This document specifies a method for the determination of the estrogenic potential of water and waste water by means of a reporter gene assay with genetically modified yeast strains Saccharomyces cerevisiae. 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 substances or of chemical mixtures; drinking water.
