Forensic toxicology is a branch of forensic science concerned with the study of toxic substances or poisons; toxicology is the study of the toxic or harmful effects of chemicals. It is concerned with how toxins act, when their harmful effects occur, and what the symptoms and treatments are for poisoning. It also involves the identification of the substances involved (Interdisciplinary).
Forensic toxicologists have faced numerous challenges throughout the 1800’s and are still facing some of these challenges today. In Gettler’s and Norris’s time of being head of forensics in New York, they faced problems within toxicology study, and some out of toxicology. One of their main problems was metabolizing a poison and determining the lethal dose.
Metabolizing of a poison was an early problem for Norris and Gettler, especially when working with cyanide, one of the many poisons they analyzed. When inhaled,

Forensic toxicologists employ a large number of analytical techniques to determine the drugs or poisons relevant to an investigation; the capacity of a laboratory to conduct routine toxicological analysis varies depending upon equipment, technical capability and analyst experience. When needed, there are specialty toxicology labs that can test for almost any potential toxin or metabolite in almost every kind of post-mortem sample. A laboratory should be accredited to perform the analytical work and must be subject to regular inspections. This will ensure that laboratories can reproduce accurate and reliable results for investigations. All laboratory tests conform to standard operating procedures, results are confirmed to meet standards, and reported results are peer reviewed by a second toxicologist before being released. Even so, we still use methods that Gettler used in his
Most medical experts often had to supplement their findings with more conventional detective work. Rob Rapley recounts the famous cases of the day including the factory workers who painted glow in the dark watch dials with radium paint. Women who worked in these factories were unknowingly being poisoned as they put their brushes in their mouths to touch up the point. Since women were dying years after having access to the paint, it was hard to tell whether or not they died from the paint at work or from another cause. It wasn’t until Gettler ran tests on a woman’s bones five years after her death and found radium still remaining in her bones. Also, a man named Mike Malloy miraculously survived tragic situations such as being run over by a taxi and being fed rotten food before finally dying from poisonous gas. The cause of his death, however, was not spontaneous and was a result of money hunger than those who insured him shared. This models that murderers used poison to commit crimes in search of money. One pair of murderers, exculpated by Gettler’s evidence in 1924, was finally caught in 1936, when they killed again using the same poison.
Forensic pathologists are the people who determine the cause and time of death if the deceased person died under suspicious circumstances, whether they be violent or not. They determine if the death was accidental, a homicide, natural, a suicide, or even if the cause of death was unknown. They do this by studying said victim’s medical history, evaluating the crime scene for evidence, studying the body for any clues, and performing an autopsy. After determining the cause, time, and the manner in which the victim died, forensic pathologists make a written report on the victim and sometimes testify in court to report their findings.
When a death occurs suddenly, unexpectedly and from unnatural or unknown causes, a forensic scientist has the duty to gather and analyze evidence to determine whether the victim died from a previously undiagnosed disease or infection or from a homicide, suicide or accident (Lurigio, 2009). When considering suicide as the probable cause of death, we are looking at the act of intentionally killing oneself through one’s own effort or with the assistance of another (Sever, 2009). The resolution of the manner of death by a forensic pathologist as suicide is based on a series of factors which eliminate natural causes of death, homicide and accident (Geberth, 2013, p.55). The cause of death is also determined by the medical examiner in conjunction with the crime scene investigator; however, it can only be determined after a thorough investigation is concluded. Therefore, in the complicated process of doing a death investigation there are several mistakes that should be avoided, which are discussed in Geberth’s article, Seven Mistakes in Suicide Investigation (2013). Mistakes in doing any death investigation affect the integrity of the evidence in determining the cause of death and in its admissibility in court.

Forensic toxicology is one of the oldest disciplines in forensic science history and dates back hundreds of years. However, the actual understanding and examination of forensic toxicology only dates back for about 200 years. Due to the development of technology, this discipline has been able to progress and flourish.
Forensic Science, recognized as Forensics, is the solicitation of science to law to understand evidences for crime investigation. Forensic scientists are investigators that collect evidences at the crime scene and analyse it uses technology to reveal scientific evidence in a range of fields. Physical evidence are included things that can be seen, whether with the naked eye or through the use of magnification or other analytical tools. Some of this evidence is categorized as impression evidence2.In this report I’ll determine the areas of forensic science that are relevant to particular investigation and setting out in what method the forensic science procedures I have recognized that would be useful for the particular crime scene.
