Phthalate esters in freshwaters as markers of contamination sources—A site study in Italy

A sampling campaign for the determination of phthalate acid esters (PAEs) levels in freshwaters and sediments of rivers and lakes of the Rieti District (central Italy) was carried out in 1994. Sixty-six water samples, collected in three series, and thirteen sediment samples were analyzed by gas chro...

Description
Summary:A sampling campaign for the determination of phthalate acid esters (PAEs) levels in freshwaters and sediments of rivers and lakes of the Rieti District (central Italy) was carried out in 1994. Sixty-six water samples, collected in three series, and thirteen sediment samples were analyzed by gas chromatography/mass spectroscopy (GC/MS). The analytical results on water samples showed a direct relation of PAEs levels with the input of urban or industrial treated wastewaters near the sampling point. Because of their tendency to be adsorbed on sediments, the presence of PAEs was limited to within a few kilometers of the source of contamination. Accumulation factors in sediment samples, in fact, ranged from 10 to 100.
