Bisphenol A (BPA) is a plastic additive known to cause health problems in infants. According to a new study from researchers at the Harvard School of Public Health and associates, BPA may also be responsible for emotional and behavioral problems when the fetus is exposed in-utero.

BPA hit the media several years ago. Commonly used items like children's toys, pacifiers, baby bottles, canned foods and dental sealants contain BPA. Research studies on the effect of BPA on humans found exposure to BPA increased the risk of diabetes and cardiovascular disease. One study noted a significant increased in urine BPA from drinking bottled water. The results of these studies changed how BPA was used in consumer products, but the chemical is legal.

Most of the studies investigated the effect of BPA from direct exposure. This study, however, shows that BPA starts affecting infants well before they come in direct contact with BPA-containing plastics. Jow Braun, the lead author of the study, found that maternal exposure to BPA has a marked impact on the emotional and behavioral health of children born to the mother. This means BPA exposure starts in-utero.

The study included nearly 250 women and their children. The children in the study were 3 years old, at the time information was collected. During pregnancy, urine samples were collected from the mothers. At the time of birth, additional urine samples were also collected. Urine samples were also collected from the children in the study. All urine samples were tested for BPA. About 85% of the maternal urine samples tested positive for BPA. About 96% of the urine samples provided by children tested positive for BPA.
When mothers were asked to answer questions about behavior, researchers found a clear connection between BPA and behavioral problems. None of the problems were clinical in nature, but there were clear changes in behavior, including hyperactivity and aggression. Furthermore, when all outside factors were taken into consideration, higher concentrations of BPA lead to greater behavioral side effects.

It is important to note that maternal urine samples showed a steady BPA level during and after pregnancy. The samples provided by the children in the study showed a marked increase in BPA from age one to age three. More BPA may lead to greater negative side effects.

The best means of reducing the risk of BPA-related behavioral problems is to reduce exposure to BPA. Canned foods, prepackaged foods and water bottles tend to contain BPA. Look for the number 7 on the bottom of water bottles.

1. Ingeo is made from dextrose (sugar) that is derived from field corn already grown for many industrial & functional end-uses. It is a bi polymer

2. It is a thermoplastic because it becomes plastic on heating and harden on cooling and are able to repeat these processes.

3. This plastic can be used in packaging manufacturing.

4. Ingeo is recyclable. It can be remade into a bottle or other types of plastic.

It is not harmful, it is in fact good for our environment.

Poly Vinyl Chloride is made by the electrolysis of salt water that produce chlorine which then is combined with ethylene that has been obtained from oil. A poly Vinyl is Thermoplastic. It is used to make pipes, pipe fittings, pipe conduits, vinyl flooring, and vinyl siding. PVC is recyclable. If it is not used anymore, we won't have mixed plastic materials anymore. PVC is harmful to the planet.

Polyvinyl Chloride- (Vinyl)

1. The basic materials for PVC come from salt and oil. Chlorine is made by the electrolysis of sodium chloride, salt. The electrolysis of salt water produces chlorine. The chlorine is then combined with ethylene that has been obtained from oil. The resulting element is ethylene dichloride, which is changed at very high temperatures to vinyl chloride monomer. These monomer molecules are polymerized forming polyvinyl chloride resin.

2. It is a thermoplastic because it is reversible, and can be reheated and formed again.

3. PVC, commonly known as vinyl, is one of the most widely and commonly used plastics which is a part of our everyday lives.  The most common use is to make PVC pipes which  bring water into our homes and its also used for vinyl windows, electrical conduit, insulation for records, electrical wiring, flooring, vinyl fences, etc. PVC pipe accounts for more than 70% of new buried water pipes being installed in the United States and Canada.

4. PVC is recyclable, and the most common method for this today is mechanical recycling a process that grinds the material into a powder base for new plastic products. The benefit of recycling PVC is that new products can achieve equal quality to originals, while many other types of plastics may only be downcycled into lower-quality products.  The majority of PVC is thrown away after the consumer is done as opposed to recycling it and it is the least recycled plastic .

5. Chemical additives and heavy metal content have made PVC to be a very polluting form of plastic, both when burned and when buried in landfills. The material has been found to leak chlorine, carcinogens and other toxic chemicals into the soil and air over time within landfill or incineration disposals.

1)Was invented and produced in 1933, by Imperial Chemical Industries using a process called free radical polymerization. This is produced by applying great heat to petroleum causing monomers to link and create a polymer.

2) Low-density Polyethylene is a thermoplastic made from ethylene. A thermoplastic is typically a polymer that is pliable or moldable  above a certain temperature, and solidifies upon cooling.

3) It is used in lining of trash bags, plastic bags, food containers and water bottles.

4) Less than 6% of this type of polymer can be recycled. It is typically sent to a dump, or it resonates in the ocean with other plastics.

5) Isn't completely toxic to the environment however it is hard to degrade allowing it to collect in the ocean.

Polyethylene terephthalate or PET is a modified ethylene glycol and purified terephthalic combined to form the polymer called polyethylene terephthalate.

Its used for many beverages like food items and other consumer products are delivered in bottles or packages made from PET.

Manufacturers like it because it’s safe , strong, transparent. It is also recyclable.

When it’s no longer in use we recycle it to make new bottles, fiber for carpets; fabric for shirt, winter coats also use it for automotive parts such as headliners, bumpers and door panels.

Fragments in the waterways absorb toxins and pollute our waterways, contaminate our soil and sickens animals.

It also may take centuries to decompose while sitting in landfills.
