Today I met with Mr. Schwinnen during opt-out and after school to start my chemical testing for Trial 2. My goal was to finish all of the testing within two hours, but that did not happen. When I started, Mr. Schwinnen showed me a new YSI 9300 Photometer that he order before the new school year. He wanted me to use it to make sure that it worked. I started crushing the nitrogen tablets and putting them into test tubes of my water samples, but when I put the samples into the photometer, it would not turn on. Mr. Schwinnen and I spent about ten minutes figuring out how to change its batteries only to find that it still did not work. Eventually, I switched to the old photometer and things started to flow smoothly again. I finished collecting all of my nitrogen data and got Site 1 and Site 2’s phosphorus levels. Nitrogen levels were very different from Trial 1 to Trial …show more content…
First of all, Mr. Schwinnen taught me how the YSI 9300 Photometer actually worked. Basically, the tablets that I crushed into the water sample change the color of the water according to the certain element that I am looking for. For example, nitrogen turned pink while the phosphorus turned a light blue color. An unaltered sample must be put into the photometer first and light passes through the sample. Then when the colored changed sample is put into the photometer, light is passed through again. Then the machine compares the difference between the amount of light that completely passed through each sample. I also learned that I need to keep better track of what I am doing. For example, when I was letting my samples sit for the tablets to dissolve, I lost track of which site they were from. Luckily I figured it out but that could severely impact my data. Also, I did not fully screw on one of the sample’s caps which made a mess and it could have been easily avoided. Overall, I learned a lot about chemical testing

Animal Testing? Is It Unethical?

...Animal experimentation has been practiced since ancient times, when the ancient Greeks killed and dissected animals for scientific and religious purposes. Vivisection continued throughout ancient times and into the Christian era, becoming a replacement for human dissection when the Catholic Church banned autopsies. Animals were treated as insensitive objects, mere automatons incapable of pain or emotion. By the 1800s, science and medicine were moving forward at unprecedented rates. Germs were discovered and vaccines invented; pills were created and diseases eradicated. Animals were involved in many research ventures, ranging from simple dissections to Pavlov’s classical conditioning experiment. With the advent of the factory line, animal testing became an impersonal study on large groups of animals, from rats to dogs to chimpanzees. The twentieth century brought more medicines and scientific breakthroughs. Psychological studies were conducted on monkeys and cats;...

...Over one hundred million animals are burned, crippled, poisoned, and  abused in other ways in the US labs every year. Today, there are still too  many people that do not see that animal testing is cruel and unnecessary.  “But can these people imagine being squeezed into restraints and forced  to breathe toxic vapours for hours?” (“Chemical” par. 1)”  From cleaning  supplies to harmful drugs and pesticides, chemical substances and  products of all purposes are still being experimented on cats, dogs, mice,  rabbits, chimpanzees and other animals.   Right now, millions of animals are being the victims of human’s  cruelty and inhumanity.  Different kinds of animals are exposed to all  kinds of tortures in order to research. Millions of helpless animals are  being killed each year. According to Humane Society International, there  is a long list of testing procedures that animals can be exposed to in  scientific or commercial testing. “Some of them are forced chemical  exposure, oral force­feeding, forced inhalation, exposure to drugs,  chemicals or infectious disease, tail­clipping, food and water deprivation,  infliction of wounds, burns and other injuries to study healing and even  killing by neck­breaking and decapitation” (“Chemical” par. 4).  Some of  these testings are extremely cruel and require thousands of animals to    suffer. According to Humane Society International, there is a test called  “Development Toxicity” which requires one thousand three hundred rats...

Animal Testing: Scientific Research vs. Our Ethical Values

...Animal testing is a lot more common than we think, testing cosmetics, pharmaceuticals, vaccines for humans, and many more products. But as human beings with a large emotional capacity, there’s always something in us that tells us this isn’t right. Animal testing is a controversial topic, particularly amongst animal rights activists. Animal Testing is used when scientists aren’t sure if the substances used in the materials could cause harm to human beings. While animal testing may provide reliable scientific research, our ethics as human beings proves there are more reliable ways to obtain research, without harming animals. Scientists have been using animals for testing for a very long time, and no one doubted it. Until we saw pictures of these animals, dogs, cats, bunnies, rats most famously, primates, and many other species of animals that we bring into our home, feed and call our family members being tortured, burned with chemicals, and injected with toxic substances and many other forms. Animal testing is rarely performed with the comfort of the animals in mind. Rodents are forced to live in crammed conditions and larger animals are forced to live in spaces so small that they aren’t able to stretch their legs. This causes extreme physiological stress on the animals, causing test results to be inaccurate. Experts say that 90% of tests that prove to be safe on animals turn out to be dangerous to humans. Additionally, animals are often tested for things are not related to...

