Fragrance Materials (FMs) are omnipresent components of household and Personal Care Products (PCPs). In spite of their widespread use, little is known about their environmental occurrence. We selected 17 among the longest-last- ing and most stable fragrance ingredients that are commercially available, namely: Amberketal, Ambrofix, Amyl Sa- licylate, Benzyl Salicylate, Bourgeonal, Dupical, Hexyl Salicylate, Isobutavan, Lemonile, Mefranal, Myraldene, Okoumal, Oranger Crystals, Pelargene, Peonile, Tridecene-2-Nitrile, Ultravanil. A new analytical method was devel- oped to quantify FMs in water samples and it was applied to perform the first study about the distribution of these compounds in the surface waters of the city of Venice and its lagoon. Total FMs concentrations range from about 30 ng L− 1 to more than 10 μg L− 1 in polluted canals during the low tide. Sewage discharges were supposed to be the main sources of the selected FMs in the environment. Salicylates, oestrogenic and allergenic compounds, were in general the most abundant and widespread components. This study reports for the first time the detection of most of the selected FMs in surface waters and represent the first step to understand their environmental fate.
I materiali profumati (FM) sono componenti onnipresenti dei prodotti per la cura della casa e della persona (PCP). Nonostante il loro uso diffuso, si sa poco della loro presenza ambientale. Abbiamo selezionato 17 fra le fragranze più durature e stabili disponibili in commercio, vale a dire: Amberketal, Ambrofix, Amyl Salicylate, Benzyl Salicylate, Bourgeonal, Dupical, Hexyl Salicylate, Isobutavan, Lemonile, Mefranal, Myraldene, Okoumal , Cristalli di Oranger, Pelargene, Peonile, Tridecene-2-Nitrile, Ultravanil. È stato sviluppato un nuovo metodo analitico per quantificare le FM nei campioni d'acqua ed è stato applicato per eseguire il primo studio sulla distribuzione di questi composti nelle acque superficiali della città di Venezia e della sua laguna. Le concentrazioni totali di FM variano da circa 30 ng\L a più di 10 μg\L nei canali inquinati durante la bassa marea. Gli scarichi fognari avrebbero dovuto essere le principali fonti dei FM selezionati nell'ambiente. I salicilati, composti estrogenici e allergenici, erano in generale i componenti più abbondanti e diffusi. Questo studio riporta per la prima volta il rilevamento della maggior parte dei FM selezionati nelle acque superficiali e rappresenta il primo passo per comprenderne il destino ambientale.

Abstract
Fragrance Materials (FMs) are omnipresent components of household and Personal Care Products (PCPs). In spite of their widespread use, little is known about their environmental occurrence. We selected 17 among the longest-last- ing and most stable fragrance ingredients that are commercially available, namely: Amberketal, Ambrofix, Amyl Sa- licylate, Benzyl Salicylate, Bourgeonal, Dupical, Hexyl Salicylate, Isobutavan, Lemonile, Mefranal, Myraldene, Okoumal, Oranger Crystals, Pelargene, Peonile, Tridecene-2-Nitrile, Ultravanil. A new analytical method was devel- oped to quantify FMs in water samples and it was applied to perform the first study about the distribution of these compounds in the surface waters of the city of Venice and its lagoon. Total FMs concentrations range from about 30 ng L− 1 to more than 10 μg L− 1 in polluted canals during the low tide. Sewage discharges were supposed to be the main sources of the selected FMs in the environment. Salicylates, oestrogenic and allergenic compounds, were in general the most abundant and widespread components. This study reports for the first time the detection of most of the selected FMs in surface waters and represent the first step to understand their environmental fate.File | Dimensione | Formato | |
