Health and Environmental Chemistry Essay

The Relevance of chemistry to Occupational Safety, Health an Environment Chemistry is the science of chemicals which studies the laws governing their formation, combination and behavior under various conditions, it is everywhere and without it we would not be a civilized and highly technical world.

Chemistry explains how food changes as you cook it, how it rots, how to preserve food, how your body sees the food you eat, and how ingredients interact to make food. You use chemistry when you use bleaches and disinfectants and even ordinary soap and water. How do understand how vitamins, supplements, and drugs can help or harm you. The importance of chemistry lies partly in developing and testing new medical treatments and medicines. Chemistry is at the heart of environmental issues. What makes one chemical a nutrient and another chemical a pollutant?

How can you clean up the environment? What processes can produce the things you need without harming the environment? We’re all chemists in some way or another. We use chemicals every day and perform chemical reactions without thinking much about them. Chemistry is important because everything you do is chemistry! Even your body is made of chemicals. Chemical reactions occur when you breathe, eat, or Just sit there reading. All matter is made of chemicals, so the importance of chemistry is that it’s the study of everything.

In the SSH act of 2004 Part 2, section 6, it states: “It shall be the duty of every employer to ensure, so far as is reasonably practicable, the safety, health and welfare at work of all his employees” and also the provision and maintenance of a working environment for his employees that is, so far as is reasonably practicable, safe, without risks to health, and adequate as regards amenities and arrangements for their welfare at work. A hazard is any source of potential damage, harm or adverse health effects on something or someone under certain conditions at work.

Basically, a hazard can cause harm or adverse effects (to individuals as health effects or to organizations as property or equipment losses). A hazard is a source or potential source of injury, ill health or disease. Anything which might cause injury or ill health to anyone at or near a workplace is a hazard. There are four main hazards in the work place. Physical Hazard- slips, trips and falls – Slips, trips and falls are the most common of work place hazards. These occur when the surface is wet, contaminated, uneven or due to poor housekeeping.

This can result in serious disabling injuries that can impact an employee’s ability to do his or her Job, often resulting in lost workdays, reduced productivity and expensive worker compensation claims. Chemical Hazard – arise from excessive airborne concentration of mists, vapors, gas, or solids that are in the form of dusts or fumes. In addition to the hazard of inhalation, many of these materials may act as skin irritants or maybe toxic by absorption through the skin. Chemicals can be ingested although this is not the primarily the main route of entry into the body.

Storage and disposal of chemicals – oil and fluid are constantly being used by are improperly disposed of leaving the employees exposed to the excess spillage/ leakage and dangerous vapors, and even the chance of an employee slipping in the excess oil. Employees to washroom facilitates ratio in highly inadequate. There are approximately 54 workers who share washroom facilities of Just 4 stalls for an 8 hour org day. Poor plumbing is also a problem with flooding in the bathroom, the toilets itself is in poor condition in regards of poor seating and no covering for the toilets tanks.

Dust from the extraction fans and a constant stench from the bathroom causing discomfort to the workers. Ergonomically Hazard – poor work station employees working in poor work stations that is not fit for the duties assigned to that worker. The designs of the desk, type of chair , use of the computer all need to be at a certain criteria otherwise employees develop bad posture and back problems, metacarpal syndrome from poor work runtime in their work stations. Analytical chemistry is the science of obtaining, processing, and communicating information about the composition and structure of matter.

In other words, it is the art and science of determining what matter is and how much of it exists. Analytical chemists perform qualitative and quantitative analysis; use the science of sampling, defining, isolating, concentrating, and preserving samples; set error limits; validate and verify results through calibration and standardization; perform separations based on differential chemical properties; create new ways to make assortments; interpret data in proper context; and communicate results.

They use their knowledge of chemistry, instrumentation, computers, and statistics to solve problems in almost all areas of chemistry. For example, their measurements are used to assure compliance with environmental and other regulations; to assure the safety and quality of food, pharmaceuticals, and water; to support the legal process; to help physicians diagnose disease; and to provide chemical measurements essential to trade and commerce. Analytical chemists are employed in all aspects of chemical search in industry, academia, and government.

They do basic laboratory research, develop processes and products, design instruments used in analytical analysis, teach, and work in marketing and law. Analytical chemistry is a challenging profession that makes significant contributions to many fields of science. Instrumental methods of analysis have become the principal means of obtaining information in diverse areas of science and technology. The speed, high sensitivity, low limits of detection, simultaneous detection capabilities, and of analysis, have created this predominance.

Professionals in all sciences base important decisions, solve problems, and advance their fields using instrumental measurements. As a consequence, all scientists are obligated to have a fundamental understanding of instruments and their applications in order to confidently and accurately address their needs. A modern, well-educated scientist is one who is capable of solving problems with an analytical approach and who can apply modern instrumentation to problems. With this knowledge, the scientist can develop analytical methods to solve problems and obtain appropriately precise, accurate and valid information. This text will present; ) the fundamental principles of instrumental measurements, 2) applications of these principles to specific types of chemical measurements (types of samples analyzed, fugues of merit, strengths and limitations), 3) examples of modern instrumentation, and 4) the use of instruments to solve real analytical problems.

The text does not include information on every possible analytical technique, but instead contains the information necessary to develop a solid, fundamental understanding for a student in an upper level undergraduate class in instrumental analysis. Infrared Spectrophotometer Infrared Spectrophotometer Infrared Spectrophotometer is designed to identify or determine the sample by measuring absorption of infrared radiation of webmasters in a region of 4,000 to 400 CERN-l , at various webmasters, when it passes through the sample.

This method uses the property that the infrared absorption spectrum of a substance is characteristic of its chemical structure. Infrared spectra are shown in charts drawn by plotting the webmasters on the abscissa and the transmittance or absorbency on the ordinate. Unless otherwise specified, when the spectrum of the sample is similar in the intensity of absorption at the same waveguides to the spectrum of the Reference Standard or the corresponding.
