The research by Hunt and others led the U. The Washington Legislature has also limited its use. They said mice exposed to BPS experienced changes in how the germ cells in their testes and ovaries copy and splice DNA while producing sperm and eggs. The researchers also found the issues occurring in the male germline lasted several generations after the initial exposure.
Where can I find more information on plastics? How is plastic made and identified? How many times a day do you use something made from plastic?
Plastic has been a part of our lives for over years, and its use continues to grow. Inabout billion pounds of plastic were produced in North Bpa plastic. Recently, claims have been made about certain types of plastic being unsafe.
Are we getting more than just storage when it comes to using plastic? The process of making plastic is a complicated one. It begins with carbon from petroleum, natural gascoal, or biological sources.
The elements can be combined in various combinations in order to achieve a desired property and characteristic. The final product can be hard like the siding on your house or soft and flexible like shrink wrap. Have you ever noticed the number with the arrows surrounding it on your Bpa plastic bottles?
Many people use these numbers to determine how the product is to be recycled. These numbers are called the plastic packaging resin identification codes. They indicate the type of plastic that the item was made from and are used to help consumers know whether and how the item is to be recycled.
According to the American Chemistry Council, the resin identification numbers are as follows: For example, the plastic that is approved for use in your microwave has been approved for that purpose, while the plastic that carries your water was approved for that use, as well. Food and Drug Administration FDA admits that something will always "leach out of the container and into the food," so they try to determine the amount that someone will ingest over a lifetime versus the levels of a given substance that are known to be toxic.
Their goal is to make sure that during our lifetime the amount that we consume will not pose any risk to our health.
But what if their estimate of how much we consume is incorrect? What if the product containing plastic is not used according to the directions?
These questions could be lifesaving ones. The first step is to know what kind of plastic is in your cabinets. Read what the government and industry say. Bisphenol A is a chemical found in polycarbonate plasticand epoxy resins.
Polycarbonate plastics are used in certain food and drink packaging and also in compact discs, computers, impact-resistant safety equipment such as helmets and gogglesand medical devices.
Polyethylene terephthalate PET is clear, tough, and shatterproof. It provides a barrier to oxygen, water, and carbon dioxide and is identified with the number 1. Take a look at the bottom of your soft drink bottle and you will most likely find a number 1 there.
PET is also used to make bottles for water, juice, sports drinksbeer, mouthwash, catsup, and salad dressing. You can also find it on your food jars for peanut butter, jam, jelly, and pickles as well as in microwavable food trays. InILSI stated that "PET polymer has a long history of safe consumer use, which is supported by human experience and numerous toxicity studies.
For example, the microwavable trays are only to be used one time and not to store or prepare foods other than those for which they are intended. Recent studies have shown that reusing bottles made of PET can in fact be dangerous.Scientific American is the essential guide to the most awe-inspiring advances in science and technology, explaining how they change our .
For many years, plastic has been the top choice for manufacturers looking to produce water bottles.
The lightweight and durable nature of plastic can make it a great asset, but there are also a number of problems that come with using this material. Many plastic products are said to contain BPA, or.
Bisphenol a (BPA) is the widely used chemical found in many plastics, food can linings, and even on US dollars and receipts. Known as an endocrine-disrupting chemical that mimics the hormone estrogen, BPA has been linked to numerous negative health effects in countless studies.

Metal Cans Also Contain BPA Polycarbonate plastic bottles and food containers are just one potential source of the BPA in our bodies.
BPA is also used in the epoxy resin that. BPA is an industrial chemical added to many products, including plastic food containers. This is a detailed review of BPA and its effects on your health.
