Chlordane Case Study

Improved Essays
There is not enough evidence to support the correlation between Chlordane, a persistent organic pollutant chemical, and Kidney Cancer. Chlordane was used on U.S. farmland from 1948 to 1988 until it was banned due to the environmental and human harms that were caused by exposure. However, the use of chlordane is only allowed when treating homes for termites up until 1988. Chlordane has been shown to affect the human nervous system, digestive system, and the liver. Chlordane can enter the body through skin if it comes into contact with contaminated soil. It can also enter the body via the lungs if the clean air has been contaminated. Uptake can also occur at a faster rate into the digestive system and skin if chlordane is an oily mixture. There …show more content…
The fatal human dose is expected to be 6g and convulsive symptoms occur with an oral amount of 2.25g. In a human exposure case study by the Department of National Health and Welfare, there were no illness found among workers that were exposed to chlordane from one to three years. Examination of 22 workers showed no signs of symptoms that were found in animals that were exposed in labs. Some observable symptoms that should have been found in the workers that were seen in the exposed rats included but not limited to loss of weight, anorexia, nervous disorder, and disturbance of vision and respiration. However, none of these signs were seen in the workers over a long period of constant exposure. This study just talked about how little harm chlordane can cause when it is exposed to workers that were creating this chemical. This study was determining if the chemical can cause harmful effects in a short period of time and it concludes that little harm was seen in these workers. According to a epidemiology study by Cornell University, there was a study of 45 white children with brain cancer diagnosed between 1985 and 1989. Two groups of controls were …show more content…
The first case study explained the harms that came from workers making this organic chemical. However, in the third case study it shows the dangers of consuming chlordane and what they lethal dose is in humans. This case used mice to experiment with the danger of consuming chlordane. By consuming chlordane there was a high chance of cancer growth in the mice. The abnormal situation is that only 2 major types of cancer were found to be caused by chlordane; liver cancer and brain cancer. But with these case studies there are no real long term research that passed 4 years. Most of these case studies concluded on liver or brain cancer in an immediate exposure. There was a lack of studies on humans with only a large amount of research on animals. There is no correlation between kidney cancer and exposure to chlordane. Because if any human the ingested 6g or more of chlordane orally will have an immediate symptom of convulsion. If a human was exposed to chlordane through air the only symptoms are minor ones that can easily be treated with a long period of rest. However, if chlordane was exposed to the environment there will be a detrimental affect to other living organisms in the environment, which only require a small dose for it to be lethal. Humans need a larger dose for it to become dangerous. Since this chemical has since been banned in the U.S. for

    Between July 18, 2001 and August 19, 2002, the starting dose assigned to the 539 people on erlotinib was 150 mg. The median survival was 10.6 months in the erlotinib arm compared to 10.5 months in the placebo arm. When the researchers looked at race, age, sex and cancer stage there was no significant survival difference. When they looked at those who smoked versus those who did not smoke, those who had never smoked in the placebo arm had a 22.5 month survival on the erlotinib arm compared to the 10.1 month survival of those who have smoked. In the erlotinib arm, those who had smoke had an 8.4 month survival compared to the placebo arm’s 9.1 month survival.…

    Scientists have never been able to induce an overdose from marijuana on laboratory animals. They were able to tolerate doses of up to 1,000 mg. The Deaths that have been recorded to be the results of marijuana usage were later closely examined and found to actually have been caused by choking on vomit which was not directly credited to the drug. A John Hopkins study done over a fifteen year period has concluded that there were no long-term effects on cognitive skills or actual intelligence in users who smoked about five joints a week. Though most obviously, Americans have no problem with tobacco, alcohol, oxy-cotton, codeine, and many other harmful substances being legally obtained.…

    According to scientists, cell phones were marked as “possibly carcinogenic.”(Trottier 1 ) In other words, it means that there may possibly be a link between the use of cell phones and cancer. However, too little time has passed to detect if cell phones can cause cancer, researchers found no evidence of a link between cell phones and brain tumors and there is no evidence from studies that radiofrequency can cause cancer. More and more evidence is showing up that cell phones do not cause cancer. In one study scientist followed more than 420,00 cell phone users over a 20-year period, the researchers found no evidence of a link between cell phones and brain tumors. There have been hundreds of studies done to the linkage of cell phones and cancer…

    The History Of Vaccination

    The gut also has a lymph system to fight off stronger invaders. Only if one’s body cannot fight the infection off with those various systems does the pathogen enter the bloodstream. On the other hand, with vaccinations they are injected straight into the blood stream completely disregarding all other defense mechanisms of the body (Kurt). This artificial immunity does not even ensure that one will not be infected by a certain pathogen. “Vaccines are never one hundred percent protective because they provide only artificial, temporary, typically inferior immunity compared to what your body would receive from natural exposure to a disease” (Mercola, para.…

    The results of the study showed no patient falls during the trial period, although there were no patient falls two months prior the trial.

    A Columbian study conducted by Luna et al. (2013) found that none of the over 600 subjects, 24 to 45-year-old women who had received three doses of the quadrivalent HPV vaccine, Gardasil, within one year, had HPV 6/11/16/18-related genital warts or cervical cancer 6 years after receiving their vaccinations. While the study was limited to the Columbian women, its results still accurately display the positive effects of the HPV vaccine on those who are vaccinated. In the United States, more than 23 million doses of Gardasil were administered through the end of the year 2008. The Vaccine Adverse Event Reporting System (VAERS) reported 11,916 documented cases of side effects from this vaccine; 94% of these side effects, including swelling, pain, and fainting, were considered non-serious (Pomfret, Gagnon, & Gilchrist, 2011).…

    Studies have shown that 95% of experimental drugs that are safe and effective on humans fail in human clinical trials because they are too dangerous word don 't work (“11 Facts About Animal Testing,” n.d). The animal tests don 't make sure the buyers are safe; companies kill animals not to protect us but to protect themselves in case one of their products blinds of poisons you (“The Life Of A Test Animal," n.d). Animal tested drugs have killed, disabled, or harmed millions of people (“Stop animal testing,” 2006). Diseases that are artificially used in animals in a laboratory are never identical to those that naturally happen to humans; animal species differ from one another a biologically, so it becomes more unlikely that the animal experiment results will correctly solve certain human conditions (“Experiments on Animals: Overview,” n.d). For example, former National Cancer Institute director, Dr. Richard Klausher said that they have cured mice with cancer for decades but it did not work on humans (“Experiments on Animals: Overview,” n.d).…
