    Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water by planar solid phase extraction – planar yeast estrogen screen (pSPE-pYES).
