Introduction
Pesticides had been used by people and farmers in different continents since early years, some so early that most of them can be traced back to the time of B.C. (Before Christ); natural ingredients like salt and pepper were used as the first pesticides used by human kind. One of the most important and has the most impact pesticides found since the 1900s is DDT. DDT had not only been used by farmers for agricultural purposes and benefits; to regulate and protect the growth of crops and other products, but also used by civilians and military to prevent the spreading of malaria, a fatal infectious disease that is carried by mosquito. Despite the effectiveness, the DDT has been banned in many countries since 1970 due to it's toxic …show more content…
DDT stands for p,p'- DDT or Di(para-chloro-phenyl)-trichloroethane. It has many trade names such as Genitox, Detoxan, and Pentachlorin. It's chemical formula contains fourteen carbon, nine hydrogen, and five Chlorine. It is usually in solid state; crystal power that looks very similar to salt. It is highly water insoluble; however, it is soluble in organic solvents like fat in many cases. DDT is an organchlorine pesticide, organic compound that has five or more chlorine atoms. Most of the organchlorine pesticides get their job done by altering the transmission process of sodium and potassium exchange in nerve cells to paralysis and lead to death to many insects. DDT doesn't have a boiling point, but it can be decomposed. With it's chemical properties of high stability and semi- volatility, half of the DDT can still remain in the air or in the soil for around ten to fifteen years, around one half-life. DDT doesn't just disappeared, it degraded to DDE, DDD, and DDA through degration, which all have similar chemical and toxic properties to DDT. DDT can undergo both oxidation (oxygen reacts with pesticide) and reduction (the other way around) in the …show more content…
Since the DDT can exist in soil, water, and air at the same time for a half-life for fifteen years or more, it can be spread and pass on to plant, insect, and animals easily through food chain. Like the energy pass on in the food chain, the higher position a specie is, the more amount of DDT it would consumed compare to species at the lower level. sea lions and fishes for example, fishes can be affect by DDT and other containment through skin contact and oxygen exchange, but sea lions, predators of fishes, not only are exposed to DDT through inhalation, but it's food sources are also contaminated and are even more exposed exposed to DDT and have bigger influence influences that will alter reproduction, health, and life expectancy. According to the results from experiment conducted you the who (world health organization ), mammals like mice that are exposed to DDT have higher risk of developing developing tumors as the EPA categorized it as a cancer-causing chemical. Not only mammals, aquatic animals, fishes, amphibians, and birds are more likely to gain abnormal symptoms from humans as the DDT has not shown any significant results that shows possibility of getting cancer for humans. Although there are suppressive signs of immune reactions and hormone alteration caused by DDT, deadly as it sounds, but they are not likely leading to lethal results to

Scientific Frauds

...cell researcher who rose to fame however soon it was known that the data was fabricated and the papers were retracted.The general public wasnt affected by it however it does involve and time and money to replicate such results and which is never acheived. So it actually a fraud or a human error, the only difference between a fraud and an error is intention. It could be argued that is there any room for scientists to make errors and yes we all are capable of making errors, they can make errors too however they have the chance to correct such errors before publishing such data instead such papers do see the light of the day, a lot is dependent on these scientific researchers then why is the data tampered and results are achieved per the own needs, a research shouldn’t driven as per the needs of an individual or for any sector [1]. It is based on any actual data which may eventually lead to saving lives or aiming for a better world or better resources or a better environment. Driving factors for scientific frauds Science is a result driven discipline, a ‘Publish or Perish ‘environment which is like the survival of the fittest, where everything is data in facts, figures and tables. It could be an increase in competition to stand out, to publish the best journals, research which atleast looks like a breakthrough and the rewards associated with this are also high as compared to the research budgets [2].

Diabetes Health Campaign Part 1

...or not using insulin properly. Complications from uncontrolled diabetes can result in devastating effects on almost every system in the body. Diabetes is so prevalent that the disease has become a national health objective in the Healthy People 2020 agenda. In 2010 North Carolina had approximately 700,000 adults with a diagnosis of diabetes (North Carolina Division of Public Health, 2011). The unfortunate reality is that approximately one-third of the people in North Carolina have not yet been diagnosed and the screening test, a simple blood test, has only been utilized by approximately 60% of North Carolinians (North Carolina Division of Public Health, 2011). Diabetes is a very costly disease and plays havoc on a person’s body. In this paper the subject of discussion is the public health issue of diabetes and its effect on the communities and population of North Carolina. Diabetes and Healthy People 2020 Healthy people 2020 continues the three decades old national program that is scientifically based and identifies national goals and objective that span over a 10 year period (Centers for Disease Control and Prevention, 2013). Healthy People work to improve health, health promotion, and disease prevention for everyone in the United States (Centers for Disease Control and Prevention, 2013).

