Screening for Estrogen Active Nonylphenols in Water by Planar Solid Phase Extraction – Planar Yeast Estrogen Screen

Nonylphenols (NP) are common substances that have been detected in highly diverse foodstuff and that inter alia show estrogenic activity resulting in the EU classification of priority hazardous substances. The high environmental health risk from NP makes the determination of their total concentration critical.

A highly selective and innovative approach to detection of estrogen active compounds (EAC) is described that combines planar solid phase extraction (pSPE) and planar yeast estrogen screen (pYES).
