ISO 19040-1:2018 is an international standard for determining the estrogenic potential of water and wastewater. It specifically uses a yeast estrogen screen, a reporter gene assay that activates the human estrogen receptor alpha, to identify substances with estrogen-like activity. The standard is applicable to various water types including fresh water, wastewater, and extracts from sediments, and can be used to analyze single substances or chemical mixtures.
