The method is based on solid phase extraction (SPE) followed by analysis by liquid chromatography coupled with mass spectrometry (HPLC-ESI-MS/MS). A geographic variability of estrogens was assessed on a large scale of the Danube River and its main tributaries, Jiu, Olt and Arges; assessment of the degree of contamination of surface water from our country with these hormones.en-USEmerging micropollutantsEstrogensLiquid chromatographyWaterProject
