As we know, we are not encouraged to keep using the same plastic bottle for a long time as a chemical substance which may be harmful to us might leach out. According to Yahoo!Green website, that substance is actually called BPA. It is used in the production of polycarbonate plastics (reusable drinking bottles and baby bottles), epoxy resins (canned food linings), and white dental sealants. It is also added to certain types of children's toys to make them more flexible. According to the researchers, a low-level exposure to BPA is not a problem, but constant low-level exposure may be harmful, especially for children whose bodies are still developing.
The Centers for Disease Control and Prevention had recently conducted a study and found BPA in the urine of 93% of the 2,517 participants analyzed. Those researchers also believe that BPA may have hormone-like effects on reproductive system and neuro-behavioral changes in the offspring. Now, the consumer demand is forcing the manufactures to stop its distribution. We are urged to look for plastics that are marked BPA-free. I enjoyed reading this article because it is related to our daily lives. Source: http://green.yahoo.com/blog/forecastearth/90/what-s-the-big-deal-about-bpa.html
