Recommended: Importance of forensic chemistry
Biochemistry is the study of the organization and chemical reactions of material in live organisms. Biochemistry became a separate division when scientists mixed biology and different aspects of physical chemistry and started to study the processes of living things, such as energy transfers, hereditary organization, and much more. Biochemistry includes the sciences of neurochemistry, biophysical chemistry, and a very interesting subdivision: forensic chemistry.
Have you ever watched late night crime shows, such as CSI, NCIS, or even a mystery show, such as Sherlock? Forensic chemistry plays a vital role in these popular shows, and in real life. Forensic chemists deal with analyzing crime scenes or evidence found at the scene of a crime. The evidence they examine can range from DNA (blood, hair, other bodily fluids), fabrics and other clothing substances, figerprints, and almost anything found on or in a body. In January of 2015, a team of forensic chemists solved the mystery of a 700 year-old Italian warlord’s death! From blood, to mysterious powder, to a dead body, forensic chemists tackle it all.

It takes a lot of work to become a forensic chemist, but the payoff is usually worth it.
Almost all forensic chemists work in a federal lab, trying to analyze samples of substances such as DNA and match them with unknown specimens, usually to determine the suspect of a crime. Of course, some forensic chemists take up teaching or administrating jobs, but they still have fun teaching others about their crime solving process. Some forensic chemists are lucky enough to become promoted to crime director, and is in charge of managing other forensic chemists and writing case
reviews. • Some forensic chemistry careers in North Carolina include: Criminalist DNA Analyst, in Charlotte; Scientific Director/Laboratory Director, in Asheville; Crime Laboratory Deputy Director, in Raleigh; Forensic Pathology Fellowship at East Carolina University, or even the NC State Crime Laboratory. • NC State, UNC Wilmington, Fayetteville State University, Western Carolina University, and East Carolina University have degrees available in forensic chemistry. • An undergraduate degree in forensic chemistry is mandatory for work in crime laboratories, with a lot of experience in biology, mathematics, and chemistry. More technical careers, such as lab managers and supervisors, might need a master’s degree. A doctorate is commonly suggested for promotion to jobs such as lab director, but it is mandatory for forensic research positions at universities. • Studies reveal that the average forensic chemist makes $45,580 annually. Simple laboratory assistants make around $32,000 annually, lab technicians make around $45,000, crime lab analysts make almost $80,000, and those in lower positions, such as researchers at universities, make around $10,000 to $20,000 less depending on position level. • While a career in forensic chemistry is difficult to find in Caldwell County, North Carolina, careers in its original field, biochemistry, are much more plentiful. • For instance, a position in biochemstry can be found in Greer Labs, located in Lenoir, North Carolina. From previous information, we can infer from the undergraduate degree requirement in Chemistry or a related field (Biochemistry), and the job description of working in biological tests and analyzing data, that their offered career falls under that of a laboratory technicians, and once trained, would make an estimated $45,000 annually. Several other factors can influence this, but can safely assume the salary. I hope you enjoyed learning about biochemistry, and even more in-depth, forensic chemistry.

Forensic Science Introduction: Someone in a restaurant has suddenly fallen ill and a mystery powder has been discovered with the victim. As the chief investigator, your duty is to identify the mystery substance through a lab. In this lab, it will consist of five known compounds and one unknown compound. Your job is to distinguish which one out of the five substances is the mystery powder. To figure out the mystery matter you will have to compare their physical and chemical properties and match them with the appropriate compound.
Forensic science is a key aspect of Criminal Justice that helps rid the streets of lunatics and murderers. One of the most important fields of forensic science is blood spatter analysis. Under the Crime Scene Investigation, analysts gather the information that could eventually lead to a victim’s killer. Basic and complex information can be found when analyzing blood. We can learn what kind of weapon was used, the time of death of a victim and other important facts that can help a case. The pattern that the blood gives off give forensic scientists the tools that they need to help solve cases.
I chose to research the profession of a homicide detective. This profession interests me because I find solving a puzzle satisfying, by picking up the pieces (evidence) and fitting them together I can solve the mystery of the homicide. This of course is something I will have to work toward, as I cannot become one right out of the gate. First I will have to be a police officer. I have to be a police officer first because I need to gain experience in the criminal justice world and with victims/ suspects. Depending on the town I choose to pursue my career in I could have to start as a patrol officer or at a jail. I am doing things now to try and set myself apart from other candidates so if the time does ever come for a promotion I can be one step
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 has contributed to our world a great deal. People often misunderstand Forensic Science and believe it is much more capable than it really is. As a matter of fact what you see on T.V. is around 80% false or over exaggerated in some way. To Start of, Criminal Investigation is the largest and most known form of Forensic Science. Some of the more known areas include; Fingerprinting, Ballistics, DNA Identification, Fiber Samples, Computer Animation, Documentation analysis, etc. To get this out of the way in the beginning, what you saw on last night’s law and order is far from the truth. Things they do in a matter of hours take months at a time, and most of the time aren’t even plausible concepts.
In today’s time, modern Crime Scene Investigation has increased rapidly. From throughout the late 1900’s and in the early 2000’s (Taylor 1). For all of the evidence that they find, a solid foundation has formed over the thousands of years of Crime Scene
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.
Crime scene investigators, also known as CSIs, have played an essential role in protecting citizens, by proving who is guilty, and who is innocent. CSIs use a large amount of Science and Math skills to solve crimes, resulting in a decent income. They are specialized in forensic science in order to examine crime scenes and recover important evidence (Career Cruising).
Forensic scientists work in labs where they examine, identify, and interpret evidence collected in crime scenes. Crime scene investigators collect evidence and pass it to a forensic scientist who uses the items in numerous ways to help catch criminals. Forensic scientists must also record the evidence and any tests run on it in detail to prove the truth in court. A forensic scientist also has to be able to present his or her physical evidence verbally in court, so a strong communication background is important. The first step taken to become a forensic scientist is to first pass the education required to become one.

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
Forensic science is specialized in finding proof and evidence to analyze and search for clues. When crimes are done, criminals frequently leave behind evidence at the crime scene. Crime Investigators (AKA- CSIs) and Medical Examiners (MEs) the inspect the evidence left at the crime scene for leads to who did what. They try and rebuild the scene using the evidence and proof that they have. Forensic science has played a great role in finding evidence for crimes in history because it helps find the person who did wrong, the perpetrator, and it helps bring justice to the case. Forensics now are better than before because technological advances like DNA testing has been made, which takes forensics to a whole new level.
“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...
Though many people fail to realize it, chemistry is a subject essential to everyday life, due to the fact that it is the branch of science that deals with the identification of the substances of which matter is composed. But what we must understand is that everything in the universe is composed of matter, hence chemistry is necessary in learning more about the world and universe that we live in. There are many careers and fields affiliated with chemistry that people pursue to learn more about the composition of the universe, but for now, let us examine the logistics of three of these careers. These three careers involving chemistry are geochemistry, environmental chemistry, and chemical engineering.
Forensic investigations require skills of specially trained scientists, police, engineers, doctors and others. “These investigators observe all types of evidence, from weapons to bloodstains and from computers to bugs” (Erzinclioglu 5). The greater the evidence against a person, the greater the chance of conviction.
