Polyethoxylated C12–C15 alcohols, nonylphenols and ((nonylphenoxy) polyethoxy)acetic acid and their brominated derivatives were identified in the River Llobregat and in the tap water of Barcelona by GC/MS and FAB mass spectrometry. Whereas GC/MS is limited to those compounds with a low polyethoxylation degree, FAB mass spectrometry is a fast and simple technique to determine sufactants with a high range of oligomers present in the samples. We believe that both techniques are complementary. The source of these compounds are the dumps of surfactant industries and dyeing and textile processes. Their brominated derivatives are formed in the chlorination stages in the water works plant due to a high content of bromide ions in the upper course of the river.
