Effects and Toxicity of Nanomaterials Nanotoxicology is an analysis of toxicity of nanomaterials. As a result of the many uses acquired from nanomaterials it has been argued that since nanomaterials are beneficial, the properties can be toxic and dangerous to the cell environment of an organism. This therefore proves that such behavior of properties can easily react with the body tissues which may cause harm and damage of body organs, such as the brain. When such substances are inhaled and enter the internal human organs such as the heart and the lungs, they are likely to cause breathing difficulties in an individual. This shows that nanomaterials have toxins that may be harmful to the life of an organism. The high level of surface to volume ratio of atoms to react with other available orgasms suggests that these nanomaterials can react ferociously with the body tissues which would lead to a wear and tear of the body. This would lead to several effects in the body that can make the body to stop functioning as a result of this technology. For example, apart from the damage identified in the brain, the fish had a change in their livers which signified a physiological difference as an influence of fullerenes. A similar study was conducted by the National Institute for Environmental Studies in Japan by a researcher Shosaku Kashiwada. The main objective of this study was to investigate the risks of nanomaterials on organisms. Fish was used as a specimen in this study which showed results that the fish had accumulated nanomaterials in their gills intestine and the bloodstream. This has raised worries with the increase of nanomaterials around the globe indicating the need of safety for workers and users. In addition, researchers in Swedish Karolinka institute conducted a study that gave an indication that iron oxide showed DNA damage on the human body. It has been identified that industries have taken much interest in this technology where they have used the nanomaterials in cosmetics. These cosmetics have been used by humans who apply them on their skins, but are thereafter is able to penetrate to the inner tissues of the body (Powell & Kanarek 2006, 17). Nano sized titanium dioxide is a good example because it has properties that enable it to sunscreen when exposed to sunbeams that lead to the activation of oxidation which causes much harm to the DNA in human beings. The above information indicates that nanomaterials have toxic properties that are dangerous to the health and surrounding of an organism. The paper indicates that titanium dioxide has been applied in several fields of human life such as the making of tooth paste, plastics and pharmaceutical products. This has been as a result of its property of being transparent which has contributed in making the factory and consumer items attractive and beautiful. This indicates that the nanoscale objects have posed much danger to ...Download file to see next pagesRead More

The major concern after the disaster of the World Trade Center was the airborne toxicology which threatened human health in a radius of more than 6 miles from the site. The dust which issued out into the air due to the collapse of the World Trade Center tower included a wide range of toxic elements and compound having highly injurious effects on human health. The airborne dust from the collapse and fumes from the burning of the towers blanketed Lower Manhattan with dust containing a complex mixture of asbestos,...

In fact, acute myelogenous leukemia (AML) may be the first manifestation of FA (Alter and Kupfer, 2013). AML is the cancer of blood and bone marrow. Like the other cancer types, damage to the DNA, including but not limited to FA genes, is identified as the cause of this malignancy. Because of its rapid progression, treatment must be started immediately (Mayo Clinic, 2012... with...

Environmental Studies: Organ Toxi Due Toxicologists work very hard to understand the different chemicals and organic toxins that can be dangerous to human beings, other animals, and the environment. They work to determine what the tolerance of toxicity is, what the threshold for toxic experiences are, and how to then avoid ever having that level of exposure to that chemical. The thing about toxicants is that there are many different potential, forms, means of exposure, plus reactions due to a combination of exposures that can make determining the safest levels like fitting together a puzzle where the pieces keep changing. Some toxicants are inhaled, absorbed through...

Fluoridation and Toxicity Issues
...’ lecture, he did not shed light on all the aspects of the fluoridation of water. I would therefore like to suggest that there should be a more thorough investigation of the case of the fluoridation of water in Hamilton City. All aspects should be answered especially those involved in the process of the fluoridation of water. One of this is the nature of diseases caused by fluoride, and whether toxicity to fluoride can indeed take place if the chemical has accumulated in the body. However, if one considers the logic behind the explanations of Nokes, then I would like to say that I am convinced that water fluoridation is a good thing. My doubts are mere assumptions. Everything could be fine, as long as the...

Metal Toxicity
...An Essay on Models Used To Predict Acute Metal Toxi Metals are very necessary for living beings but excess of metals and especially free toxic metal ions could be potentially damaging. Osmoragulatory affects of excessive metal exposure can affect ion transporting enzymes of Na+/K+ -ATPase in living beings. Aquatic Metal toxicity depends upon particular water sample's chemical composition such as dissolved organic carbon, oxygen various other elements. Formations of organic and inorganic metal complexes are highly dependent upon the ambient water chemistry (Sunda and Guillard 1976). Metal toxicity of water may be defined as the dissolved metal concentration per unit volume of water....

Toxicity testing
...Toxi Testing Though sub chronic toxi testing and chronic toxi testing are two methods that are used to determine the level of toxi in a subject, there are several differences that exists between these two methods and some of these differences shall be elaborated in this paper. Sub chronic toxicity is used to determine the level of toxicity that arises in a subject for a particular period that is from recurring exposures of some weeks to several months. Chronic testing on the other hand is used to determine the level of toxicity that arises in a subject from exposure for a considerable amount of the life of the subject. Thus, chronic testing extends over a longer period than the sub...

Fluoridation and Toxicity Issues
...Fluoridation and Toxi Issues Teacher               Fluoridation and Toxi Issues (Part The current situation is all aboutthe fluoridation of water or the addition of fluoride to the water in New Zealand. This issue is debatable and controversial because of the benefits that fluoridation gives as well as the disadvantages associated with it. The local elections that will happen soon will determine whether the Hamilton City Council will opt for fluoridation or not. Nevertheless, the disadvantages associated with fluoridation somehow prove that fluoridation still needs further research before it can be implemented. Fluoridation is actually related to the issue of fluorosis. Fluoridation might actually result in the darkening... and Toxi Issues...

The United States ensures that it records it facilities that use large amounts of silicon which can be dangerous to either human beings. This can reduce the amount of this products that are released to the environment( Hoyt and Mason,12). Conclusion While mandating the use of silicon as the leading anti-microbial agent using the nanotechnology in the 20th century.

Cocaine abuse/ toxicity
...is the cause of the drug’s intended effects and developing abuse. It blocks Na channels, which is responsible for its action as a local anesthetic. The most important pharmacological action of cocaine involves blocking the initiation or conduction of the action potential after application to a nerve. The anesthetic effect of cocaine is because of a direct membrane effect. It blocks the initiation and conduction of electrical impulses that occur in nerve cells inside the body by blocking an increase of cell membrane permeability to sodium ions when depolarization occurs. As such, the alternations in synaptic transmissions mediate the systemic effects on the nervous system. Toxicity: it is life threatening sympathomimetic...
