Today it is more from habit than necessity, since the water from most water is still drinkable, but if for some reason not to drink tap water rather than buy one or the dispensed from plastic containers, check out what these bottles work. Wondering why? For the chemical composition of plastic. Plastic is the name for a variety of artificial or poluumjetne polymer materials, but not all plastic bottles are equally dangerous. At the bottom of each package, see the triangle with the number in the middle. He tells how dangerous your plastic.
1 - PET - often TOE - These bottles are in most cases intended for single use. There is a possibility that emit heavy metals antimony and EPA chemical substance, which interferes with the action of hormones. These bottles can be discharged and the cancer compounds.
2 - CWS - formerly and HDPE - This is a good plastic, for which there is least likelihood of releases of chemicals into the water.
3 - PVC - sometimes 3V - This two plastic releases toxic chemicals , and both interfere with hormone action in the human body. Nevertheless, it is still commonly used for plastic bottles.
4 - LDPE - Plastic, which does not release chemicals into the water. Nevertheless it is not used for making plastic bottles, but mainly to produce plastic bags for groceries.
5 - PP - Another of the good plastic, usually white or translucent color. used for bottles that are packed in syrup, or a cup of yogurt.
6 - PS - Plastic water that is released to the carcinogenic substance Styrene. most commonly used in coffee cups for single use, or in fast food packaging.
7 - PC - or no label - This is the worst plastic for food products, because it secretes a chemical BPA. Unfortunately, it is used in baby bottles, sports bottles and containers for food storage.
plastics, which do not release chemicals into the water are, therefore, 2, 4 and 5, and labeled HDP, HDPE, LDPE, PP. For all others prefer to consider their use. It is still best to keep water in glass bottles.
not devote enough attention to only part of the water, we should not ignore the composition of the packaging in which it is located. near future we indicates that the drinking water in the world less and less and is only a matter of time when we, unfortunately, more and more water to drink water from plastic bottles. most dangerous plastic containers are the ones with labels 1,3,6 or 7 water in these bottles is susceptible to chemical or temperature effects, and the subsequent filling and bacteriological. preferably jars were, but they are impractical, therefore we recommend aluminum bottles - not plastic, because the prices are usually the worst plastic - with a protective sleeve that separates the content of aluminum.
