Sédiments contaminésIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : In the present paper analysis of alkylphenols and their short-chained ethoxylates was presented. The analytes were determined in sediments from Lake Malta as well as in water incoming to and outgoing from the lake. Sonication-assisted extraction was used for isolation of the analytes from the sediment samples. Solid-phase extraction with polytetrafluoroethylene sorbent was used for both clean-up of extracts and isolation of analytes from the water samples. Alkylphenols and their ethoxylates were quantitatively analysed with the use of HPLC with fluorescence detection. The analytes were determined in the sediment samples at relatively low concentrations with the maximum concentration of 168 μg kg–1 for nonylphenol monoethoxylate, which can be ascribed to periodic removal of sediments from Lake Malta. Maximum concentration in water samples was noted for nonylphenol at 0.56 μg L–1. No octylphenol nor its ethoxylates were found in the water samples.

Surfactants -- ToxicologieIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : There is a general paucity of literature data dealing with surfactants monitoring in sediments using specific methodologies. The only surfactants for which a consistent data set already exists are Linear Alkylbenzene Sulphonate (LAS) and Nonyl Phenol Ethoxylate (NPE). Concentrations of LAS and NPE, have in fact been monitored in both fresh water and marine sediments and were generally found to range from 0 to 5.0 mg/kg. Higher levels were reported only for some sediments collected close to untreated or inadequately treated sewage effluent discharges. This paper reviews the existing monitoring data for these surfactants in sediments and also reports the preliminary results of a recent monitoring programme carried out on the bottom sediments of the main watercourse in Italy, the river Po, using HPLC methodologies. For the first time, attention has been focused not only on LAS but also on Alcohol Ethoxylate (AE). To our knowledge this is the first example of a concentration-specific estimate of AE in sediments. These results will be discussed and compared with the limited toxicity information which is available on benthic organisms.
