Complete suicides and parasuicides are a major cause of death and disability in South Africa and the rest of the world. The epidemiology, pathology and toxicology of complete suicides were investigated in this study. All the complete suicide cases, which were presented to Salt River Medicolegal Laboratory over a period of one year (1 January 1997 - 31 December 1997), were analysed. The candidate personally conducted 148 of the alleged 180 suicide cases that presented in this time period (82%). The candidate did all the follow up investigations herself.

Abstract:

The forensic toxicologist faces challenges in the detection of drugs and poisons in biological samples due to transformations which occur both during life and after death. For example, changes can result from drug metabolism during life or from the use of formalin solution for post mortem embalming purposes. The former requires the identification of drug metabolites and the latter the identification of chemical reaction products in order to know which substances had been administered. The work described in this thesis was aimed at providing ways of tackling these challenges and was divided int

Abstract:

New designer drugs are constantly emerging onto the illicit drug market and it is often difficult to validate and maintain comprehensive analytical methods for accurate detection of these compounds. Generally, toxicology laboratories utilize a screening method, such as immunoassay, for the presumptive identification of drugs of abuse. When a positive result occurs, confirmatory methods, such as gas chromatography (GC) or liquid chromatography (LC) coupled with mass spectrometry (MS), are required for more sensitive and specific analyses. In recent years, the need to study the activities of the

Abstract:

Bio-analytical results are influenced by in vivo factors such as genetics, pharmacological and physiological conditions and in vitro factors such as specimen composition, sample additives and storage conditions. Zopiclone (ZOP) is a short-acting hypnotic drug (Imovane®) used for treatment of insomnia. ZOP is metabolized by three major pathways; oxidation to the active zopiclone N-oxide (ZOPNO), demethylation to the inactive N-desmethylzopiclone (NDZOP) and oxidative decarboxylation to other inactive metabolites. ZOP is increasingly being encountered in forensic cases and is a common finding in

This thesis examines the use of nail as an alternative biological specimen in forensic toxicology. Nail is a difficult analytical matrix from which to extract drugs because of its tough physical composition, based on keratin.

Grinding at liquid nitrogen temperatures was found to be an effective procedure and the conditions were optimised to a two or three cycle programme of freezing and grinding. Small particle sizes were obtained of approximate size 1µm. It was established that drugs

Abstract:

A intoxicação intencional de animais e de pessoas é uma ameaça à saúde e à segurança públicas em todo o mundo. No Brasil, os pesticidas da classe dos carbamatos aldicarbe e carbofurano são facilmente obtidos, e uma única dose letal daqueles é facilmente misturada a alimentos palatáveis e iscas. Foram analisadas as necropsias de 26 gatos e 10 cães, da rotina do Serviço de Patologia Animal da FMVZ-USP, com variados intervalos post mortem e tipos de conservação de carcaça, intoxicados pelos carbamatos aldicarbe e carbofurano, confirmados pela cromatografia de camada delgada (CCD) e cromatografia

Abstract:

No presente trabalho, foram desenvolvidos e validados dois métodos com o objetivo de determinar os herbicidas paraquat e glifosato, bem como o AMPA, principal metabólito do glifosato, em amostras de maconha apreendidas pela polícia de Campinas, São Paulo. A detecção e quantificação de herbicidas na maconha são necessárias e importantes para alertar o real risco que a droga pode oferecer aos usuários. Existem várias razões que explicam a presença de herbicidas na maconha em vários países, incluindo o Brasil. A eletroforese capilar foi utilizada para determinação dos herbicidas. Um método de det

This concern rises from clinical episodes of psychotropic effects that go beyond the regular range of marijuana and THC – namely, panic attacks, psychosis, catatonia, addiction and withdrawal symptoms.

Abstract:

Drug profiling, isto é, a caracterização de amostras de drogas apreendidas no sentido de estabelecer conexões entre apreensões realizadas em diferentes épocas e/ou locais a uma origem comum de produção clandestina, tem sido um objetivo dos órgãos governamentais responsáveis pela prevenção/repressão. Especificamente tratando-se de comprimidos de ecstasy, o conhecimento de suas propriedades físicas e químicas é de relevante importância para discriminar a apreensão de diferentes lotes. Nesse contexto, o presente trabalho propõe uma nova abordagem para estabelecer conexões entre apreensões de comp

Abstract:

Drug facilitated assault (DFA) is an increasing problem in the UK. The crime often occurs through the surreptitious administration of a drug into a victims drink, rendering the victim unable to resist the assault. The detection of these drugs in a biological specimen from the 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. The research presented in this work shows the development of several new assays for

Abstract:

Novel psychoactive substances (NPS) represent a great challenge to toxicologists due to the ability of illicit drug manufacturers to alter NPS chemical structures quickly and with ease to circumvent legislation regulating their use. Each time a new structure is introduced, there is a possibility that it has not been previously recorded in law enforcement or scientific databases. Many toxicology laboratories use targeted analytical methods that rely on libraries of known compounds to identify drugs in samples. However, these libraries do not include large numbers of NPS which could result in no

Abstract:

The objective of this research was to examine whether the United States and Canada have successfully implemented their Great Lakes Water Quality Agreement and to identify the factors determining the continuation of any injury to human health from pollution of the boundary waters. The Agreement was first negotiated in 1972 as part of the legitimation of the social unrest of the 1960s and gave special responsibilities to the International Joint Commission to advise the Parties of problems of water quality. It has been subject to periodic review and occasional renegotiation and amendment. Specifi

Abstract:

Les intoxications ayant pour cause la prise de toxiques végétaux sont relativement fréquentes. Ces intoxications font suites à une ingestion accidentelle ou volontaire (aliments contaminés, préparations à but « thérapeutique », acte suicidaire, .). Le nombre de ces intoxications est sous-estimé car les signes cliniques sont souvent non spécifiques et les médecins méconnaissent la dangerosité des composés présents et l'incidence des intoxications par les plantes. La sous-estimation du nombre d'intoxications est également liée au manque de méthodes analytiques développées spécifiquement pour la
