Hair ethyl glucuronide (hEtG) is a marker used for previous alcohol consumption. Correlations have been reported between the amount of alcohol consumed and hEtG concentration, but little has been published regarding relatively low levels of alcohol consumption and associated hEtG concentrations close to the limit of quantification (LOQ). Here, we investigate hEtG concentrations in non-excessive (<......  hiện toàn bộ
 Recent progress in the chemical attribution of chemical warfare agents and highly toxic organophosphorus pesticidesSpringer Science and Business Media LLC -  Tập 39  - Trang 334-349 - 2021
Xiaogang Lu, Zixuan Zhang, Runli Gao, Hongmei Wang, Junhua Xiao
This paper reviews the background of the development of chemical attribution technology, and discusses analytical and chemometrics technologies for chemical warfare agents (CWAs) and highly toxic organophosphorus pesticides. The analytical methods include gas chromatography–mass spectrometry (GC–MS), liquid chromatography–mass spectrometry (LC–MS), infrared spectroscopy (IR), Raman spectroscopy, n......  hiện toàn bộ
 VOCs as fingerprints for the chemical profiling of hashish samples analyzed by HS-SPME/GC–MS and multivariate statistical toolsSpringer Science and Business Media LLC -  Tập 36  - Trang 243-260 - 2017

The statistical evaluation of the chemical profile of seized hashish samples is a valuable tool to aid the estimation of the route through which the material has reached the dealers’ market. In this study, the complete volatile organic compound (VOC) emission profiles of 48 seized hashish samples have been analyzed by means of headspace solid-phase microextraction/gas chromatography–mass spectrome......  hiện toàn bộ
 Effects of aromatic ring-substituted phenethylamines on the release of dopamine and serotoninSpringer Science and Business Media LLC -  Tập 37  - Trang 104-112 - 2018

Significant disturbances of the classical amphetamines on the dopamine (DA) and serotonin (5-HT) systems have been previously reported. However, few studies have been conducted on the effects of new psychoactive phenethylamines on the release of DA and 5-HT. In the present study, the effects of new psychoactive phenethylamines with a variety of aromatic ring substitutions (5-API, 3-FMA, 5-MAPB, an......  hiện toàn bộ
 Heroin poisoning deaths with 6-acetylmorphine in blood: demographics of the victims, previous drug-related offences, polydrug use, and free morphine concentrations in femoral bloodSpringer Science and Business Media LLC -  Tập 30  - Trang 19-24 - 2011
Alan Wayne Jones, Anita Holmgren, Johan Ahlner
This article discusses cases of drug-poisoning death in which 6-acetylmorphine (6-AM) was identified in blood as evidence for recent use of heroin. We report the demographics of the victims, previous drug-related offences, polydrug use, and the concentrations of free morphine in peripheral blood. After solid-phase extraction, morphine, codeine, and 6-AM were determined in blood samples by isotope-......  hiện toàn bộ
 Organ distribution of 4-MEC, MDPV, methoxetamine and α-PVP: comparison of QuEChERS and SPESpringer Science and Business Media LLC -  Tập 36  - Trang 320-333 - 2018
Sabrina Lehmann, Bastian Schulze, Andreas Thomas, Thomas Kamphausen, Mario Thevis, Markus A. Rothschild, Katja Mercer-Chalmers-Bender
An organ distribution investigation was carried out on two deceased (A and B) who consumed 4-methylethcathinone (4-MEC), methylenedioxypyrovalerone (MDPV), methoxetamine (MXE) and α-pyrrolidinopentiophenone (α-PVP). The detection of the aforementioned drugs in the specimens was performed on a liquid chromatography–tandem mass spectrometry system. Two different extraction methods were compared with......  hiện toàn bộ
