The development of appropriate methods for drug analysis at the Forensic Chemistry Laboratory, Cape Town
The Forensic Chemistry Laboratory, Cape Town, analyses samples submitted by forensic pathologists in order to assist with determining the cause of death in cases of unnatural death. Many of these samples test positive for the presence of drugs and other toxic substances. Because of resource …

Investigating the role of commonly misused drugs in suspected unnatural and/or unexplained deaths in Cape Town in 2022
… determining the cause of death. In 2022, the Forensic Toxicology Unit within the Western Cape Forensic Pathology Service piloted a targeted drugs analysis at Salt River Mortuary in Cape Town. This permitted an assessment of commonly misused drugs in suspected unnatural and/or unexplained …

Non-destructive analysis of popular cigarette brands utilizing attenuated total reflectance (ATR) and diffuse reflectance infrared fourier transform spectroscopy (DRIFTS) and chemometrics
… DNA analysis may be the first method used for forensic analysis. However, other methods of analysis, such as analysis of the various components that make up a cigarette, may also be useful. Cigarette butts are comprised of a filter that is enclosed in an outer wrapping paper that is inserted …

Assessment of the suitability of blood samples collected for toxicological analysis for subsequent genetic analysis: A follow-up study one year later
… to the rest of the country. The provincial Forensic Pathology Service may encounter cases where drug-related fatalities are unclear whether death was accidental or suicidal, or drug toxicity is inconsistent with the medical/social history. This may be due to genetic alterations with drug …

New Developments in Analytical Toxicology for the Investigation of Drug Facilitated Crime
… victim is one of the most challenging facets of forensic chemistry. Drug concentrations can be very low, as often only a single dose is administered, and the pharmacodynamics of commonly employed drugs further hinders the testing process.<br/><br/>The research presented in this work shows the …

Assessment of the suitability of blood samples collected for toxicology for subsequent genetic analysis: A follow-up study after five years
… testing is however not routinely conducted in forensic mortuaries, and historic backlogs within the National Forensic Chemistry Laboratories may delay the processing of toxicology samples by months or even years. As such, specimens that have undergone toxicological testing and were stored …

Analysis of the volatile organic compounds produced by the decomposition of pig carcasses and human remains
Complex processes of decomposition produce a variety of chemicals as soft tissues and their component parts are degraded. Among others, these decomposition by-products include volatile organic compounds (VOCs) responsible for the odour of decomposition. Human remains detection (HRD) canines utilize …

Assessment And In Vitro Repair Of Damaged Dna Templates From Forensic Stains
… DNA templates. Remedies may be available to the forensic scientist to deal with LCN templates and soluble inhibitors but none presently exist for damaged DNA. In fact, only recently has the biochemical nature, the extent of DNA damage in physiological stains and the point at which the damage …
