Forensic chemistry is a branch of chemistry that applies the techniques and concepts of chemistry to provide evidence and testify in court. Some federal agencies such as FDA (Food and Drug Administration) and National Institute of Justice use forensic chemistry experts to investigate the crimes committed against the society, which include environmental pollution, food adulteration, and distribution of unsafe chemical substances. In the United States, cocaine and other illegal drugs can put society at risks. Thus, experts in forensic chemistry uses different processes to perform a laboratory test to identify the presence of substances. A chemical analysis carried out in the laboratory can help to detect illegal drugs, which will assist the police or other law enforcement agents to prosecute offenders in the law courts. (Drug Enforcement Administration 1).
Moreover, the forensic chemistry analyzes non-biological materials to detect a trace of evidence from the crime scenes to found unknown material to be used as evidence. A forensic chemistry focuses on laboratory tests on samples that investigators have collected. Forensic chemistry specialists use a variety of techniques to analyze and identify evidence. They use techniques such as microscopy, X-ray, infrared, UV, optical analysis and other technologies. The specialist is required to document their findings as well as writing a report to support their investigation. Sometimes, forensic chemists may be called upon in the courts to testify.
Thus, a field of forensic chemistry uses the confirmatory tests on suspected or seized materials, and the results of the analysis will be presented in court to prosecute the criminals. Thus, the amount of illegal substance discovered in the substances will be presented in the court which will determine the level of sentencing to be levied for a convicted offender. An individual who completes a field of forensic chemistry will be qualified to work in different modern laboratories at federal, state, regional and local levels. Moreover, a graduate of forensic chemistry will also be able to secure employment in pharmaceutical companies, chemical companies, and different federal agencies such Environmental Protection Agency, Food and Drug Administration and Drug Enforcement Administration. Despite assisting in a crime investigation, an expert in forensic chemistry does not normally present in the crime scenes, rather, they work in the laboratory to analyze and identify the evidence that can be used in the court.
Since forensic chemists work in a laboratory setting,...
Forensic analysis has also been used successfully in many paternity cases. Furthermore, the advantages of Forensic DNA technology are extensive and have been employed in forensic fields such as the detection of bacteria and various other pollutants in water and in the matching of recipients in organ donor programs. It should also be noted that forensics is a field that covers many areas and fields of knowledge and which can
Therefore, the ability to determine facts in a case from very small particles of matter has proven to be of invaluable assistance in criminal investigation and procedure; for example, forensic analysis has been used successfully in many paternity cases. 3. Myths and realities There many misconceptions surrounding forensic science and especially CSI or Crime Scene Investigation. This is mainly due to the way that CSI has been portrayed in film and
But if there five or ten, along with other forensic evidence, it is enough to say that an individual committed a crime "beyond a reasonable doubt." The glove that didn't fit O.J. Simpson at his trial for the murder of his wife and another man is an example of forensic evidence that cleared someone who was falsely accused. Whether that was the correct verdict, we will never know for certain.
Essay Topic Examples 1. The Evolution and Impact of DNA Analysis in Forensic Science This essay will explore the revolutionary introduction of DNA analysis in forensic investigations. It will trace the origins of DNA fingerprinting, delve into the technical advancements that have made DNA evidence a linchpin in legal outcomes, and discuss the societal and ethical implications of such powerful technology. This topic will also highlight the role of DNA analysis in
Criminal investigation plays a crucial role in law enforcement in relation to the arrest, prosecution, and conviction of criminals. This paper examines the evolution of criminal investigation research in light of the developments that have taken place in this field. A history of the criminal investigation is also discussed as well as a definition of the criminal investigation process. The author also examines how DNA, fingerprinting, and forensic science have
Science of Forensic Toxicology Prior to modern medicine and the advent of forensic toxicological sciences, death from intentional poisoning was often indistinguishable from natural causes. Consequently, poisoning with toxic substances was a preferred form of murder throughout human history until relatively recently. Arsenic, in particular, was used so often as a method of murdering wealthy elderly relatives, that it was sometimes known as "inheritance powder." Prior to the nineteenth century, it was virtually
