Green Chemistry
Many companies all over the world produce chemicals for their products that are harmful to the environment, human health, and to all living species. Green Chemistry is the use of chemistry for the prevention of chemical pollution to the environment by using chemicals that are benign, or not harmful. The Environmental Protection Agency (EPA) states that the mission of Green Chemistry is, “To promote innovative chemical technologies that reduce or eliminate the use or generation of hazardous substances in the design, manufacture, and use of chemical products.” Green Chemistry contains any aspects and types of chemical processes that reduce the negative effects of certain chemicals, in a way, using chemistry to fight chemistry.
Green Chemistry started after the Pollution Prevention Act of 1990 was passed. The Office of Pollution Prevention and Toxics (OPPT) began to develop ways to make chemical products and processes less hazardous to humans and the environment. There are many principles of Green Chemistry; to prevent waste, to use less hazardous chemical synthesis, design safer chemicals and solvents, make chemicals more energy and cost efficient, reduce derivatives and toxins, prevention of pollution, and accident reduction.
There are many companies...
Pollution prevention includes any method which reduces the amount of toxic substances used and which minimizes waste streams. The laboratory uses solvents, reagents, and standards that are frequently toxic. Some of these substances may escape into the atmosphere by evaporation, and some are carried out of the laboratory by the fume hood system. Minimizing the quantity of the substances used and minimizing their exposure to the atmosphere are important in pollution prevention. Containers of samples, standards, solvents, and reagents shall be kept closed if possible.
Dorothy, the hero in this film learned an appreciation of the life she already had in her ordinary life. Dorothy had complaints about her ordinary world and dreamed of being somewhere else, because she did not have a complete appreciation of her life. She experienced companionship from the Tin Man, the Scarecrow, and the Cowardly Lion who became her mentors and allies in her adventure world. However, these same individuals were her mentors and allies in her ordinary world. Dorothy also experiences real fear and challenges in her adventure world that caused her to grow and mature. She learned to stand on behalf, support and defend others and not only consider her desires. Being away from her Aunt Em, her Uncle and the farm hands made Dorothy realize she already had love on the dusty farm in Kansas and all she needed to do was embrace it. Dorothy’s use of the magic ruby slipper, coupled with her desire to return home to Kansas from the magical Land of Oz, is a classic example of a magic flight. .Although she had been anxious to leave home and sung “Somewhere Over the Rainbow,” her call to adventure, she later expressed her love for her family, executing her magic flight and upon returning to her sweet ordinary world, she exclaimed with a heart filled with love and appreciation: “There is no place like home.” This statement was evidence of her maturity and transformation Dorothy’s joy and appreciation of being back on the farm in Kansas is also evidence that she had mastered both her ordinary world and her adventure
Green Chemistry is not only used in the lab when handling dangerous chemicals, but is also used in everyday life. Some areas where green chemistry may be applied is in medicine, biodegradable plastic, and paint. Pharmaceutical companies are always looking for better ways to make medications have less side effects by making them produce less toxic waste. Also, more and more companies are trying to create products that use compostable or biodegradable materials. Paints usually have toxic fumes that go along with them. Some painting companies are trying to create a product that emits less toxins to better human health and environmental

This case focuses on corporate obstacles to pollution prevention. Pollution prevention can complex especially for large corporations. There are many different forms of pollution prevention including emissions control devices and incremental changes in existing technology. The author reviews the impact of emissions controlled devices, however the focus of the case study is on incremental changes in existing technology. Incremental changes include substituting one or two steps in a production process or relationship changes between production steps. One example of incremental changes that was provided by the author was eliminating chlorofluorocarbons and saving energy by replacing a refrigeration process with a heath exchanger that can exploit waste cooling from another part of the process. There are three critical decision-making stages for incremental changes; identifying a pollution prevention opportunity, finding a solution appropriate to that opportunity, and implementing that solution. The author discusses the three aspects of an organization (culture, ability to process information, and its politics) and how they impact the decision-making stages.
By definition, “biometrics” (Woodward, Orlans, and Higgins, 2003) is the science of using biological properties to identify individuals; for example, fingerprints, retina scans, and voice recognition. We’ve all seen in the movies, how the heroes and the villains have used other’s fingerprints and voice patterns to get into the super, secret vault. While these ideas were fantasy many years ago, today biometrics are being used and you may not even know it.
I enjoyed this experience so much, that I decided to go back to volunteer for Change Point, and will be going there once a week. This experience had the impact it did because I got to connect with the community in which change Point serves and help assist others. By doing this, I gained hands-on experience in which will help me in my future career. I also was able to enhance my skills in being a leader and in communication. The parenting classes that I taught to others not only helped them but also helped me. Each day I was there, I took valuable tools home for myself to be the best mother for my
Production of Green Technology products will greatly decrease the need for trees being cut, as well as mountains and lands being cleared out - Cleaner and less toxic chemicals in the air.
Biometrics is a preset method to recognize a person based on a physiological or behavioral attribute. The present features are face recognition, fingerprints, handwriting, hand geometry, iris, vein, voice and retinal scan. In the early years of the 21st century, we find ourselves persistently moving further away from the stipulation of physical human interface playing a major part of basic everyday tasks. Striding ever closer to an programmed society, we interact more habitually with mechanical agents, unsigned users and the electronic information sources of the World Wide Web, than with our human counterpart. It is therefore possibly sardonic that identity has become such an important issue in the 21st century. Face recognition has been related as the divine Grail of biometric recognition systems, due to a number of noteworthy advantages over other methods of identification.
According to the Biometric News Portal, “if the biometric data are compromised, the user may quickly run out of biometric features to be used for authentication.” In other words, you only have a limited number of body parts that you can use for biometric security. If someone were to get ahold of that, the database will not be able to detect identity theft, so whatever is being protected will be accessible. Physical changes such as getting blisters or major changes like losing body parts due to amputation or sickness also contribute to its unreliability and complicate the recognition process. When there are technical difficulties in the database, they are often hard to fix. Recognition errors exist because some computers make approximations to match someone in the verification process. Other minor obstacles include background noise, dirt or sand on your hands, etc. When government surveillance cameras start including facial recognition, they can easily track anyone. Additionally, an article from Scientific American on biometric security states, “Currently if someone commits a crime, cops can go back and review sections of video. Equip the system with facial-recognition technology, however, and the people behind the controls can actively track you throughout your daily
Hazardous materials are in almost every community placing everyone at some level of contact with various chemicals almost daily as they exist throughout the community and in our households. Chemicals are used for a variety of purposes such as in the water purification process, by farmers to produce a higher crop yield and are used in households and almost every business. Not all chemicals are hazardous but most pose some level of risk to people...
In modern society, humans constantly pollute the environment by using cars, technology, food packaging, and a countless amount of other products. Despite understanding how causing mass amounts of pollution can harm, often there are minimal attempts to correct polluting behaviors, at least until it poses an immediate threat to humans. The idea that the environment is suffering due to our mass consumption through instances of climate change and pollution, is not nearly enough motivation to stop the use of things that may be harmful. In order to address pollution in any respect, there must be an immediate threat to the health and well-being of humanity. Rachel Carson highlights this idea in her