Solent Spring

...indirectly, everything in the environment is connected and affected by each other. Silent Spring describes, in depth, the harmful effects that chemical control has placed on all components of the environment. They include: air, water, land, wildlife, plant life, and humans. I will discuss each of these categories as examined in Silent Spring along with my personal analysis. First I will discuss the damage from chemicals released in the air. Aerial spraying of pesticides, mostly DDT, began on a small scale over farms and forests. With the development of new insecticides and the availability of planes from the war, the sky almost literally turned into a shower of toxic chemicals. The justification behind the massive sprayings of the 1950âs was to exterminate exotic species like the fire ant, and the gypsy moth. The spraying was extremely careless, and resulted in heavily populated towns and cities repeatedly being sprayed with DDT (Carson, 1962). Unfortunately, people and wildlife sprayed with DDT along with other chemicals had no warnings and no way to protect them. The government, without consent of those affected, risked the health of those exposed...

Nats Controversy

...another. That is not the point. Many scholarly sources for example, are likely to provide you with arguments that you will use for both sides of your controversy. While you don’t have to worry about choosing the same number of “for” articles and “against” articles, it is important to make sure you have a balanced number of arguments for each side of your debate. Finally, you also don’t need to separate your popular and scholarly sources as they are likely to examine similar issues. You don’t want to be repetitive when describing various arguments, so think about a way of effectively organizing the arguments you will presenting. Your paper is essentially going to be divided in two parts. The first part will be about describing the arguments on either side of the debate. I call this the descriptive component of your paper. The second part of your paper is the analysis. You will be analyzing two things. First, I want you to compare and contrast how your topic is presented in scholarly versus popular media. Think of areas like language (simple versus complex), use of references, and length of article as a starting point for your analysis. Make sure to use examples in your analysis. For instance, if you tell me that scholarly sources are harder to understand than popular ones because of language, provide an example of this from your own sources. The other thing I want you to analyze is how your topic relates to any one or two of our course themes and/or theories. This is unit one material...

...INTRODUCTION                           Soil is the thin layer of organic and inorganic materials that covers the Earth's rocky surface. The organic portion, which is derived from the decayed remains of plants and animals, is concentrated in the dark uppermost topsoil. The inorganic portion made up of rock fragments, was formed over thousands of years by physical and chemical weathering of bedrock. Productive soils are necessary for agriculture to supply the world with sufficient food.                         A soil pollutant is any factor which deteriorates the quality, texture and mineral content of the soil or which disturbs the biological balance of the organisms in the soil. Pollution in soil has adverse effect on plant growth.                 The introduction of substances, biological organisms, or energy into the soil, resulting in a change of the soil quality, which is likely to affect the normal use of the soil or endangering public health and the living environment. Soil contaminants are spilled onto the surface through many different activities. Most of these are the result of accidents involving the vehicles that are transporting waste material from site of origin to a disposal site.                         Soil pollution is particularly dangerous for the environment and our health because soil, either in the mountains or in the plains, contains the largest part of the water we drink and produces all the food we need. There are many types of soil pollution...

Our Stolen Future

...Name: C.T.B. Assignment: “Our Stolen Future” Date: 12/03/2012 The Book “Our Stolen Future” is considered to be a sequel of “Silent Spring“, a Rachel’s Carson classic work, a clarion call to protect the American public from manmade synthetic pesticides that cause genetic mutations and cancer. Carson not only described how persistent chemicals were contaminating the natural world, she documented how those chemicals where accumulated into our bodies. Since then, studies of human breast milk and body fat have confirmed the extent of our exposure. Human beings in such remote locations as Canada’s far northern Baffin Island now carry traces of persistent chemicals in their bodies, including notorious compounds as PCBs, DDT and dioxin. Even worse, in the womb and through breast milk, mothers pass this chemical legacy on to the next generation. “Our Stolen Future”, the scientific discovery of Theo Colborn, Dianne Dumanoski and John Peterson Myers, takes up where Carson left off and reviews a large and growing body of scientific evidence, linking synthetic chemicals to aberrant sexual development and behavioral and reproductive problems, such as low sperm counts, infertility, genital deformities, hormonally triggered human cancers, like those of breast and prostate gland, neurological disorders in children such as hyperactivity and deficits in attention. The quality of men's sperm declined steadily in the early years of the 21st century until hardly anyone could reproduce in...

