Essays on Chemical Substance

In the Society of Toxicology’s (SOT) public policy statement, toxicology is defined as the study of the interaction of chemical substances with living tissue in the context of the following issues: how they affect a biological organism’s processes, how to reduce the chemical substance’s potential harm to the organism, and what are safe levels of exposure (Society of Toxicology, 1999). The purpose of this paper is to evaluate the SOT’s position statement on animal testing. The topics addressed in the paper are how toxicity levels are determined, the application of SOT principles to course material, ...

Introduction

Spectrophotometry refers to a method that is employed in the determination of the amount of light that is absorbed by a chemical substance. In chemistry, the term spectrophotometry refers to the determination of the reflection or transmission characteristics quantitatively material through a function of wavelength (NIST, 2012). The spectrophotometry analysis is carried out through the light intensity determination as a beam of light passes through a tube containing the sample solution. The process of analyzing solution concentration using spectrophotometer utilizes the fact that light possesses a dual nature. This is where the light may exist either as particle or as a wave (Keller, 2003). Basically, ...

Introduction

Pesticides are substances or a mixture of substances whose main aim is to destroy, repel, prevent or inhibit the action of any pest. A pest is any form of an insect, plant pathogens, weeds, birds, mollusks, nematodes (worms), and microbes that destroy human foods while in the field, during transportation or in stores. In addition, a pest can destroy other human properties apart from food or help spread harmful diseases. Pesticides are classified into five categories: a chemical substance, a biological agent, disinfectant, antimicrobial and a device. Since pesticides find use in both our homes and in farms, they have the potential of causing ...
