Aromatic surfactants and metabolites in wastewaters, sludges, ambient waters and sediments

Aromatic surfactants are chemicals of high environmental concern. It was shown that nonionic surfactants of the nonylphenol polyethoxylate type have a rather complex metabolic pattern characterised by formation of persistent metabolites, which are more toxic to the aquatic life than the parent compounds. The analytical determination of these ecotoxic metabolites requires a very sophisticated analytical approach based on high resolution chromatographic techniques and highly specific detection.
