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

Arguments in favor of BPA’s continued commercial use center on the assertion that each exposure is so minimal that the lifetime risk to human health is not serious enough to call for a ban on a chemical with a variety of commercial applications. While the argument appears to focus on degree of exposure rather than on a debate about whether or not chemicals do, in fact, have the potential to leach, vulnerabilities in certain individuals make the specific “safe” exposure level difficult to identify definitively.

The movie documentary Tapped has opened not only mine, but a group of society’s eyes to what harm we are actually causing upon on ourselves with an action so little as to drinking out of plastics bottles. People have been drinking out of bottle waters assuming that what the are drinking out of is safe but once over thousands of plastic bottles were tested huge concerns grew. Studies show that varieties of bacteria and chemicals were found, causing cancer and other illnesses. One of the many harmful chemicals found in these plastic bottles is Styrene which causes a cancer causing agent and also could possibly cause adverse reproductive effects. Investigators also found three different types phthalate, Diethyl phthalate, Dioctyl phthalate that

This shows that not only does BPA affect the current people of today’s society, but it will affect the future generations of our society, our children’s society and even their children’s society. This chemical is seen by the greed of very wealthy businessmen who have a goal of profiting off of us: the beginning middle class. Furthermore, Brent Bauer states, “Epoxy resins are used to coat the inside of metal products, such as food cans, bottle tops and water supply lines. Some dental sealants and composites also may contain BPA” (What is BPA?). Bauer is showing that no matter what we do, no matter what actions we may try to take in order to avoid BPA getting into our bodies and causing to self-implode, it will not work. The monster is everywhere. It is possible to use products that do not contain such high levels of BPA, but for just about everything: desks, water bottles, food cans, and even dental procedures can and will put us all in danger of feeling the wrath of the beast. BPA is very close to all of us, but I do believe it has played a significant role in my grandfather’s battle and recovery with

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.

is a difficult chemical to escape -- it's in so many plastic products from water bottles and sippy cups to contact lenses and toys. Controversial studies linking BPA to health risks, particularly reproductive risks, prompted companies to go the "BPA-free" route. But new research from the University of California - Los Angeles (UCLA) Health Sciences says not so fast: BPS (Bisphenol S), a replacement for BPA that technically makes products BPA-free, is probably not safe either.

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.

BPA is short for a chemical called bisphenol A that is used in many household items that we use every day. It is in food and drinking cans, as is in water pipes that carry our drinking water (Laposata & Withgott. 2012). It is also in plastics we use for food storage, baby bottles, and even children’s toys. This chemical is also used in CD’s and DVD’s; be that as it may, this is a very odd mix of items to find one chemical in, some we eat from, and some we use. The chemical is actually used to stop cans from rusting and food free from bacteria, as well as to harden plastic; with this said, why is it we put this in our bodies (“Baby Bottles And Bispenol A (BPA), n.d.)?

Obesity is a problem many people encounter, but is BPA contributing to it? There have been many experiments to test that question. BPA-Glucuronide is a chemical that researchers find in many urine samples. The University of Michigan conducted their own experiment. They found that adult with high levels of BPA have an increased chance of acquiring diabetes, cardiovascular disease and may become obese. Other researchers conducted experiments and found that BPA-Glucuronide led to a significant increase in acquiring fat. There is a strong correlation between BPA and obesity.

Look all around you and there is at least one or more items that includes plastic. In these plastics there are chemicals called endocrine disruptors. Endocrine disruptors can act like the hormone estrogen in a person’s body. The two main and common endocrine disruptors are BPA and phthalates, which are in a lot of products that we use every day. These chemicals negatively affect women, men, children, and even fetuses. So, there has been a lot of controversy about these plastics and the chemicals inside of it. There are multiple people that think that there should be a strict protocol when it comes to these chemicals, like BPA and phthalates. Linda B. White who wrote “Plastics: What’s Dangerous, What’s Not”; Sheldon Krimsky who wrote “Plastics

As reported by the National Institute of Environmental Health Sciences (NIEHS), To prevent exposure of BPA do not microwave plastic, even though BPA is heat resistant, it can break down over time. Reduce use of canned foods, cans are lined with BPA plastic to keep the contents fresh. Use glass/porcelain/stainless steel for hot contents since they do not contain BPA. Buy BPA free baby bottles, infant products are notorious for containing high levels of

This news article is describing how or if drinking bottles that contain BPA effect your urinary levels. In a current study of college students they monitored the exposure or BPA. At first they could only drink cold beverages from stainless steel bottles. Then for a week they could only drink cold drinks only from two new research-provided polycarbonate bottles (McGovern, A 406). They took urine samples of the participants to compare it to the urine samples in the NHANES study. To McGovern, who wrote this article does say that not all polycarbonate plastics contain BPA (McGovern, A

"In fetal mouse prostate you can stimulate receptors with estradiol at about two tenths of a part per trillion, and with BPA at a thousand times higher," vom Saal says. "That's still 10 times lower than what a six-year-old has." Mice with the same amount of BPA measured in urine the later developed cancer and other health issues. There's also evidence from the journal of reproductive doxology that found that “humans must be exposed to levels of BPA at least 10 times what EPA has deemed safe because of the amount of chemical detected in tissues and blood samples.” In 1997 Japan began to use other natural resin instead of BPA after their scientists show the leaching of BPA into baby bottles. They did point out though that some of these same studies have shown that other foods we eat containing estrogen like chemicals including some soy products have shown similar effects.(biello,2008) One of the reasons for our quick excretion of BPA is our body turns it into glucuronide, and it is excreted through feces and not urine, which is why the amount of BPA in urine indicates far higher exposure than the actual amount in the urine. Also most is excreted within 6 hours and almost most all by 24 hours.(Carwhile, 2010) There is also studies that indicate that BPA in women can act like estrogen in the body which increases the risk of breast cancer and cancer cell growth. (biello,2008) It's also been linked through animal studies to cardiovascular disease and diabetes, early onset of sexual maturity, problems with development of tissue organization of the mammary gland, reproductive tract lesions, increase prostate size, and decrease sperm production in offspring.(Carwhile, 2010) Even short periods of exposure can cause infertility in female

heorizing that BPA was not the only EA chemical, scientists have tested hundreds of everyday products of varying kinds of plastic from numerous retail sources to determine if they had estrogenic effects. Products included food wrap, deli containers, hard or flexible packaging, plastic bags, baby bottles, and reusable plastic water bottles. Most of these products were labeled BPA-free. The exact chemical composition of almost any commercially available plastic product is unknown. A single part may consist of 5-30 chemicals, and a plastic item containing many parts may consist of 100 or more chemicals, almost all of which can leach from the product. Researchers have used this information and extracted chemicals from the various plastic products

Bisphenol A is an endocrine disruptor - a substance which interferes with the production, secretion, transport, action, function and elimination of natural hormones. BPA can imitate our body's own hormones in a way that could be hazardous for health. Babies and young children are said to be especially sensitive to the effects of BPA.
