Plastic and Water

Plastic bottles are made of oil and other substances such as polyethylene terephthalate (PET), and polycarbonate. In overtime period of time if water remains in those plastic bottles won’t that effect the water inside? Believe it or not it does affect the water! Harmful toxins eventually go on the loose by all the chemicals provided to manufacture the plastic bottle. Polyethylene terephthalate (PET) releases chemical called antimony, as it is claimed by geochemists in Germany. (1) I went further, looking for what antimony embodies and this is my encounter: (2) "Uses of Antimony: Used to harden lead alloys. Also used in solder, bearings, lead batteries, mascara, infrared detectors, plastics and chemicals. " "Additional Notes: Antimony used to be used to provoke vomiting, but the medical dose was too close to the fatal dose. Small does stimulate metabolism, but large doses cause liver damage and can kill. " Scary, I would say! Just take a look at the resourceful website. The polycarbonate plastic bottle also releases a damaging toxin which is the chemical bisphenol A (BPA). A study made by senior investigator Karin B Michels, associate professor of epidemiology at Harvard School of Public Health (HSPH) and colleagues, discovered that people who drank from polycarbonate plastic bottles in a week of investigation, had two-thirds of BPA in their urine. Other concerns are that BPA has been linked to cardiovascular disease and diabetes in humans, among other things. (3) Right now you must be in a great deal of astonishment as probably some of this information was new to you. Additionally, most of these plastic bottles are not recyclable making mountains of garbage because it is indestructible material. Somehow, all of this doesn’t make any sense. Why are we humans inventing things that are destroying us? Are there any other alternatives to hold our water safely? Of course there is.

The Dangerous of Bottled Water

　 Do you usually buy bottled water to drink from instead of drinking the tap water from your faucet? I’m sure the reason for buying bottled water is that you think bottled water is extra clean and purify which comes straight from a spring. So many times, we hear that water faucet it’s not drinkable. The reasons are countless from broken water pipes to some bacteria that got into the water. This kind of alerts makes us buy bottled water thinking that we will be all right by doing so. Surprise of all the surprises many of these bottles of water come straight from tap water. According to David Zinczenko, with Matt Goulding, an editor-in-chief of Men’s Health, usually tap water is subject to take products to purify it so it can be drinkable besides it has to pass strict state, federal and local guidelines; on the other hand, bottled water is not subjected to the same strict national and local standards. (1) A 4-year study on bottled water has been made by a marketing class from Cornell University. What they found is something to be alarmed of. About 22% of bottled water brands were having more then water inside. Chemical contaminants above the normal were inside the water. (1) Now a question is raise where do these chemical contaminants come from. Is it already in the water while is bottled or is it from the plastic container that holds the water? 　 For more information check here: (1) http://health.yahoo.com/experts/eatthis/34361/the-truth-about-bottled-water/