Guidlines

...GAPS Guidelines GAP.17.5.0 A Publication of Global Asset Protection Services LLC PULP AND PAPER MANUFACTURING INTRODUCTION The modern pulp and paper mill is a complex, high-valued facility. To operate profitably under today’s environmental constraints, a mill must efficiently integrate steam and power demands and chemical recovery systems with the pulp and paper processes. Computer control of all mill processes is the norm. Each step in papermaking — from raw material storage, through stock preparation and papermaking, to finished roll storage — presents special loss prevention challenges. Storage areas pose severe fire loss potentials. Fires, explosions and machinery breakdowns can seriously damage critical process equipment. Pollution control equipment can also cause large losses. Associated with these high property damage potentials are even higher business interruption potentials. In a full process Kraft mill, loss of the black liquor recovery boiler (BLRB) can result in extensive downtime. Continuous digesters and Yankee dryers can also present very large business interruption potentials. This GAPS Guideline describes “full process” pulp and paper mills. Full process mills include pulp, paper and finishing mills, and sometimes converting mills. Figure 1 shows a simplified process flow diagram for a full process mill. Many of the processes described in this section also apply to mills that are not full process. PROCESSES AND HAZARDS Woodyard Operations...

Animal Tested Products

...Animal Testing is Animal Cruelty We, as humans, have made numerous advancements in the world. We have firmly established the scientific evolution, but in doing so, it seems that our ethics and morals have failed to progress as well. The knowledge we have acquired is remarkable, but with it comes responsibility to use it wisely and ethically. We torture and heartlessly kill creatures that we arrogantly consider lesser beings simply at our disposal. For something as simple as eye makeup animals are tortured and blinded by tests performed at the laboratory. Where they are hardly fed, often forced to live in filth, and sometimes have their vocal cords removed to keep them quiet (CAAT). We are systematically cutting down the last forest that provides their shelter to farm cattle; we dump toxic chemicals and sewage into the waters in which they live; we wear and display the tusks of the last few of their species in our homes, and we pour cosmetic products into their eyes and body parts to determine the harmful effects they might cause on humans, even though the physiological differentiation between humans and the animals they use is drastic. On a daily basis most people do not see their own degree of unintentional support towards this global dilemma, but when compiled on paper one must question how mankind can, with conscience, commit these acts which shame us as human beings. Animals possess the same kinds of feelings and emotions as human beings, and without anesthesia, they...

Review

...application must be successful and effectiveness high. As some oil would come ashore, discussion remains on what effectiveness is required to significantly reduce the shoreline impact. A major issue is the actual effectiveness during spills so that these values can be used in estimates for the future. The second motivation for using dispersants is to reduce the impact on birds and mammals on the water surface. The benefits of using dispersants to reduce impacts on wildlife still remain unknown. The third motivation for using dispersants is to promote the biodegradation of oil in the water column. The effect of dispersants on biodegradation is still a matter of dispute. Some papers state that dispersants inhibit biodegradation others indicate that dispersants have little effect on biodegradation. The most recent papers, however, confirm that inhibition is a matter of the surfactant in the dispersant itself and the factors of environmental conditions. It is clear, on the basis of current literature that the surfactants in some of the current dispersant formulations can inhibit biodegradation. No...

Bioremediation techniques have become a major mechanism for removing oil residues on the affected shorelines. Among the different techniques to enhance natural biodegradation by indigenous microorganisms, seeding of new bacteria and fertilizing the indigenous populations have attracted the most interest. The application of nutrients as nitrogen and phosphorus in the form of fertilizers have shown to be most effective in accelerating the biodegradation process and at the same time to be environmentally safe.
