Postmortem Toxicology Of New Synthetic Opiods, Marta Concheiro, Rachel Chesser, Justine Pardi, Gail Cooper
Postmortem Toxicology Of New Synthetic Opiods, Marta Concheiro, Rachel Chesser, Justine Pardi, Gail Cooper

One hundred fifteen Americans die every day from opioid overdose. These overdose fatalities have been augmented by the increased availability of potent synthetic opioids, such as fentanyl and its derivatives. The death rate of synthetic opioids, other than methadone, increased by 72.2% from 2014 to 2015, and doubled from 2015 to 2016, situating the USA in the midst of an opioid overdose epidemic. The analytical identification of these opioids in postmortem samples and the correct toxicological data interpretation is critical to identify and implement preventive strategies. This article reviews the current knowledge of postmortem toxicology of synthetic opioids and the …

Regulation Of Radioactive Fracking Waste, Elizabeth Ann Glass Geltman, Nichole Leclair
Publications and Research
Natural gas extracted form shale reached record production totals in 2015 in the United States and the US Energy Information Administration (EIA) forecasts natural gas production will continue to increase. Wastes from shale gas extraction can contain the radioactive isotopes radium-226 (Ra-226) and radium-228 (Ra-228), which decay further into radon (Rn). Exposure to radon, a form of naturally occurring radioactive materials (NORM), is the leading cause of lung cancer in the United States, after smoking. This article explores how states handle the disposal of technologically enhanced naturally occurring radioactive materials (TENORM) and/or NORM waste from oil and gas operations to …
Stability Of Synthetic Cathinones In Oral Fluid Samples, Briana Miller, Jiyoung Kim, Marta Concheiro
Stability Of Synthetic Cathinones In Oral Fluid Samples, Briana Miller, Jiyoung Kim, Marta Concheiro
Publications and Research
Synthetic cathinones are new stimulant drugs derived from cathinone that have been sold as “legal highs” worldwide. These compounds can elicit powerful effects such as delusions, hallucinations as well as other potentially dangerous behavior. New analogs with varying effects and potencies are constantly introduced in the market to evade legislation, and they are not detected by routine screening and confirmation methods. Oral fluid is an alternative matrix of increasing interest in forensic toxicology. Its collection is non-invasive and easily supervised, and positive drug findings typically reflect recent drug exposure. The focus of this research was to develop a method for …
Bioanalysis For Cocaine, Opiates, Methadone And Amphetamines Exposure Detection During Pregnancy, Marta Concheiro, Elena Lendoiro, Ana De Castro, Eva Gonzalez-Colmenero, Ana Concheiro-Guisan, Patricia Penas-Silva, Manuel Macias-Cortina, Angelines Cruz-Landeira, Manuel Lopez-Rivadulla

Drug exposure during pregnancy constitutes a major legal issue and public health concern. Drug and metabolite determination in biological matrices from mother and newborn is an objective indication of prenatal drug exposure. However, limited data are available regarding the interpretation of these analytical results in terms of window of detection and degree of exposure. We collected paired maternal hair, meconium, placenta and umbilical cord from 727 mother-newborn dyads. We analyzed these specimens by liquid chromatography tandem mass spectrometry for the determination of cocaine, opioids, methadone and amphetamines, and compared the analytical results from the four different matrices. The cases were …

The presence of synthetic dyes is often underestimated in environmental protection. However, it has been demonstrated the impact of colored compounds in ecology and human health. Green tea (GT) and peppermint (PM) tea bag wastes were used as potential adsorbents of dyes from aqueous solutions to evaluate the effect of pH on the adsorption. Basic yellow 57, basic blue 99 and crystal violet were chosen as model dyes due to their widespread use in the industry. Dye solutions at different pH values were placed in contact with the adsorbents in batch experiments at room temperature. Results indicate that crystal violet …
Weaponizing Tear Gas: Bahrain’S Unprecedented Use Of Toxic Chemical Agents Against Civilians., Richard Sollom, Holly G. Atkinson
Weaponizing Tear Gas: Bahrain’S Unprecedented Use Of Toxic Chemical Agents Against Civilians., Richard Sollom, Holly G. Atkinson

The Bahraini government’s response to the early 2011 pro-democracy protests was brutal, systematic, and violent. In addition to birdshot and rubber bullets, government law enforcement attacked unarmed protestors with toxic chemical agents including tear gas. The government’s crackdown on the medical profession was especially harmful, as security forces arrested and detained doctors, raided health facilities, and obstructed patients from receiving necessary care. This report’s findings are based on field research that the authors conducted in Bahrain (April 2012) to investigate excessive use of force by law enforcement officials since June 2011—the end of Bahrain’s state of emergency. The medico-legal team …
