, such as endocrine disruption. In the present study, field and laboratory experiments are integrated to evaluate estrogenicity of wastewater effluent to fish, during summer and fall seasons. Juvenile rainbow trout (Oncorhynchus mykiss) were individually placed in cages and exposed for 1, 3 and 7 days, at three different locations downstream and one location upstream of a wastewater treatment plant (WWTP) in East Canyon Creek, Utah, a river influenced by seasonal snowmelt. In the summer, concentrations of plasma vitellogenin (VTG) were high in the upstream and furthest downstream sites on day 7. Estradiol (E2) concentrations were high on day 7, across all sites. In the fall, slight increases of VTG were observed at the site closest to the WWTP, whereas high levels of E2 were observed on day 7 at the two downstream sites near the WWTP, though E2 concentrations were lower compared to the summer. On-going assessments aim to estimate endocrine disruption in vitro by exposing primary hepatocytes to water extracts from samples collected at the same locations where the fish were deployed.
