Water quality. Determination of the estrogenic potential of water and waste water - In vitro human cell-based reporter gene assay1 Scope This document specifies a method for the determination of the estrogenic potential of water and waste water by means of a reporter gene assay utilizing stably transfected human cells. This reporter gene assay is based on the activation of the human estrogen receptor alpha. This method is applicable to: fresh water; waste water; aqueous extracts and leachates; eluates of sediments (fresh water); pore water; aqueous solutions of single
