Does Bpa Be An Endocrine Disrupting Compound?

Between 2002 and 2005 alone, the amount of chemical substances produced or imported in the United States increased from 42 billion pounds per day to 74 billion pounds per day. The amount of chemicals in commerce in the United States has increased from 62,000 grandfathered chemicals in 1976, to almost 83,000 in 2008, a difference of more than 20,000. Of this 83,000, the EPA has only been able to ban or restrict five chemicals under TSCA: PCBs, dioxin, CFCs, hexavalent chromium, and asbestos. Additionally, the EPA has independently tested only 250 of the 83,000 registered chemicals in commerce in the United States. Richard Denison, a Senior Scientist for the Environmental Defense Fund explained these incredibly low numbers by stating, “TSCA places an impossibly high burden on EPA before it can act to control a chemical.” In fact, under TSCA, “the EPA can’t even require testing to determine whether a risk exists without first showing a risk is likely.” For that reason, a large majority of chemicals used in the United States have never been tested for health and environmental effects. Studies have shown that due to the proliferation of these chemicals into homes, workplaces, and schools, the average American has a detectable concentration of 300 environmental chemicals. Among other issues, many of these chemicals can affect brain and organ function and cause cancer. Consequently, it is clear that

The overall food contamination by Bisphenol A is unknown, but the nutrition/ health impact of this chemical is an important subject to be discussed for all individuals. The main aim of one study recently analyzed was to assess the reproductive impact of BPA leached from regularly available polycarbonate plastic containers. The bottles specifically chosen for testing were those that were used by children. The migration of BPA occurs in polycarbonate plastics (i.e. water bottles and baby bottles). Toxicology reports show society the importance of evaluating these products before purchase and consumption as a consumer. For a particular experiment, researchers used Daphnia Magna, a small flea that cleans and absorbs particles that infect the solution they are placed in, and bred them in the polycarbonate containers. A control group was created using water bottles without the infection of these creatures. A GC-MS machine to detect the level of BPA released by each polycarbonate plastic then evaluated the water. An increase in the reproduction of BPA was detected when the Daphnia Magna were bred inside the container. Although these organisms effected the leaching of Bisphenol A, the GC-MS was able to detect, through the control group, that BPA is released without DM. An Eco toxicological effect was observed through all of this testing, and provided evidence to substantiate the fact that Bisphenol A is leached from polycarbonate plastics. The BPA was further analyzed in the Daphnia

It is nearly impossible to comprehend that products and items that we as a society use everyday can create such a catastrophe with our bodies that cancer, autism, and even the reproductive system is affected by these monsters. Even though there are thousands of chemicals that can harm our society, BPA is looked at as one of the ugliest monsters out there today.

In the year 2011 there were many reports in the media regarding bisphenol A (BPA). BPA is a hormone-disrupting chemical linked to adverse health effects like cancer, infertility, diabetes, obesity and ADHD (Newbold, 2009)

This is because the chemical has one of the most common environmental chemical exposures to humans. Abbreviated “BPA”, bisphenol A exposure, has been linked with several mechanisms that are involved in the development of cardiovascular disease, this comprises of weight gain, insulin resistance, thyroid dysfunction, endothelial dysfunction, and oxidative stress (NHANES 11).Public health places emphasis that the health of populations should be considered by reducing the quantity of bottled water they consume. Data should be collected for the purposes of policy decision making and deciding the best ways the consumption of bottled water should be curtailed Considering that an endocrine-disrupting chemical, BPA has been shown to have estrogenic and thyroid hormone that disrupts the effects of experimental studies. This owes to the fact that there are significant relations between childhood obesity and the type of water such children who get infected by the disease consume. The venture hence becomes a serious concern because people, specifically Americans, have been unknowingly poisoning themselves and their children with the prior mentioned chemical. This has been championed by the use of BPA contained in bottled water. Notably, only reduces human consumption of this harmful chemical which is found 93% of the American adult

My mother always told me that BPA was a bad substance. She was a nurse who worked in the medical field for forty years, and was always scrutinizing medicines, vaccines, and chemicals. Every school year when I picked out a plastic water bottle, she had to check it to make sure it was BPA-free. Like with anti-depressants, my mother was afraid it would mess with my hormones, especially since I was just a developing girl.

The researchers suspect that overstimulated neurons could lead to early puberty and interrupt the natural reproductive system. While this study focused on zebrafish, it could speak to larger issues. Could the rise in BPA and BPA-free products explain the "rise in premature human births and early onset of puberty over the past couple of decades," in the United States? Health Day http://consumer.healthday.com/encyclopedia/pregnancy-33/pregnancy-news-543/premature-births-on-the-rise-643869.html reports that over 500,000 American babies (or 1 in 8) are born prematurely and the rate of premature births has increased 36 percent since the 1980s. Puberty is also beginning much earlier for girls and boys, some as young as six.

