This document specifies a method for the determination of the thyroid activity of water and waste water by means of a reporter gene assay with genetically modified Xenopus laevis eleutheroembryos.
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 organism preparation methods (freeze-drying, extraction, mineralization) and quantification of the chemical substances do not fall within the scope of this document.