The education level chosen depends on what kind of forensic job you are interested in and what salary you are going for. Most entry-level forensic positions require a bachelor’s degree in forensic or natural science (see Anne 1996). Undergraduate programs consist of toxicology, biochemistry, and criminal justice classes. The American Academy of Forensic Sciences also recommends English classes. This is because forensic scientists need very honed written and oral communication capabilities to write detailed reports and testify to physical evidence in court.
Forensic evidence can provide just outcomes in criminal matters. However, it is not yet an exact science as it can be flawed. It can be misrepresented through the reliability of the evidence, through nonstandard guidelines, and through public perception. Forensic science can be dangerously faulty without focus on the ‘science’ aspect. It can at times be just matching patterns based on an individual’s interpretations. This can lead to a miscarriage of justice and forever alter a person’s life due to a perceived “grey area” (Merritt C, 2010) resulting in a loss of confidence in the reliability of forensic evidence.
As far back as 1832, James Marsh was the first to use forensics at trial to give evidence as a chemist in 1832. Since that time forensic science and evidence has come a long way in various ways and technology to help in determine if the suspect is guilt or not, through such things as DNA testing, blood, and fingerprints. The first forensic police crime lab was created in 1910. The contributions of Dr. Edmond Locard, a French scientist and criminologist, proposed that “everything leaves a trace”. This principle is still valid today as it was so many years ago. No matter how small, the specialized trained technicians and investigators can take these methods and go to a crime scene to get evidence. “Forensic science is the application of sciences such as physics, chemistry, biology, computer science and engineering to matters of law.” (Office of Justice, 2017) These different sciences can help achieve and assist in solving a case. Forensic science has also the ability to prove that a crime was committed, it can find the elements of the crime, it can help place the suspect at the scene and whether the suspect had any contact with the victim. However, in the last several years the techniques and with the use of technology the evidence that forensic science uncovers can also exonerate an innocent individual who has been falsely accused of the
According to the American academy of forensic science, the forensic sciences form a vital part if the entire justice and regulatory system. Forensic science is an enticing career having to do with science and criminal justice, a large variety of schooling is needed to start this job Despite the fact that it can be a dangerous environment it can be an exciting profession to pursue. There are many different fields in forensic science that you can study or major in but they all have the same objectives.
We do have known what forensics is. Forensics that we know is an application of various sciences to answer questions that are important to legal system in which it may be related to a crime. Forensics generallu covering something or methods of a scientific nature and also the rules established from the facts of the event, to do an introduction to physical evidence. This is just a usual forensics. Nowadays, forensics is not just like that, digital devices are everywhere today, helping people to communicate with other people globally, not just between town. We can use that to do some forensics thing too, and find the evidence. It is called Digital Forensics.
“The word ‘forensics’ means “connected with the courtroom”; so forensic science is, therefore, concerned with gathering hard evidence that can be presented in a trial” (Innes 9). Forensic science is a science that is applied specifically to legal matters, whether criminal or civil. “Few areas in the realm of science are as widespread and important as forensic science” (Hunter 12). Forensics is the one science that is most commonly used in everyday life. It is also a branch of science that incorporates other branches of science such as biology, chemistry, and etc. Since it is used almost every day “No one can dispute the importance of the contributions to society made by forensic science; the ability to solve crime is undeniably important” (Hunter 13). Forensic science has given criminal investigation a new edge. “Advances in science have opened the door for more effective evidence discovery, howev...
Serology is defined as the study of serum and other bodily fluids in reference to the diagnostic identification of antibodies in the serum. Serology is used in forensic science as a way of segregating fluids excreted by suspects in criminal acts. Criminal acts with fluid secretion attached to them can range from physical or sexual assault right through the act of murder. Forensic serology deals not only with a variety of body fluids but also, more frequently, with samples that are in stain form and often some stains are degraded and deteriorated, which makes it difficult to successfully analyze them. Over the past 30 years DNA analysis has become more reliable which has led to the release of wrongly accused individuals and reanalysis on a number
