Perfluorooctanoic acid

River. Teflon is a non-stick coating commonly found on water-resistant clothing, cookware, among other things. One of the main byproducts of Teflon is perfluorooctanoic acid (PFOA), more commonly known as C8. DuPont 's Washington Works plant released C8 into the air as well as the Ohio River until 2001, at which point abnormally high levels of the acid were detected in drinking water supplies throughout the river in Little Hocking, Ohio. The Little Hocking water system consists of five groundwater

For some years now there has been quite a bit of controversy as to whether the non-stick Teflon coating on pots and pans is actually harmful to humans. However, more recent there has even been rumor that this marvelous invention that every kitchen maid loves, may actually cause cancer. So how much of this is fact, and how much is just myth? First of all, it may be prudent to explain exactly what Teflon is. Teflon, is the registered trademark of a man-made chemical known as polytetrafluorothylene

The article, "PFOS found almost 31 times EPA's advisory level at Issaquah well", is about an incident that happened in Issaquah, WA where the wells in the city displayed a level high of perfluorooctane sulfonate. The displayed level of PFOS was extremely higher than the advisory level provided by the Enviornmental Protection Agency. The Monitoring Wells No. 6, 5 and 3 were all tested for PFOS, and the results for all three wells were higher than EPA's standards. The Eastside Fire and Rescue headquarters

Research Strategy A. Significance and Background Obesity is a major public health concern in the United States and worldwide. Recent data suggest that more than 70% of the U.S. adults 20 years or older are overweight or obese (CDC 2016, CDC 2015). Obesity is associated with numerous serious health sequelae, including cardio- and neuro- vascular diseases, diabetes, and several types of cancer and incurs substantial medical costs (CDC 2015). Given the seriousness of the public health concern, there

organfluorine chemicals, containing a chain of carbon atoms surrounded by C-F bonds often with a charged functional group in the end. The fluoroalkyl chain normally exhibit hydrophilic property, while the typical functional group such as sulfonate salt or acid tends to be hydrophobic. These unique characteristics make the compound oil and water repellent at the same time, which contributes to the widely application in the industrial and domestic products: upholstery, textiles, carpet, lubricants, foam in

Module 01 Homework Assignment Use the information presented in this module along with additional outside research to answer the questions: 1. Describe how applied microbiology is used to improve aspects of life and the environment. Microbiology is the study of microorganisms (VanMeter, VanMeter, & Hubert, n.d., p.3). These are all of the things not visible to the human eye. With the study of microbiology, it enables us to find things such as viruses and bacteria. This is helpful because

1. Soccer is one of the most demanding of all sports. The game is played on one of the largest fields of any sport, for the longest sustained time and with the least amount of breaks. Players in a soccer team are in continuous activity as they compete for loose balls, move to encourage teammates, rotate positions and run to make a space or test opponents. Running, jumping, sprinting movements in relation with sudden changes of acceleration and route outweigh the play. The power of the game ranges

group of protein and protein can break easily by acid, base, and hot temperature. To experiment our question, we used catalase solution, 3% H2O2 solution, 0.1 M HCl solution, 0.1 M NaOH solution, a beaker, an O2 gas sensor, sensor interface on a Chromebook, pH paper, and safety gloves. Therefore, we conducted experiments to test how enzyme activity in different conditions. Plus, we predicted that if temperature increases or enzyme have contacts with acid or base, enzyme activity will decrease. We

Meat Tenderness, and Consumer Perceptions Introduction The current climate of the relationship between the food-producing industry and consumers is volatile. Current self-appointed consumer leaders such as Vani Hari, known as the “Food Babe” (foodbabe.com) pressure food industry sectors for changes in products. Reasoning for these changes largely reside in the practices of fear-mongering, using terminology outside the knowledge of the readers these leaders attract, exacerbating worst-case scenarios

Determining the pH of Household Items March 22, 2016: Sara, Sam Introduction: Everyday household items can be seen as just “household items”. However, it is often not realized that we could actually determine the pH very easily. It could also be important to know the pH in everyday life. For example, it is important to keep track of human pH levels. Some people are curious to see the pH of their own body, which is a great use to keep acidic levels leveled. Another use in real life is determining
