Abstract

Abstract: Dechlorane Plus (DP) is a flame retardant used as a substitute of Mirex since 1970s, but it was not detected in the environment until 2006. Since then, this compound and its main relatives, Dechlorane 602, 603 and 604, have been mainly studied in environmental matrices for monitoring purposes, but the dietary exposure to them has been hardly investigated so far. In the present study, we determined this family of compounds in fish and vegetable oil samples from Catalonia (Spain), most of them used as health supplements. Determination was carried out by gas chromatography-high resolution mass spectrometry (GC-HRMS), after a clean up in a multilayer silica column and preparative high performance liquid chromatography (HPLC) equipped with a pyrenyl(ethyl) column. Concentrations of Dechlorane compounds were between below the limit of detection and 384.2 pg g −1 . Although there are only few studies about the presence of these pollutants in food or feed, concentrations obtained indicated that these compounds are in the same order in fish and vegetable oil health supplements as the few other food and feed studies. Graphical abstract: Highlights: Dechlorane Plus and dechlorane 602, 603 and 604 were studied in health supplements from Catalonia (Spain). Clean up was performed with a multilayer silica column and a preparative HPLC-PYE. GC-HRMS with electron impact and a three function acquisition method was used. Concentration of dechloranes in health supplements were between <LOD and 384 pg g −1 .