Bisphenol A (BPA) is a monomer used to synthesize polycarbonates and epoxy resins for the manufacturing of products to which we are exposed in daily manners. BPA is considered a xenoestrogen because of its high affinity for estrogen receptors and related receptors, also, because it is known to have a disruptive effect on blastocyst implantation when ingested or injected in doses 10,000 times the effective dose of E2.

Groups 2, 3 and 4 were given BPA orally. In order to administer the BPA, BPA was mixed with 150-200 μl of olive oil. Each of the rats that received BPA were given 2 μg/kg body weight per day orally for 14 days. Group 5 received the same volume of vehicle.

It would be expected that as out lives increase in comfort and hygiene with the creation of plastic, disposable and sterile things, the decent of life threatening diseases would follow. This has been the case with some diseases, but not all. In the last 45 years, there have been increases in childhood brain cancer, Asthma, Leukemia in children, early onset puberty, ADHD, genital deformities in baby boys and life-threatening birth defects. While genetics may be able to account for some of that increase, the rise has been too high in such a short amount of time for there to be no other external factors. The biggest culprit? Chemicals. In the last 50 years, there has been a 2000% increase in the use of chemicals in industry; most of these chemicals have never been tested for safety. One of these chemicals is Bisphenol A (or BPA), to which hundreds if not thousands of studies have linked to some of these conditions and more, which is a HUGE problem. Thanks to all these studies, we know that BPA is detrimental to our health, and so in order to benefit the long-term health of students and faculty, Wayne State should ban BPA products sold on campus, and replaced them with safer alternatives.

Studies have been completed, showing that 10% of birth defects are caused by chemicals in industrial products.("Birth Defects and Environmental Causes." ) The chemicals in industrial products come from many things, however, food is one of the largest contributors to birth defects. Therefore, it is important that consumers understand how the industry 's use of chemicals can affect one’s, health through their use of packing, synthetic chemicals, and the alternatives to chemical filled foods.

There are chemicals plastic products and in cans. This chemical bisphenol-A (BPA) are in many products people use every day. People are exposed to this chemical on a regular basis except in small amounts and it is harmless but since it is in many products that we use it can cause harm to the human body. Some of these products are canned food, plastic, receipts, and it is in the air. Exposure to BPA can cause many health problems overtime because it is a carcinogen. BPA should be banned from being in products because of how poisonous it is to others health.

During recent years, numerous newspaper and magazine articles have suggested that humans may be at risk because small amounts of well known environmental contaminants, such as dioxin, PCBs and DDT, can affect hormone levels. Hormones are produced by the endocrine system as regulators of biological function in target organs. Because hormones play a critical role in early development, toxicological effects on the endocrine system often have an impact on the reproductive system. The term endocrine disruptor is used to describe chemicals that can mimic hormones and may either enhance or counteract their effects. It has been suggested that these hormone changes can, in turn, lead to a variety of health problems

Many scientific researchers have said that our environment has been filled with toxic chemicals, which us humans have had a part of. There are many different issues that should concern us surrounding these toxic chemicals. The major concern is that many of these toxic chemicals have been claimed to be causing damage to the health of humans and even other life forms. Another concern is that most of the theses toxic chemicals have just recently been produced; and by our environment changing everyday there is no telling what effects these toxic chemicals may have in the long run on the public 's health. Just about all of these toxic chemicals exist in the way they do because of humans. As humans we practice a lot of different activities that cause toxic chemicals to pollute our environment such as, agriculture, industrial, and many domestic activities as well. Many of the toxic chemicals that we produce and use don 't get used in a effective way, which causes them to be wasted, left abandoned, and disposed of. When toxic chemicals are not disposed of properly they effect the environment and the public 's health in a negative way.

In 1984, the Cosmetic Ingredient Review (CIR) evaluated the safety of methyl, propyl, and butylparabens, stating that they were “safe for use in cosmetic products at levels up to 25%,” which is a generous limit, considering the approximate level for parabens ranges from .01 to 3%. However, there are still claims that parabens do more harm than good. The U.S. Environmental Protection Agency reported in December of 1999 “the chemical preservatives called parabens—methyl, propyl, butyl, and ethyl—displayed estrogenic activity in several tests.” Essentially, they found that parabens have the capability to mimic the body’s own hormones, which can lead to disruptions in the endocrine system, developmental and reproductive toxicity, allergies, and immunotoxicity. Even though parabens occur naturally in low levels in foods, like strawberries, blueberries, onions, carrots, etc, they are metabolized when consumed, making them less estrogenic. Yet, when the
