Forensic Toxicology Essay

1. What argon the terce argonas cover by forensic toxicology?Toxicology covers post-mortem dose test, study medicate testing and investigatings into contraband materials.2. differentiate six specimen types that are oftentimes tested in forensic toxicology. down the stairs what circumstances is each specimen best-loved? Blood When testing for DUIs, and two samples for each death case. Urine Preemployment dose testing and is preferred over stemma as its eacsy to collect large amounts. Bile and colorful fluid Useful for adverting certain types of doses hairs-breadth Preemployment testing and is advantageous for looking and back in time literal fluid Provides the same benefits of urine without onslaught of privacy Breath Used for preliminary exam test on highways3. seduce the NIDA 5. bootlick a table showing the pursuance characteristics of each medicate structure of a representative molecule, drug group, symptoms of drug and drug source. National Institute on do drugs Ab enforce 5 cites the following drugs 4. Name several groups of medicinal drugs often conglomerate in fatalities. What characteristics render a drug some likely to be associated with overdose deaths? Sedative hynotics, cardio ready agents, antipsychotic agents, antiepileptic drugs and antidepressants. elude use, or organ damage confidential information to failure of metabolism.5. A 210-pound male consumes trio highballs each of which was made with 2 ounces of 80 proof whiskey. What is the expected peak in his lineage alcohol concentration? His blood alcohol concentration would raise by less than 0.06% as he is large than an average male.6. Name three modes for drug screening describe the advantages and disadvantages of each.NameAdvantagesDisadvantagesImmunoassays high gear sensitivityNot 100% particularThin Layer ChromatographyCan recognize hundreds of compounds in whizz run and is dirt cheapLabour intensive and highly technical foulUltraviolet-Visible Spec trophotometryReliable compound recognitionCannot identify less specific features7. Contrast gasconade chromatography with and without a smoke spectrometer detector. withdraw the advantages of the latter technology. Gas chromatography without a mass spectrometer detector relies solely on property time however the use of a mass spectrometer detector allows for all comp angiotensin converting enzyments of a mixture to be separated. The advantages of mass spectrometer detectors are that its often highly unique and provides a fingerprint of the molecule and on that pointfore one base use both the retention time and unique mass spectrum in order to identify substances.8. What are three methods of metal abridgment? Which is the optimal method and why? Three of the methods of metal analysis are colormetric assays, Atomic Absorption Spectrophotometry and neutron activating analysis however inductively coupled plasma-mass spectrum analysis is the optimal method as it is the most moder n and of very high quality.9. force the process of interpreting drug results in the context of preeemployment drug testing. Why is drug testing for employed individuals more than punishing? Preemployment drugs test usually use the person in questions urine, results are interpreted by comparing the take aim measured to an acceptable baseline. These baselines are not set at 0 be go however second hand exposure provide lead to trace amounts being metabolised and shown in the urine. Drug testing employed individuals is more difficult as it is usually in the context of confirming that drug cry was the reason for erratic behaviour, this involves a blood test rather than urine, and further to this there is no agreed level of drug in a system that can be classed as a cause for behaviour.10. In a published case, an gray woman with cancer dies. Three fentanyl patches are found on her body. Discuss the investigation of her death with respect to fixingss that would be satisfying to the forensic toxicologist in arriving at the cause and manner of death. The patches would be collected as evidence and tested for how much of the active ingredience was still present in the patches and two post mortem blood tests would be taken, one from the heart and one from an extremity, potentially the sites that the patches were employ to would be examined or swabbed also. The main factor in establishing the cause of death would be blood test results.
