From: Efficiency of advanced wastewater treatment technologies for the reduction of hormonal activity in effluents and connected surface water bodies by means of vitellogenin analyses in rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta f. fario)

a Absorbance measured in homogenates of juvenile brown trout exposed for 99 days post-fertilization at the bypass stations in 2014; means and SD are shown. All samples were analyzed within one semi-quantitative vitellogenin salmonid (Salmoniformes) biomarker ELISA kit (enzyme activity = color intensity is proportional to the concentration of vitellogenin in the sample). Each treatment n = 12. No significant differences with the Steel–Dwass test; p > 0.05. For better comparison, previous results from 2013 prior to the upgrade are also shown. These results were already published in PlosOne by Henneberg et al. 2014 [22]. b Values of a relative to negative control. Neg. control was set to 100 %
