| Resumen: | 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. The limit of quantification (LOQ) of this method for the direct analysis of water samples is between 8 ng/l and 15 ng/l 17 |
