A 10 lL aliquot was determined by gas chromatography with chemical ionisation mass spectrometry (GC–CI-MS) using the selected-ion-storage (SIS) mode. The limits of quantitation (LOQs) were 0.03–0.36 ng/g. Preliminary results revealed that NDMA was present in the highest concentration‚ ranging from 0.8 to 3.2 ng/g. Ó 2012 Elsevier Ltd.
