Introduction:
A fifteen year old boy abruptly became ill; he experienced fatigue, headaches, tingling limbs, weakness, and weight loss. The only information provided stated that he had been using an acne cream prescribed by a dermatologist as well as an over the counter “beauty cream” to deal with skin irritation. The doctors could not find the reason for the boy’s illness, but interestingly a heavy metal was found in the boy’s urine. What could possibly be the heavy metal and could it have caused such a severe reaction? The objective was to find the cause behind the sudden sickness of this 15 year old boy.
In hopes of finding the cause for his sickness research, diagnostics, and analysis were used to solve the perplexing situation. Hypothesizing that the only scientific explanation for his illness could be that it was a reaction to some heavy metal present in the creams therefore research was conducted to find in which of the compounds that compose the creams is a heavy metal found in. The compounds that are part of the two creams are benzoyl peroxide, acetone, resorcinol, salicylic acid, and calomel. After researching what elements formed part of these compounds, it was found that of those compounds, the first four are organic compounds composed of carbon, oxygen, and hydrogen. Of the first three none contained a heavy metal. However, the last one calomel, which is the common name for mercury (I) chloride (Hg2Cl2), is an ionic bond between mercury and chlorine. Mercury is a heavy metal.
Once the heavy metal was identified, it was needed to ascertain that it was the correct element. To do so, there was a research conducted on cases of mercury contamination and its effects on the human body. The research showed mercury to be...

The primary goal of this laboratory project was to identify an unknown compound and determine its chemical and physical properties. First the appearance, odor, solubility, and conductivity of the compound were observed and measured so that they could be compared to those of known compounds. Then the cation present in the compound was identified using the flame test. The identity of the anion present in the compound was deduced through a series of chemical tests (Cooper, 2009).

Admittedly, when I first chose to explore autism, I figured it would be an easier psychological issue to discuss than bi-polar disorder or schizophrenia. Only after researching autism for an hour or so, I quickly realized this was not the case. Autism may very well be one of the most complex and examined disorders, for it’s a disorder that stirs up tons of questions yet yields very few answers. So what exactly is it? What are the causes and symptoms? Is there a cure? How many people are affected by autism? Is it being properly portrayed in mainstream media? In this paper, I’ll do my very best to touch on these questions and hopefully leave the ones reading with a better understanding of this disorder.
In 1943, Leo Kanner observed eleven children, each with similar behavioral patterns, and published a paper in which he stared,” The condition differs markedly and uniquely from any reported so far” (Miller). Although many cases of autism, and autism-like disorders appeared before throughout history, no one ever properly defined this disorder until Kanner’s paper. The first said to mention the word autism was Martin Luther during the Protestant Reformation, while describing a severally autistic boy, but this is a doubted speculation. The first to medically coin the term autism was Hans Asperger. Even though, he thought he was observing autism, he was actually observing and describing Asperger Syndrome, which doctors realized was a different disorder in 1981 (“Who discovered Autism?”).
The term forensic toxicology is defined as examination of all aspects of toxicity that may have legal implications (James & Nordby, 2009 p. 61). In the past, poisoning was one of the most popular forms of murder. There are countless natural substances in the world that when ingested into the body in high doses, can become lethal to the human body. What made this form of murder so famous is that most poisons mimic common medical diseases, leading physicians to believe a victim died of natural causes (Ramsland, n.d.). Aside from murder, this forensic discipline is also essential for determining accidental deaths and suicides.

Describe the microscopic features of osseous tissue that help long bones withstand compressive forces without breaking.
Lead is considered to be a toxic heavy metal. It occurs naturally in the Earth’s crust. However, it tends to combine with other elements to form lead compounds. (Registry, 2011). Moreover, it has no known function in the body and with excess accumulation, either acute or chronic, will cause a wide array of metabolic dysfunctions by interfering with normal metabolic functions (Analytical Research Laboratories, 2012). From a historical standpoint, most human beings if not all have accumulated some lead in their bodies over the course of their daily lives. In extreme cases, that is, when there is too much lead in the body it is known to cause lead poisoning. In order to fully understand this phenomenon, one must first acknowledge; how lead enters the body, how it is distributed, and how and if it is eliminated.
The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
Toxicology is the investigation of the unfavourable impacts of chemicals on living creatures. Forensic toxicology takes it above and beyond, including various related controls to aid in the location and elucidation of pills and harms poisons and drugs in medico legitimate passing examinations, human execution issues; e.g.,
Arsenic is a very dangerous toxin because of its discreet properties. This element has no color, taste or odor especially when place...
Plasma was considered as the most important part of human blood, which carries out most of the function in relation to transport. Fluids is the major constituent of plasma, with an estimated total protein concentration of about 7.0-7.5 g/dl, as the solid component in plasma, that contain a complex mixture of different proteins which are mainly glycoprotein and lipoproteins. The concentration of plasma protein is largely occupied by Albumin, which is about 3.4-4.7 g/dl as the major protein; this protein will be discourse in further details, (Murray et al 2003). Plasma protein plays a role as biomarkers in diagnosing human diseases, due to their functions as dynamic interface for molecular transport in the body even though, their determination is very difficult because it contain almost 3700 different proteins as found in the literature, (Manley and Gailer, 2009). It was well known from early research, (Himmelhoch, et al, 1966) that plasma protein contain a minute amount of metals, and different technique were used to determine distribution, which will explained in more details. These metals are essential for many function in relation to good health of a living organism, 15 trace element found in plasma were considered of great importance in this aspect which includes but not limited to: Fe, Zn, Cu, Se, Co, I, K, Na, Mg, Mn, Ca, as reported by (Muniz, et al 2013). However, among these trace element Cu and Zn where considered as the most important of all the trace elements in coordinating health activities and were found to bound one metal per protein. The distribution of these metals was found to be high in Plasma Albumin with a concentration of 36.1-53.6 ...
