It regularly asks us the best material for storing water. Here first of a newspaper article and a few tips:
Glass or plastic for our mineral waters.
It is a controversy that has spilled much ink! What should we think? Is the danger of plastic really so important? Recognize that the basic material used for making plastic bottles, PVC (Poly Vinyl Chloride) is not safe.
Experiments showed carcinogenic potential in animals. Workers involved in the PVC manufacturing plants also seem to more easily develop cancerous manifestations that workers in other branches of industry in general. For a consumer who is in contact with the finished product and stable, this is another situation that we will qualify. An interesting experiment was conducted by the Laboratory of Toxicology of the Faculty of Sciences of Toulouse. Here are the results.
Plastic is dangerous, but yes!
The experiment involved measuring the level expressed in ppm (parts per million), ie the finest research at the limits of homeopathy, PVC contained in a 1.5 liter bottle of Mount Roucous water.
Two measurements were taken:
- A dosage corresponding to a few weeks the water stay in the plastic bottle
- A dosage after a stay of water a year in the plastic container.
It’s extensive experience as a bottle of water is generally not stored too long before consumption.
- Premier dosage: 0 ppm,
- Second dosage: 2 ppm of PVC.
It must be recognized that we are here in a homeopathic sub-scale and at this dose no danger exists. But then where is the problem? It does not come directly from PVC, but the liquid that is in contact with him …
When the test is done with highly mineralized waters like Evian, Contrexeville, Vittel, Vichy, the last containing up more than 4 grams of bicarbonates, sodium salts, we find very large quantities of PVC in the salts of these waters.
When water contains traces of minerals, there is no hydrolysis and PVC remains stable. Remember that water Mount Roucous has an electrical resistivity of 40000 ohms (almost pure rain water) and water Contrexe city only 300 ohms.
Take the test yourself!
Another interesting test that every consumer can make itself is to compare the strength of an empty bottle plastic that contained a highly mineralized water with an empty bottle that had contained a water-Volvic, Mont Roc Roucous or Katel … the first bottle is very brittle, the second retains its elasticity.
The physical qualities are, also, highly modified and altered. Many consumers remember the problems encountered there a few years at the instability of PVC when it is in contact with highly mineralized water.
We recently just had confidential information provided by fasteners biologists controls the stability of PVC packaging of these great sources. These experts did not hide their concern us. The problem remains … Not only the Ministry of Health should ban mineralized waters below 5000 ohms, but ban plastic bottles for these waters, which further aggravate the poisoning of consumers. We will never remember it enough, it should be bottled in PVC as light water, others are consumed directly griffin.
For highly mineralized water, packaged in glass or plastic bottles, they should be banned, so the choice remains, glass or plastic, for mild waters. Glass is more unstable than we think.
The Toulouse Toxicology Laboratory conducted other very interesting experiments. These specialists have left the water Mount Roucous for a year in a glass bottle.
Result: they did not have to dose PVC but dissolves lead salts! Why this lead? Simply because it is one of the glass components associated with silica, often in small quantities but still combined. It was to be expected, the glass is not resistant to water and a mild acid (pHmoins 6.5) … Certainly, the amount of lead is still within acceptable standards, more rarely to store water also long time. It should however mention this experience to open the eyes of some fans of the drink.
The real dangers of PVC. Once again, trenches and Manichean positions do not correspond to reality. The truth is more elusive. The low mineral pure water presents no danger to the consumer when it is in plastic.
The latest water bottles are made of PET. This material does not contain bisphenol A, unlike reusable flasks or bottles, made of polycarbonate. BPA is also found in the linings of cans and cans as well as in drinking water systems (coatings of pipelines).
Identify types of plastic water bottles:
3 PVC or V: Polyvinyl chloride
Common uses: food boxes, mineral water bottles like WaterBottlesShop, food films, bottles, toys. PVC is considered a material that is both dangerous to the environment and health. It contains DEHA. Cadmium or organotin compounds are toxic substances commonly used as stabilizers in PVC.
7 Other or Other: Usually polycarbonate
Common uses: food containers (bottles of ketchup …), bottles, 20 liter plastic bottles, water bottles, rigid plastic cups (usually rigid, translucent and colored). Contains bisphenol A.
Food Plastic Usage Tips
- Avoid running plastic containers in the microwave: do not trust the words “microwave” often baseless.
- Avoid using plastic film, and if you use them, they avoid contact with food.
- Water bottles plastic, PET (category 1) are not affected by BPA, and are considered non-hazardous.
- Warm preferably food or liquids in glass containers.
- Avoid getting fatty foods in plastic containers or UPTIME strong detergents for washing: they increase the release of bisphenol A.
There is probably no perfect solution. For example, we do not know all the components or decorative surface treatment of containers of sandstone … However, one thing is certain: over the container is big plus the volume / surface decreases; in other words it is advantageous to favor containers of larger volume (regardless of the material chosen) and avoid small.
