摘要:	摘要： •An MSPD method was developed to extract Dechloranes from fish for the first time.•Factors affecting the efficiency of MSPD were optimised by a Box–Behnken design.•Limits of quantitation ranged from 9 to 15pg/g lipid weight.•Dec 602, Dec 603 and Dec 604 were detected in marketed fish for the first time.•MSPD is a low cost, effective method, and no dedicated instrumentation required. A method for the determination of chlorinated flame retardants: Dechlorane Plus, Dechlorane (Dec) 602, Dec 603 and Dec 604, in marketed fish is described. The method involves the use of matrix solid-phase dispersion (MSPD) prior to their determination by gas chromatography–electron-capture negative-ion chemical-ionisation mass spectrometry (GC–ECNICI-MS). Parameters that affect the extraction efficiency of the target analytes from fish samples were optimised using a Box–Behnken design method. MSPD integrated the extraction and clean-up procedures into a single step, which provides the benefits of being simple and convenient. The optimal extraction conditions involved dispersing a freeze-dried fish (1-g) in 2-g of silica gel, and packed with 1-g of Florisil, and then the target analytes were eluted with 20mL of n-hexane. The limits of quantification were 9–15pg/g-lipid weight. Preliminary results showed that the total concentrations of the target analytes ranged from 0.15 to 1.3ng/g-lipid weight. 其他題名： Food Chem 出版者： Kidlington: Elsevier Ltd 出版日期： 2014-12-01 出處： Food chemistry, 2014-12, Vol.164, p.286-292 版權： 2014 Elsevier Ltd 版權： 2015 INIST-CNRS 版權： Copyright © 2014 Elsevier Ltd.
