Detection of drugs of abuse and pharmaceuticals in drinking water
Hall, Sarah; Peng, Yan; Gautam, Lata (Conference)The focus of this study is to develop a suitable extraction and analytical method for the detection of drugs of abuse and pharmaceuticals in drinking water. This is in response to concerns that traditional and current water ... -
The detection of drugs of abuse and pharmaceuticals in drinking water using solid-phase extraction and liquid chromatography-mass spectrometry
Hall, Sarah; Yan, Peng; Gautam, Lata (Article)Pharmaceuticals and drugs of abuse including novel psychoactive substances (NPS) are emerging as newer contaminants in the aquatic environment. The presence of such pollutants has implications on the environment as well ... -
The development of a novel adsorbent for collecting ignitable liquid residues from a fire scene.
Hall, Sarah; Gautam, Lata; White, Garry (Article)Different ad-hoc materials are being used to recover ignitable liquid residues (ILRs) when direct sampling is difficult at a fire scene. Our investigations have shown that these are unable to recover all target compounds ... -
Drugs of abuse in drinking water - a review of current detection methods, occurrence, elimination, and health risks.
Hall, Sarah; Gautam, Lata; Peng, Yan (Article)This review focuses on the drugs of abuse in drinking water, as their presence is of increasing global concern and trace levels of these compounds have previously been detected. Even though these levels are not toxic with ... -
The effect of paint type on the development of latent fingermarks on walls
Dawkins, Jo; Gautam, Lata; Bandey, Helen; Armitage, Rachel; Ferguson, Leesa (Article)Despite recent advances in DNA technology, fingermark evidence remains a fundamental method of ascertaining an individual’s identity. Latent fingermarks are the commonest type of fingermark encountered at crime scenes. The ... -
Ignitable Liquid identification using household adsorbents
Hall, Sarah; White, Garry; Gautam, Lata (Conference)The standard practice for the separation and identification of ignitable liquids is well established in fire debris analysis. A recent study by The Netherlands Forensic Institute identified passive headspace adsorption as ... -
Improvements to sampling and instrumentation for fire debris analysis using Tenax TA® and ATD-GC-MS.
Hall, Sarah; White, Garry; Gautam, Lata (Conference)The standard practice for the separation and identification of ignitable liquids is well established in fire debris analysis. A recent study by The Netherlands Forensic Institute identified passive headspace adsorption as ... -
Merging Wildlife and Environmental Monitoring Approaches with Forensic Principles: Application of Unconventional and Non-Invasive Sampling in Eco-Pharmacovigilance
Hall, Sarah; Richards, Ngaio; Gautam, Lata; Scott, Karen; Harrison, Nancy; Dowling, Geraldine; Zorilla, Irene; Fajardo, Iñigo (Article)Pharmaceutical residues in the environment have the potential to harm wildlife. A population’s fragility or an animal’s secretive nature may preclude capture and the use of invasive/destructive sampling techniques that are ... -
A novel adsorbent for the recovery and positive identification of ignitable liquids using GC-MS-ATD
Hall, Sarah; White, Garry; Gautam, Lata (Conference)Through survey results and personal communication with Fire and Scene Investigators it has been reported that non-standard and various adsorbent methods are being used for the recovery of Ignitable Liquid Residues (ILRs) ... -
An optimised gas chromatographic – mass spectrometric method for the chemical characterisation of benzylpiperazine and 1-arypiperazine based drugs
Hall, Sarah; Kuleya, Chipo; Gautam, Lata; Cole, Michael (Article)This study presents a method for the simultaneous detection of piperazines and congenors in street samples of amphetamine type stimulants. The method is based on simple solvent extraction of the drugs from the samples ... -
The Synthesis, Analysis and Characterisation of Piperazine Based Drugs
Hall, Sarah; Kuleya, Chipo; Gautam, Lata; Emmett, Trevor; Vaughan, Beverly (Conference)This study has investigated the syntheses and initial analytical profiling of phenylpiperazine drugs. This research aims to give an insight into the clandestine routes of synthesis and chemical profiles of 1-(4-fluorophe ...
