FA enrichment was carried out from rat plasma by n-BuCl extraction; quantitation with nitrogen phosphorus detection (NPD) [30] provided Blood [13,17,20,30,34,35,37,38,40,47,49,55,56,63,66,69,74] Hair [15,19,[43][44][45][46][47]54,57,75,77,78,80] Saliva [23,24,28,52,55,56,58,68,71] Environmental water's illicit pollutatnts [41,42,61,65] Seizure [18,26,32] Kidney [59,62,74] Miscellaneous Urine [16,19,[20][21][22]25,[27][28][29]33,36,[47][48][49][50]53,55,56,64,67,72,74,76] Standard [31,79] Liver [62,74] Nail [39] Breath [14] Placenta [60] Skin [70] Tooth [51] Muscle [74] In two approaches [31,32], the authors omit enrichment step. The GC-combustion-isotope ratio mass spectrometry (GC-C-IRMS) method was designed and successfully used in the discrimination of GBL seizures, based on their 12 C/ 13 C ratio contents: suitable characteristics to identify the producer, the applied chemicals and the broad diversity of synthesis pathways [31]. ...
