BEHAVIOR OF ANIONIC AND NONIONIC SURFACTANTS AND THEIR PERSISTENT METABOLITES IN VENICE LAGOON, ITALY

摘要

The occurrence and behavior of aromatic surfactants linear aklylbenzene sulphonates(LAS)and nonylphenol po- lyethoxylates(NPE)as well as their biotransformatio products in central lagoon of Venice, Italy, were investigated by monitoring deep-and shallow-water lagoon stations, two riverine sites, and one sea station. Additions samplings were conducted at the three inlets connecting the lagoon with the open sea under both ebb and low-tide conditions, and a radiometrically dated sediment core spanning the last century was examined.
