瓶装矿泉水不一定比自来水健康

Study: Bottled Water No Safer Than Tap Water

根据 Mark Baumgartner 的调查报告：


1。瓶装水不一定比普通自来水安全健康。

2。塑胶瓶(plastic bottles) 会溶滤出有毒性化学物，

    特别是经过回收重用的塑胶瓶。为了健康，用过的塑胶瓶最好不要再用。

Bottled water is the world's fastest growing beverage, but consumers would be better served by simply turning on the tap, asserts environmental groups.

Bottlers of water generally capitalize on consumer concerns about municipal water supplies, creating demand for their product via an association with pristine environs. Some bottled waters, however, differ from tap water merely by being distributed in bottles rather than through pipes, according to a report commissioned by Switzerland-based World Wildlife Fund International.

"Bottled water may be no safer or healthier than tap water, while selling for up to 1,000 times the price," the report said.

The reason, according to the environmental group, is an absence of standards regulating bottled water. "In fact," said the report, "there are more standards regulating tap water in Europe and the United States than those applied to the bottled water industry."

WARNNG; ARE PLASTIC BOTTLES SAFE THAT CARRY OUR BOTTLED WATER? (look for #7 bottom of your plastic bottles)

Most types of plastic bottles are safe to reuse at least a few times if properly washed with hot soapy water. But recent revelations about chemicals in Lexan (plastic #7) bottles are enough to scare even the most committed environmentalists from reusing them (or buying them in the first place).

Chemicals May Contaminate Food and Drinks in Reused Plastic Bottles
Studies have indicated that food and drinks stored in such containers—including those ubiquitous clear Nalgene water bottles hanging from just about every hiker’s backpack—can contain trace amount of Bisphenol A (BPA), a synthetic chemical that interferes with the body’s natural hormonal messaging system.

Reused Plastic Bottles Can Leach Toxic Chemicals
The same studies found that repeated re-use of such bottles—which get dinged up through normal wear and tear and while being washed—increases the chance that chemicals will leak out of the tiny cracks and crevices that develop over time. According to the Environment California Research & Policy Center, which reviewed 130 studies on the topic, BPA has been linked to breast and uterine cancer, an increased risk of miscarriage, and decreased testosterone levels.

BPA can also wreak havoc on children’s developing systems. (Parents beware: Most baby bottles and sippy cups are made with plastics containing BPA.) Most experts agree that the amount of BPA that could leach into food and drinks through normal handling is probably very small, but there are concerns about the cumulative effect of small doses.

Even Plastic Water and Soda Bottles Should Not Be Reused
Health advocates also recommend not reusing bottles made from plastic #1 (polyethylene terephthalate, also known as PET or PETE), including most disposable water, soda and juice bottles. According to The Green Guide, such bottles may be safe for one-time use, but re-use should be avoided because studies indicate they may leach DEHP—another probable human carcinogen—when they are in less-than-perfect condition