I thought I would pick out and would choose one major lawsuit and write about that in my final paper. Now, I am going to give you a brief summary of the history of the company. Monsanto was founded by John Francis Queenie in 1901, in St. Louis Missouri. He named the company after his wifes Maiden name Monsanto , John was a 30 year veteran in the pharmaceutical business. He invented quite a few things One of his first products was artificial sweetener called saccharin. That was sold to Coca-Cola. By the 1940’s the company was a major producer of plastics which included polystyrene and synthetic fibers. The scientists from Monsanto had a breakthrough research on catalytic asymmetric hydrogenation and they were the first company to mass produce LED lights. Monsanto Company is headquartered in Missouri. It is a leading producer of genetically Engineered seed and the herbicide glyphosate, which is marketed under the brand name of Round-up. This is what I’m generally concerned about, I use this product Roundup for my weeds and have heard that glyphosate is safe and non-toxic, from the research I have been doing that’s not the case. Glyphosate is an active ingredient in some common herbicides used in farming and gardening. This chemical is sprayed on the roadside when people are driving, schoolyards and sports Fields, exposing kids...

Endangered Species Act Commentary Paper

...Mo Yi Lam BISC_102 Professor Kiefer Nov 30th, 2010 Final Paper (Summary of Endangered Species Act) Endangered Species Act “What is an endangered species?” is a question that needs to be addressed before getting known of endangered species act. An endangered species is a population of organisms which is at risk of becoming extinct due to three possible reasons: it is few in numbers. According to the theory of Exponential Growth Curve proposed by Malthus, a lower population tends to have a lower reproductive rate and thus a higher risk of going extinct; or a species is threatened by changing environment. A species which fail to adapt a new environment by means such as mutation which creates new “fitting” genes tends to have a higher risk of going extinct; or it is affected predation parameters. In a community, defined as a group of interacting organisms sharing a populated environment, the population of a species is highly dependent on one another. If the predator population of a species is high, this can limit its reproductive rate and thus the population growth. International Union for Conservation of Nature (IUCN) is an organization which “helps the world find pragmatic solutions to our most pressing environment and development challenges.” (IUCN “About IUCN”)According to one of its reports, the endangered species is 40% of all organisms, which has reached the stage of alarm that endangered species conservation policies must be implemented in no time. ...

Identify the characteristics that are shared by these toxins and characteristics of these toxins make these toxins vulnerable to toxicity of these specific systems? Central Nervous System Environmental contamination has exposed humans to various metal agents, including mercury. This exposure is more common than expected, and the health consequences of such exposure remain unclear. Mercury in the past was used in a numerous different activities, and now, exposure to this metal from both natural and artificial sources is significantly increasing. According to Azevedo, et al (2012), numerous studies show that high exposure to mercury can induce the following changes to humans such as the central nervous system, potentially resulting in irritability, fatigue, behavioral changes, tremors, headaches, hearing and cognitive loss, dysarthria, incoordination, hallucinations, and death. Endocrine System According to the Canadian Centre for Occupational Health and Safety, Endocrine disruptors are found in synthetic chemicals used in industrial solvents, lubricants, and their byproducts such as polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs), and dixons.

Position Paper

...The Position Paper Analysis 3.1 Composition II There is a common ground that all of human nature shares, and that is the fact that we all must eat to survive. Food. It is what keeps us alive, and is undeniably one of the single most important factors of our existence. Without it we would perish. So, how does the world manage to mass produce enough food to feed the billions? Mass production of crop cultivation on a large scale. In order to do this successfully and provide food for the populations there are a few primary issues which must be addressed. One of the main issues the farmers of the world must deal with is the problem with crop destroying insects and invasive plant species. Pesticide is used to identify both insecticides and herbicides, or (as I like to refer to them) bug and weed killers. Although pesticides curb the effects of insects and weeds in food cultivation, the detrimental health issues concerning the effects of pesticides continues to increase; therefore, pesticides should have stricter standards imposed upon their use, and more focus should be made towards developing alternative methods and safer solutions. Depending on location, environment, weather, and many other variables there is a great need to protect the world’s crops from the devastating effects of bugs and weeds. Certain species are capable of terminating the growth of necessary food sources. Of course humanity would react as alarmist and jump to an immediate solution of “Kill...
