Bisphenol-a (BPA) is found in many beverage and food containers, including baby bottles. The main use for BPA is in the production of plastic items, like water bottles, computer cases, sunglasses and canned and beverage goods. In addition, this a component of this chemical is used in making the heat sensitive coating on thermal paper possible for printing. Also, polycarbonate plastic food containers are made from the chemical BPA. These food storage containers provide a durable, tough, see through and shatter free way for restaurants to store food. In addition to contributing to safety, containers made with BPA plastic provide us with a low-cost option that can be used for a long time.…
om the US Food and Drug administration(FDA), BPA can possibly cause hazards to foetuses, infants, and young children. The adverse effects of BPA will be explained in details in plastics No. 7.…
Following metabolism the metabolites are excreted in the urine and faeces. No data on the acute effects of B(a)P in humans were identified and few studies were reported in animals. Following acute exposure of rats to B(a)P, effects on the liver were observed. Following chronic exposure in an occupational setting a decrease in lung function was reported, as well as chest pain, respiratory irritation, cough, dermatitis and depressed immune system, although in most cases it was not possible to evaluate the contribution of B(a)P to such effects. In animals, few adverse effects were observed in rats or hamsters exposed to B(a)P via inhalation. Following ingestion, myelotoxicity was observed in poor affinity Ah-receptor mice but not in high affinity mice. Hepatotoxicity was also reported. Benzo(a)pyrene can cross the placenta and was found to cause adverse developmental and reproductive effects in…
For several years Bisphenol A (BPA) has been used in many plastic bottles and metal based food and beverage containers and have thought to be safe. However in 2012, researchers argue that they have some concern about the potential effects of BPA on the brain, behavior, and prostate gland in fetuses, infants, and young children. The FDA is taking steps to reduce the exposure of BPA by supporting actions to stop producing BPA - containing baby bottles and infant feeding cups, developing alternatives to BPA for the linings of infant formula cans and supporting he efforts to replace BPA or minimize BPA levels in other food can linings.…
BPA or Bisphenol A is a hormone mimicking chemical that is linked to potential health risks.…
It is one of the endocrine disrupting chemicals and that has caused some concern regarding exposure to BPA and its effects on the human body. Laboratory studies also indicated gene mutation as a potential effect with exposure. BPA stimulates cell proliferation and induces multiplication of oestrogen like cells that initiate mammary gland and uterine differentiation [8].…
Kittrell above and in many instances in his report many instances loosely describes NCRs knowledge that “PCBs” were “toxic”. Routinely both Dr. Rodricks and Dr. Kittrell lump all Aroclors under the one term, PCBs, when the focus in this matter should be on Aroclor 1242 and its differential toxicity and the evolving scientific information available over time for this product. Although there were well-known hazards associated with some PCBs in occupational settings, NCR’s investigations of possible toxicity of its CCP containing Aroclor 1242 (the Hill Top studies) had shown low to negligible toxicity, especially at lower concentrations. As described in my earlier reports, NCR had no scientifically credible reason to conclude that the potential toxicity of CCP and its components would likely result in risks at environmental levels of exposure.…

Department of Health and Human Services regarding minimizing an infant’s exposure to BPA is that parents should examine discard scratched baby bottles and infant feeding cups, as if these old containers contain BPA it could be released in small quantities into an infant’s system ("Bisphenol A (BPA),"). Another factor that was found while researching is the fact that a high temperature used to heat your infant’s formula can dispense more BPA into the formula than heating with a hot water bath. As a result, the HHS suggests that parents should not ever heat baby formula in a BPA container in the microwave because not only a burn to the infant’s mouth may occur, but there may be a higher dose of BPA being administered to the infant ("Bisphenol A (BPA),"). The last suggestion for minimizing the exposure of BPA to infants, is for parents to read the labels on plastic containers relating to the recycle codes. The recycle codes that are likely to not contain BPA are 1, 2, 3, 4, 5, and 6, while recycle code number 7 is likely to contain…
Åke Bergman of Stockholm University tells me he has received the results of a chemical analysis of my blood, which measured levels of flame-retarding compounds called polybrominated diphenyl ethers. In mice and rats, high doses of PBDEs interfere with thyroid function, cause reproductive and neurological problems, and hamper neurological development. Little is known about their impact on human health.…
Mike Skinner is a researcher from Washington State University. He investigates chemicals, like DDT and mixture of BPA and phthalates, which can cause obesity and reproductive biological problems5. Leonardo Trasande from New York University Medical School studies levels of BPA in urine, the BMI of children and its relation to obesity. University of California, Irvine researcher Bruce Blumberg studies obesogens, endocrine disruptors and TBT effects on hormone receptors3. Endocrine disruptors are chemicals, when absorbed in the body either mimic or block hormones, disrupting the body’s normal functions. It includes DES, dioxin, PCBs, and other pesticides2. Rob Sargis studies effects of endrin, tolylfluanid and BPA on the glucorticoid pathway7. With increasing obesity rates, many scientists believe chemical exposures that mess with hormonal pathways make the human body more susceptible to obesity2.…

Exposure to medications or drugs during pregnancy can result in abnormalities such as withdrawal symptom, respiratory problems, growth retardation, developmental retardation, congenital heart defects, caudal deficiency and CNS defects. Known prenatal birth defects resulting from environmental toxins such as Lead, mercury or PCB's are miscarriage, CNS damage, spasticity, mental retardation, skin discoloration and low birth weight. Only some defects resulting from diseases are listed, these are CNS disease, neonatal death, failure to thrive, infection, miscarriage, abnormal teeth, limb reduction, hearing impairment and mental deficiency. Research provided from the University of Dakota support these results to teratogens. The University of Dakota and The University of Michigan suggest that conditions resulting from exposure to teratogens can vary in severity depending on factors such as age and prolonged…
Public rhetoric is one type of communication theory, of which the narrative paradigm by Walter Fisher is an example. The movie Big Fish will be analyzed in this paper using Fisher's narrative paradigm to show that all types of communication can be regarded as story (Griffin, 2006, p. 340).…
