1Volatile dimethylsiloxanes in market seafood and freshwater fish from the Xúquer River, Spain.

Sanchís J1, Llorca M2, Picó Y3, Farré M4, Barceló D2.

Sci Total Environ. 2016 Mar 1;545-546:236-43. doi: 10.1016/j.scitotenv.2015.12.032. Epub 2015 Dec 31.

Volatile dimethylsiloxanes are a family of synthetic organosilicon-compounds, which have received rising attention because of their widespread use and occurrence in the environment. In the present work, an analytical method based on ultrasound-assisted solid-liquid extraction (USAE) followed by gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) has been optimized and applied to assess the presence of eight volatile dimethyl siloxanes (VMS) (hexamethylcyclotrisiloxane (D3), octamethylcyclotetra-siloxane (D4), decamethylcyclopentasiloxane (D5), dodecamethylcyclohexasiloxane (D6), octamethyltrisiloxane (MDM), decamethyltetrasiloxane (MD2M) and dodecamethylpentasiloxane (MD3M) and tetradecamethylhexasiloxane (MD4M)) in fish.
